I have a 2006 Dodge Ram 1500 2wd 6 speed. Bought it in 2016 with 87,000 miles. It now has 218,000+ miles. Oil changes every 3000 miles. Five quarts go in, five quarts come out. Best used vehicle I have ever bought.
I just bought a 3.7 engine from you guys this evening .and new Mopar brand oil pan and intake manifold from mopar parts store. I have heard nothing but great things about and from you guys. My jeep has 265,000 miles on it , and still runs like a top with no check engine lights , on a jeep imagine that😂 , but with all them miles on it and i do alot of overlanding fishing trips in the middle of no where it is time to retire her old engine. So cant wait for the new one i live in PA , and thanks for making a great product at a fair price , from a retired vet i thank you.
I have a 2008 jeep commander with 231,237 miles and when I first got it, it was using some oil and a few odds and ends, did some engine cleaning and other stuff, now it uses nothing. There’s a little lower end noise but it’s Been looked at many times and I’ve been reassured it’s alright. Over all what I’m saying is you take care of your engine and the 4.7l and it will last you, my jeep is running very strong still.
I had purchased a 2002 Jeep Liberty Renegade just last Thursday for $1000.00 cash. The body was nearly flawless, and the interior had only shown normal signs of wear. I was told that the engine was seized. I made the deal, I towed it home and set the charger on the battery for a day. The next day after work I went out to turn the key just to hear what the starter would do, whether it would click, buzz or nothing. To my surprise the engine had turned over! It didn't start though at first, but once I gave it a little gas it started right up! It wouldn't idle, but the engine did run. This Jeep has 199,000 on the clock. I have the perfect platform for a project. Yes, those little 3.7L V6 engines are built well.
@@shanejones578 maybe intake manifold leaking and sucking air? I had a 5.3L gm that ran like poo cold in the winter and I put some of the expensive felpro intake gaskets in it and it fixed it.
These are solid engines indeed. I bought a 2001 Dakota SLT 2WD w/ the 4.7L and 195,000 original miles from an impound lot. I was hesitant to buy it, but I talked the salesman down to under a grand. It seemed to run well, just had a power steering leak, needed some minor suspension work, and a couple window motors. I've owned it for 14 months now and its just about to hit 200,000. I've updated all the maintenance and done some preventative maintenance as well. It runs strong and is a fun truck to tinker around with. I smile every day as I drive it because I have no car payment and only about 2,500 into it at this point (including the purchase price). I'll seriously consider one of these engines if anything happens to it in the future. I know I couldn't replace it for less than 5 to 7 grand with the condition it's in.
2006 Dakota with 3.7L v6 Quad Cab RWD and 266,000 miles. Adequate power. Have only changed the water pump and spark plugs. Used full synthetic since 20k miles. Gets 22 mph on the highway. Very easy to work on.
Bought a 2004 Ram 1500 with 3.7 and broken timing guides. Took a chance with same engine putting new timing kit + oil pump, and success! The plastic guides are pretty dumb for longevity (like ford tritons) but solid engines when kept up
I purchased my 2000 WJ 4.7L JGC in 2015, got it at a throw away price because of the engine ticking noise (at it was advertised). The engine KNOCK was due to a spun big end so I purchased a full reco engine from HM engines is AU. The engine was actually a HO version so when installing it I also upgraded the throttle body and ECU to match. I love the off the line power and its such a great car for cruising at 110Km/hr
Am interested to know the background of the PowerTech engines when they were first developed by American Motors before the Chrysler takeover. Was the AMC V8 used as a starting point or given the role Renault played at the time, did AMC rather utilize the PRV V6 instead as a starting point an enlarged V6/V8 (via a longer stroke) on the basis the PRV shares the same 93mm bore as the PowerTech engines (along with the fact the PRV V6 itself was originally conceived as a V8 during development)?
Because of the value train design a full synthetic motor oil is a must 5W30! As I said because the valve train design valve stem cooling has to be via the motor oil to help cool the valve stem transferred into the valve seats intake if not? The seats will over heat break crack then fall apart sucked down into the cylinder destroying the engine. Over the years I've worked on these two engines this is always what I've seen as the main problem...
Just rolled over 200k on my 2008 Ram 1500 lifted 4WD with the FFV 4.7! I have 3.92s front and rear with LSDs, so that definitely gave some pep in it’s step as far as extra torque is concerned! I’m planning to replace my engine because my truck is still too damn nice!! Re-engineered flaws is music to my ears honestly! I love my black on black Dodge!
Nice. Same here. Changed to detroit rear and other small various things. At 270,000 and no smoking..never left me stuck or dead in winter and pulled everything iv thrown at it., will def be maintaing the midsize dakota..
I've had over 20 vehicles in my life, and my 2000 Grand Cherokee is the one I've had the longest for the most miles. 249k and still running strong, never an issue. And yes, It IS better then a Jeep 4.0 which I had before. The only issue is if you over heat them. Iron block + alum heads. Not really the engines fault. Owners not doing proper maintenance or pulling over if a problem comes up. Easy to work on, plenty of power, silk smooth.
I have a 2011 Ram 1500 since new and just hit 217,000km (135k miles) and just developed a wicked ticking in the top end, which is really loud at cold start but quiets right down after it heats up (about 15 mins). Could be failed lash adjusters or valve seats, both known issues with this motor. Will be looking into your motors and shipping to Canada.
I have a 2008 3.7 L V6 Dodge dakota RWD Quad Cab with 67000 miles. Change oil every 3K miles with on sale Syn blend (phillips 66) or Conv oil (shell or penzoil or Quaker). Set the cruise at 70 MPH get 20 MPG. All around driving 17 MPG. 15 city. Wished gas mileage was a little better but it has been a good running engine. Keep the oil clean. But I live in Kansas so it is dusty.
i bought a 2008 dodge ram 1500 with a 4.7 in it. I see on the engine that its a 2010 4.7 and its almost at 200k on the odometer. Im not sure when the engine was replaced but it has no engine lights and runs great.
Have a 2003 Durango SXT that I bought with 140,000 miles and I love it. Put new spark plugs, need to buy a new throttle body and wanting to buy a better cam cause the stock one isn't very good
I have a 2008 dodge ram with a 4.7 v8 in it but after some research it has a either a newer 2010 4.7 or a rebuilt engine with 2010 parts. not sure as I have not dug into internals. but it runs great with 187k miles on it.
The updated version came out in 2008, before the next generation of RAM trucks came out. So you most likely have the original 310hp engine that came in the 2008 model, unlike the 2007 and earlier which had the older 4.7 generation.
I have a 2008 1500 with the 3.7l she’s got 226000 on her and just started burning oil. The only thing I’ve changed so far is the water pump. This engine is a work horse. Would love to put a 4.7 for more power but don’t know how to go about it
Shitty lash adjusters, and the seats if they are overheated. I bought my 04 4.7 HO Grand Cherokee cheap ($500) because of a popped rocker due to a lash adjuster. Put rebuilt heads on it with solid lash adjusters, almost 200,000 miles and runs excellent.
I agree it is nowhere near as bad as the 5.4. I am a Mopar guy. But the valve seat issue was there from 99 to 07. Only the dual plug heads are immune to valve seats dropping. And the rocker arm usually comes out when the seat drops. So IDK what we are arguing about...hahaha Have a good one
I'm thinking Powertrain for my WJ 01 4.7-4.7HO update. My current engine #2 is still running clean, clean only 118,000 on it. But I've got the money and more horsepower reliably is ideal. Would I blow it? I wouldn't go that far. But the 4.7-4.7HO is sounding like the route.
So ill say this. I Drive ALOT. My commuter car is a vw tdi with 405k. Many years ago. I made my first big boy purchase, a low mileage 2008 ram with a 3.7. All it needed to do was haul a fourwheeler and go out on dates ( it was just clean and pretty all its life) and then i grew older and the toys and work life got bigger. That 3.7 lived off the rev limiter. Just of 2 years ago, i sold the truck in beautiful shape. An original 3.7 that was worked its a$$ off, purred like a kitten, didnt burn a drop of oil, didnt drip any fluids, with 380thousand relentless teenager style driven miles. The old man still drives that truck with a smile. And i oughtta kiss that truck because ive assumed all these years that the 3.7 was actually a bad engine and i was just blessed. Maybe still the case now. I have a jeep liberty with a 3.7 with only 180k. Does have its obvious leaks i gotta fix. But it sounds and runs solid. I think the 3.7 and 4.7 are just those motors they really performed and lasted pretty well and got a bad rep from the small select numbers of bad individuals, all whole 300+ thousand mile vehicles wjth these engines... well people arent praising and yelling about the fact. Theyre just living life.
Bought a RAM 1500 truck with the 3.7 in it at 53K. it now has 80K on it, so I don't consider mileage like that to be any kind of test. When it hits 150K with just maintenance issues, I'll say something sweet. Til then, it's doing what I expected - runs like a sewing machine.
My 05 GC WK has 200k on the clock, on all original equipment. Change your oil every 3-5k miles, use synthetic or blends for the oil, not the old dino only stuff. Don't baby the engine, the engine needs to be put through its rpm band every now and then. And if you are 120k+ on your miles and still rocking the factory Rad, replace it. They are time bomb and if it fails in a bad way, your engine is toast. They do not like to be over heated. Overheating this engine is pretty much death for it. The Waterpumps need to be replaced as well, they do fail. on my 3rd water pump, replaced waterpump and rad @ 170k miles. Now pushing 200k miles and thing runs like a champ. We put around 2-4k miles on it every month. It has never left us stranded. Like all Powertech Engines at this age, my Valve Covers leak. That and the Exhaust Manifold bolts breaking are two nearly guaranteed problems you will face at some point owning these things. The 545RFE is bulletproof. My GM car's never had as easy as life as my jeep. My old Jimmy went through two transmission rebuilds and a ton of engine components(damn spider injector), as well as a rear diff. Not to mention the crap suspension. She still lasted to 250k before getting rid of her, but still the cost of doing 250k was not cheap. The person who bought if from me had gotten a truck that was nearly half new.
Original owner of 04 ram 1500 with 3.7 with 190k construction sight truck. Batteries,tires,oil(not as much as i should),air filter,pcv,2 pilot bearings and just put in 3rd set of plugs but they still looked like new.Replacing valve cover seals this weekend(starting to weep).That's it! I have been getting nervous because this truck has never stopped.I somehow feel better knowing I am on borrowed time with the water pump.How long will the "lifetime" timing chain last?
@@gueto70 The timing chain will technically last the life of the engine. There's no recommend change interval and very few cases of failure. The key to it's longevity is lubrication. Dirty oil and long change intervals may cause accelerated wear of the chains and tensioners.
@@xc8487 thanks for reply.My truck is having a pessimistic mid life crisis. Truck has worked hard its hole life with no complaints.finishing the last of the suspension,bearing hubs and drive shaft replacements this weekend.planned on replacing lifters next.All the factory parts were good just preventative.never herd of the water pump problem.on my list.
so I got a 2000 Jeep Grand Cherokee with a 4.7 and I love the motor I was wondering if anybody has the 3.6 and if it's as durable because I was looking to buy a newer one and the 3.6 seems to be more, nowadays anybody got comments or suggestions
Lol, I have a 2010 Dodge Nitro with 285,000 on it. Yeah it burns a little oil, but I have a saying when it comes to this car, and that is “there’s 3 things in life you can rest assured on; death, taxes, and the nitro is gonna start in the morning.” The 3.7 and 4.7 are my favorite for the reliability hands down.
Not that he needs any help selling engines ( He's a very good salesman ) But I have about 205,000 on mine and the only issue I have is bad exhaust manifolds. And its actually not all that bad of a job, on the 05 Dakota's anyway. Plenty of room through the wheel wells. The reason the engines drop seats is because people don't realize there is a bleeder screw up top for the cooling system and it 100% must be done every time the coolant is drained for any reason; it must be blead! And for a good period of time, up to 40 minutes in some cases with the heater blowing. Or else bubbles in the system lead to un-even cooling and hot spots in the heads and POP goes the valve seats. The other problem is the rockers(can)fall out due to bad lifer/ "lash adjuster-springs" basically you only need the valve covers off, and from that point on its a matter of just poping the rocker arms off (a plastic clip remover, for autobody will do) Anywho, if you take care of that before there is a problem.. There WONT be a problem. They're good little engines, I'm even considering getting a second one for my 80's dodge that has a manual transmission.. (: (edit: I'm talking about the 4.7 Magnum specifically)
I have an 07 Liberty with 3.7 it has over 315,000 on-the-clock it's an amazing little tank of a vehicle but now I also have a 03 4.7 L in a Ram 1500 and the motor has been ripped out and rebuilt twice and it keeps blowing head gasket I honestly I'm just disgusted with this 4.7 L and I don't know if there's any help for it I'm considering ripping it out and putting a 5.7 in it
I got 140,000 miles out of my 3.7 without any issues before I sold it. My only complaint is the oil filter location. Pain to do oil changes. The 3.7 also has pretty loud valve-train clacking. My biggest issue with Chrysler is their transmissions. The 42RLE was a piece of garbage.
@@chrisohlandt4275 No I didn’t, do your regular maintenance and drive it right and it should last a while it’s basically a Jeep Lol I sold it to my niece 6 months ago I really liked it in the 5 years I owned it. and no warning ⚠️ lights
I'm almost 200k miles and for maintenance reasons I'm replacing the lash adjusters and timing chains along with a few other parts. Maintenance is key, I really love my SW 4x4 02 Ram truck and the rowdy little 4.7 in it and when I die, bury me in it!
my friend has a 2004 Dodge1500 with a 4.7 pickup with 130k miles and used royal purple oil since new and serviced cooling system alot and it still blew the head gasket and is blowing plenty white smoke and can't afford to go buy a new truck. another friend had a 99 intrepid and that motor died at 73k and he changed oil. same thing with my daughters 2001 intrepid 2.7 motor died at 101k miles. then she got a 2011 durango (I told her not to) and had to change the cam and lifters at 153k and the transmission at 157k then dumped it.
The seats never get loose 😂 the valves bend. And hammer the seat till it falls out. Check the run out on the exhaust valves, also look at the exhaust valve springs on the 3.7l with the external shroud
I have one of the 4.7s in my 2013 ram, I got the truck for a STEAL! It’s been a good engine I had an issue with the electronic throttle body but other than that it’s been pretty good, this engine does seem to have serious power loss at high altitudes though, anything over 5k feet it sounds like it’s gasping for air and has no power.
That's what I've read. Another issue is they used single row radiators, so they didn't have as much cooling capacity as they really should have had, they bare minimum'd it. I'm pre-emptively doing a motor refresh on my 4.7, got the heads rebuilt, replacing all the seals, oil pump, water pump, etc. and will also be putting in an upgraded all aluminum (no plastic caps) 4 row radiator. Also swapping out that goofy hydraulic cooling fan for an electric setup.
If only you guys replaced those seats with actual hardened iron ones instead of powered.. and if only you put cast or forged rods in them instead of those ticking time bombs called powdered metal connecting rods.. Why anyone thinks those things are a good idea is beyond me, old school cast iron rods are stronger.
Have a 03 ram 1500 4.7 L 2wd 180,000 miles motor and transmission are perfect hoses water pump and plugs and coils. Oh and a fuel pump is all that was done nothing major @ all
A 454 will fit in a chevette so,,,, sure! The closer the too vehicles are the easier the swap.If the only difference is the name stamped on top not bad.pulling a transverse mounted automatic to bolt up to a in line manual,from a different gen that's more work.
I was a salvage dealer and buyer and by far these trucks with this 4.7 are # 1 in salvage sales and facebook with bad engines. to say these are ok is like saying the F-150 5.4 3 valve is a great engine. not until 2009 is when they corrected some of these issues. but this dude is a salesman.
My 02 ram 4.7 has 180,000 miles have had no problems except for it consumes about 1 quart of oil every 1,000 miles. Smokes on start and very little when driving. Thinking piston rings are worn out. What do y’all think
just looked at buying an '05 Ram with the 4.7 earlier today, took it on a test drive and it ran and sounded good but man was it a dog when i went to accelerate. which is unfortunate because i really did like the truck, but if it seems sluggish on its own then i cant imagine how it would be towing something.
@Rusty Highlander NO! any boost on a stock 3.7 or 4.7 could destroy the pistons because the top compression ring is very close to the top of the piston and can get very hot and expand too much under boost. You can buy forged low compression pistons tho, then i bet it would be a pretty solid boosted v8.
does the 3.7 have the EXTREMELY bad head design like the 4.7..... before anyone argues look in the used market and see how many very very nice rams and jeeps that are dirt cheap with dead 4.7.... ive owned 3. they are now the only 3 engines ive ever owned that had head gasket issues
I guess I’ll let my friend know. He has a 2008 Durango with 180k I did the first oil change for him. I did 5W-30. The most recent oil change we did, we used 5W-20. The head gasket blew last year and we used some pour and go head gasket “sealer”. So far so good though.
Do your maintenance and dont overheat it wont be an issue. I thought my 4.7 was going to be an issue. Has never been opened up and has 250k miles on it. Burnouts all the time and full throttle everywhere I go. Trying to see how long itll go for. Because a 6.4 or possibly a 6.2 hemi is going into next
And yeah you see a lot of them because no matter how you treat them they won’t treat you good. You don’t see a whole lot of Chevy 350s and 5.3s in a shop but everyone knows both those motors are good. There were more Chevy trucks sold with a 350 or ls motor than dodge. It’s because the 4.7 isn’t that good
ford said the 5.4 3 valve was a great engine, gm said the 5.7 diesel was a great engine, the 2.7 was a great engine- all junk so is the 4.7 dodge engine
Junk. Drop valve seats, blow head gaskets, eat oil pumps .They had a run of 14 years, sb mopar went well over 40 years.Lousy power for displacement and for the technology, 1957 Chevy 283 had better power for displacement numbers. Prepare to put an oil pump in them every 100k miles of replace the whole engine at 130k.
The 4.7 is not a, “really good engine” from the factory no matter how much you take care of it, it’ll still let rocker arms/ roller followers loose in the head and drop a valve. The 5.4 3v is even better than that motor. At least frequaently changing the oil so the smal ports don’t get clogged in the 5.4 will make it last
Hahahaha NO it won't dude. Once the cam phasers start to go on the 5.4, the cam stops getting good oil pressure and the cam journals/caps and where the cam rides I the head get TORN THE FUCK UP in NO time. There isn't a way to fix the Ford without permanently removing the VVT, which kills mpg and power. And even then, you still have a VERY sensiting oiling system and NEED oil changes every 3k miles no matter what, to save those delicate fucking heads.... at least u can fix a Chrysler engine by installing better valve seats! 😄😄
I work at a machine shop also... I see this shit day in and day out. 3L3E heads NEVER come in as useable cores. Chrysler heads, on the other hand, are usually salvageable. The ONLY problem we see with the 4.7 Chrysler head is with the RIGHT head; when a seat drops, it spits a rocker arm out and in the process it usually breaks the "boss" that the rocker arm bolts to, ruining the head. But that's much less common than finding a completely junk 5.4 three valve head due to lack of lubrication. And it isn't even necessarily the phasers that cause this issue; ALL Ford modular engines, from 1990-1991 through the end of the run in the 2010s, had EXTREMELY sensitive oiling systems that had EXTREMELY poor oil filtering capabilities..... TONS of 4.6, 4.6 PI, 5.4, 5.4 PI, 4.6 three valve, 5.4 three valve, 6.8,6.8 PI and 6.8 three valve heads are unable to be reused during a rebuild because lack of lubrication (due to cam phasers being worn out, debris in the oil from cam phasers OR WHATEVER on non-VVT engines, and debris in the oil from the stupid ass plastic timing guide cassettes shredding themselves over time) destroying the cam cylinder head where the cam rides, the cam journals and cam caps..... it is a STUPID, STUPID design on an otherwise EXCELLENT engine (and by EXCELLENT, I am referring to the 4.6 two valve engine; the ONLY good (RELIABLE) engine Ford has made in the last 30-40 years.

Nice. Same here. Changed to detroit rear and other small various things. At 270,000 and no smoking..never left me stuck or dead in winter and pulled everything iv thrown at it., will def be maintaing the midsize dakota..
I approve. 267,600 on my lil rhino. Still pullin strong. But will have you listed for when/if the time comes.
I've had over 20 vehicles in my life, and my 2000 Grand Cherokee is the one I've had the longest for the most miles. 249k and still running strong, never an issue. And yes, It IS better then a Jeep 4.0 which I had before. The only issue is if you over heat them. Iron block + alum heads. Not really the engines fault. Owners not doing proper maintenance or pulling over if a problem comes up. Easy to work on, plenty of power, silk smooth.
I have a 2011 Ram 1500 since new and just hit 217,000km (135k miles) and just developed a wicked ticking in the top end, which is really loud at cold start but quiets right down after it heats up (about 15 mins). Could be failed lash adjusters or valve seats, both known issues with this motor. Will be looking into your motors and shipping to Canada.
Do you have the v6?
@@daddymilk4015 the 4.7 Powertech. But the issue isn't the engine; it's the coding for the MOPAR ECUs.
I have a 2008 3.7 L V6 Dodge dakota RWD Quad Cab with 67000 miles. Change oil every 3K miles with on sale Syn blend (phillips 66) or Conv oil (shell or penzoil or Quaker). Set the cruise at 70 MPH get 20 MPG. All around driving 17 MPG. 15 city. Wished gas mileage was a little better but it has been a good running engine. Keep the oil clean. But I live in Kansas so it is dusty.
I'm on 76k do oil at 10k max highway use only and it's running like new
i bought a 2008 dodge ram 1500 with a 4.7 in it. I see on the engine that its a 2010 4.7 and its almost at 200k on the odometer. Im not sure when the engine was replaced but it has no engine lights and runs great.
Sadly in 08-2011 the 4.7 was redesigned and produced between 290-302hp and 330ft/lbs compared to 235hp and 295ft/lbs for 1999-2007 4.7L
Oh my bad I miss read your text I thought it said a 2000 model engine replacement
Have a 2003 Durango SXT that I bought with 140,000 miles and I love it. Put new spark plugs, need to buy a new throttle body and wanting to buy a better cam cause the stock one isn't very good
I have a 2006 Ram 1500 and it has 246k miles and still going. I think I have a valve issue, but hey, with that many miles....no complaints.
I have a 2008 dodge ram with a 4.7 v8 in it but after some research it has a either a newer 2010 4.7 or a rebuilt engine with 2010 parts. not sure as I have not dug into internals. but it runs great with 187k miles on it.
The updated version came out in 2008, before the next generation of RAM trucks came out. So you most likely have the original 310hp engine that came in the 2008 model, unlike the 2007 and earlier which had the older 4.7 generation.
I bought an 07 Mitsubishi Raider with 222925 miles on the 3.7 for $2000. Very decent ride.
I have a 2008 1500 with the 3.7l she’s got 226000 on her and just started burning oil. The only thing I’ve changed so far is the water pump. This engine is a work horse. Would love to put a 4.7 for more power but don’t know how to go about it
Shitty lash adjusters, and the seats if they are overheated. I bought my 04 4.7 HO Grand Cherokee cheap ($500) because of a popped rocker due to a lash adjuster. Put rebuilt heads on it with solid lash adjusters, almost 200,000 miles and runs excellent.
I agree it is nowhere near as bad as the 5.4. I am a Mopar guy. But the valve seat issue was there from 99 to 07. Only the dual plug heads are immune to valve seats dropping. And the rocker arm usually comes out when the seat drops. So IDK what we are arguing about...hahaha
Have a good one
Awesome I have a 2011 3.7 so good news ???
I'm thinking Powertrain for my WJ 01 4.7-4.7HO update. My current engine #2 is still running clean, clean only 118,000 on it. But I've got the money and more horsepower reliably is ideal. Would I blow it? I wouldn't go that far. But the 4.7-4.7HO is sounding like the route.
So ill say this. I Drive ALOT. My commuter car is a vw tdi with 405k. Many years ago. I made my first big boy purchase, a low mileage 2008 ram with a 3.7. All it needed to do was haul a fourwheeler and go out on dates ( it was just clean and pretty all its life) and then i grew older and the toys and work life got bigger. That 3.7 lived off the rev limiter. Just of 2 years ago, i sold the truck in beautiful shape. An original 3.7 that was worked its a$$ off, purred like a kitten, didnt burn a drop of oil, didnt drip any fluids, with 380thousand relentless teenager style driven miles.
The old man still drives that truck with a smile. And i oughtta kiss that truck because ive assumed all these years that the 3.7 was actually a bad engine and i was just blessed.
Maybe still the case now. I have a jeep liberty with a 3.7 with only 180k. Does have its obvious leaks i gotta fix. But it sounds and runs solid.
I think the 3.7 and 4.7 are just those motors they really performed and lasted pretty well and got a bad rep from the small select numbers of bad individuals, all whole 300+ thousand mile vehicles wjth these engines... well people arent praising and yelling about the fact. Theyre just living life.
The second and third gens are pretty reliable, just keep up with the maintenance. Got 77,000 on my 06 Dodge Dakota with the 4.7
i have a 2005 dodge ram 1500, with a 3.7 Magnum engine that needs replacing. what would be a compatible upgrade
Bought a RAM 1500 truck with the 3.7 in it at 53K. it now has 80K on it, so I don't consider mileage like that to be any kind of test. When it hits 150K with just maintenance issues, I'll say something sweet. Til then, it's doing what I expected - runs like a sewing machine.
My 05 GC WK has 200k on the clock, on all original equipment. Change your oil every 3-5k miles, use synthetic or blends for the oil, not the old dino only stuff. Don't baby the engine, the engine needs to be put through its rpm band every now and then. And if you are 120k+ on your miles and still rocking the factory Rad, replace it. They are time bomb and if it fails in a bad way, your engine is toast. They do not like to be over heated. Overheating this engine is pretty much death for it. The Waterpumps need to be replaced as well, they do fail.
on my 3rd water pump, replaced waterpump and rad @ 170k miles. Now pushing 200k miles and thing runs like a champ. We put around 2-4k miles on it every month. It has never left us stranded.
Like all Powertech Engines at this age, my Valve Covers leak. That and the Exhaust Manifold bolts breaking are two nearly guaranteed problems you will face at some point owning these things.
The 545RFE is bulletproof.
My GM car's never had as easy as life as my jeep.
My old Jimmy went through two transmission rebuilds and a ton of engine components(damn spider injector), as well as a rear diff. Not to mention the crap suspension. She still lasted to 250k before getting rid of her, but still the cost of doing 250k was not cheap. The person who bought if from me had gotten a truck that was nearly half new.
My 3.7 has been through 4+ water pumps, 2 rads, 3+ thermostats, overheated at least 5 times. 180,000 miles and it still runs great.
Original owner of 04 ram 1500 with 3.7 with 190k construction sight truck. Batteries,tires,oil(not as much as i should),air filter,pcv,2 pilot bearings and just put in 3rd set of plugs but they still looked like new.Replacing valve cover seals this weekend(starting to weep).That's it! I have been getting nervous because this truck has never stopped.I somehow feel better knowing I am on borrowed time with the water pump.How long will the "lifetime" timing chain last?
@@gueto70 The timing chain will technically last the life of the engine. There's no recommend change interval and very few cases of failure. The key to it's longevity is lubrication. Dirty oil and long change intervals may cause accelerated wear of the chains and tensioners.
@@xc8487 thanks for reply.My truck is having a pessimistic mid life crisis. Truck has worked hard its hole life with no complaints.finishing the last of the suspension,bearing hubs and drive shaft replacements this weekend.planned on replacing lifters next.All the factory parts were good just preventative.never herd of the water pump problem.on my list.
Lost compression on no. 5 cylinder. Engine runs really rough. I'm told the cost to fix is worth more than the truck. What does the reman engine cost?
so I got a 2000 Jeep Grand Cherokee with a 4.7 and I love the motor I was wondering if anybody has the 3.6 and if it's as durable because I was looking to buy a newer one and the 3.6 seems to be more, nowadays anybody got comments or suggestions
I love my 3.7 L v6 in my dodge nitro 💯
Had one in an '07 Dakota and it surprised me! It would outrun all the late 90's v8 trucks
3.7 junk
@@dwrldgster3151 😂😂😂 never had any problems and it’s paid for... either way I have 2 other cars..
Lol, I have a 2010 Dodge Nitro with 285,000 on it. Yeah it burns a little oil, but I have a saying when it comes to this car, and that is “there’s 3 things in life you can rest assured on; death, taxes, and the nitro is gonna start in the morning.” The 3.7 and 4.7 are my favorite for the reliability hands down.
Not that he needs any help selling engines ( He's a very good salesman ) But I have about 205,000 on mine and the only issue I have is bad exhaust manifolds. And its actually not all that bad of a job, on the 05 Dakota's anyway. Plenty of room through the wheel wells. The reason the engines drop seats is because people don't realize there is a bleeder screw up top for the cooling system and it 100% must be done every time the coolant is drained for any reason; it must be blead! And for a good period of time, up to 40 minutes in some cases with the heater blowing. Or else bubbles in the system lead to un-even cooling and hot spots in the heads and POP goes the valve seats. The other problem is the rockers(can)fall out due to bad lifer/ "lash adjuster-springs" basically you only need the valve covers off, and from that point on its a matter of just poping the rocker arms off (a plastic clip remover, for autobody will do) Anywho, if you take care of that before there is a problem.. There WONT be a problem. They're good little engines, I'm even considering getting a second one for my 80's dodge that has a manual transmission.. (: (edit: I'm talking about the 4.7 Magnum specifically)
I have an 07 Liberty with 3.7 it has over 315,000 on-the-clock it's an amazing little tank of a vehicle but now I also have a 03 4.7 L in a Ram 1500 and the motor has been ripped out and rebuilt twice and it keeps blowing head gasket I honestly I'm just disgusted with this 4.7 L and I don't know if there's any help for it I'm considering ripping it out and putting a 5.7 in it
I got 140,000 miles out of my 3.7 without any issues before I sold it. My only complaint is the oil filter location. Pain to do oil changes. The 3.7 also has pretty loud valve-train clacking. My biggest issue with Chrysler is their transmissions. The 42RLE was a piece of garbage.
Don't forget the Dodge Nitro started in 2007 and it has the 3.7 Liter. I have one with 167,000 miles!
I have an 08 nitro with 141k miles you have any problems with it?
@@chrisohlandt4275 No I didn’t, do your regular maintenance and drive it right and it should last a while it’s basically a Jeep Lol I sold it to my niece 6 months ago I really liked it in the 5 years I owned it. and no warning ⚠️ lights
@@glanphear588 ok awesome thank you
@@chrisohlandt4275 you’re definitely welcome
Be careful theres some/many that also have the 3.9 I beleive? But its a timing belt motor.
I'm almost 200k miles and for maintenance reasons I'm replacing the lash adjusters and timing chains along with a few other parts. Maintenance is key, I really love my SW 4x4 02 Ram truck and the rowdy little 4.7 in it and when I die, bury me in it!
my friend has a 2004 Dodge1500 with a 4.7 pickup with 130k miles and used royal purple oil since new and serviced cooling system alot and it still blew the head gasket and is blowing plenty white smoke and can't afford to go buy a new truck. another friend had a 99 intrepid and that motor died at 73k and he changed oil. same thing with my daughters 2001 intrepid 2.7 motor died at 101k miles. then she got a 2011 durango (I told her not to) and had to change the cam and lifters at 153k and the transmission at 157k then dumped it.
The seats never get loose 😂 the valves bend. And hammer the seat till it falls out. Check the run out on the exhaust valves, also look at the exhaust valve springs on the 3.7l with the external shroud
Keep up the maintenance and don't drive like every stop light is the Christmas tree at the winter nationals!
I have a 2007 with 220k think head gasket is leaking 6sp manual also.. I'll fix lt 😅
Liberty or Ram
I have one of the 4.7s in my 2013 ram, I got the truck for a STEAL! It’s been a good engine I had an issue with the electronic throttle body but other than that it’s been pretty good, this engine does seem to have serious power loss at high altitudes though, anything over 5k feet it sounds like it’s gasping for air and has no power.
Same, I got my 2009 for a steal. It's been a great engine going on 180K miles now.
Mine has 260,000 on it. All orig. still goes well.
Craig Moorer what car
So does mine, in a 2004 jeep liberty
The engines were fine with synthetic fluid. It was their cooling system that had issues.
That's what I've read. Another issue is they used single row radiators, so they didn't have as much cooling capacity as they really should have had, they bare minimum'd it. I'm pre-emptively doing a motor refresh on my 4.7, got the heads rebuilt, replacing all the seals, oil pump, water pump, etc. and will also be putting in an upgraded all aluminum (no plastic caps) 4 row radiator. Also swapping out that goofy hydraulic cooling fan for an electric setup.
If only you guys replaced those seats with actual hardened iron ones instead of powered.. and if only you put cast or forged rods in them instead of those ticking time bombs called powdered metal connecting rods.. Why anyone thinks those things are a good idea is beyond me, old school cast iron rods are stronger.
How much for a 4.7 h.0 and how can I order one
I have a 2013 Chrysler 300s 3.7. Is this the original motor? I'm not finding information that matches.
2013 didn't come with the 3.7. You have a 3.6. 3.7 never came in a 300.
Have a 03 ram 1500 4.7 L 2wd 180,000 miles motor and transmission are perfect hoses water pump and plugs and coils. Oh and a fuel pump is all that was done nothing major @ all
So how much do one of them cost??
Great video! Thanks!
2003 Liberty 3.7 right head destroyed #2 cyllinder head dropped valve seat. Full Synthetic since birth. Last one for me !
2002 Liberty 250K no problems
will any 3.7 Chrysler engine fit in a 2004 dodge ram 1500 that had a 3.7
A 454 will fit in a chevette so,,,, sure! The closer the too vehicles are the easier the swap.If the only difference is the name stamped on top not bad.pulling a transverse mounted automatic to bolt up to a in line manual,from a different gen that's more work.
Same same bro
I was a salvage dealer and buyer and by far these trucks with this 4.7 are # 1 in salvage sales and facebook with bad engines. to say these are ok is like saying the F-150 5.4 3 valve is a great engine. not until 2009 is when they corrected some of these issues. but this dude is a salesman.
Y'all can say whatever you want,2002 jeep liberty, always something.youve got to know that engine and like to work on em.
My 02 ram 4.7 has 180,000 miles have had no problems except for it consumes about 1 quart of oil every 1,000 miles. Smokes on start and very little when driving. Thinking piston rings are worn out. What do y’all think
just looked at buying an '05 Ram with the 4.7 earlier today, took it on a test drive and it ran and sounded good but man was it a dog when i went to accelerate. which is unfortunate because i really did like the truck, but if it seems sluggish on its own then i cant imagine how it would be towing something.
Is the 4.7 a good engine to run 10 pounds of boost through
@Rusty Highlander NO! any boost on a stock 3.7 or 4.7 could destroy the pistons because the top compression ring is very close to the top of the piston and can get very hot and expand too much under boost. You can buy forged low compression pistons tho, then i bet it would be a pretty solid boosted v8.
I run 5psi through mine, wouldn't go any higher though.
i need a price on a rebuilt for my 2002 jeep liberty 3.7
How much for a 4.7
Very nice video!
forgot to talk about the timing chain or the head gaskets
I have a 2006 Jeep commander with a 4.7 engine that I just removed. I need to reinstall another 4.7 does the year matter
No
Yes, it does.
Then why are they so expensive?
The 4.7 is a dual over head cam. Not a single. And Has many problems right out of warranty.
does the 3.7 have the EXTREMELY bad head design like the 4.7..... before anyone argues look in the used market and see how many very very nice rams and jeeps that are dirt cheap with dead 4.7.... ive owned 3. they are now the only 3 engines ive ever owned that had head gasket issues
These two engines 3.7 and 4.7 has to have 5w30 full synthetic motor oil. If not the valve seats will come out by 75 to 90,000 miles
Castrol GTX Ultraclean synthetic blend. 06' ram 4.7 275,000 still pulls super strong
I guess I’ll let my friend know. He has a 2008 Durango with 180k I did the first oil change for him. I did 5W-30. The most recent oil change we did, we used 5W-20. The head gasket blew last year and we used some pour and go head gasket “sealer”. So far so good though.
Are you all related to FRASER ENGINES?
valve seats dropping all over the place lol better change the oil in the 3.7 and 4.7 junk
Do your maintenance and dont overheat it wont be an issue. I thought my 4.7 was going to be an issue. Has never been opened up and has 250k miles on it. Burnouts all the time and full throttle everywhere I go. Trying to see how long itll go for. Because a 6.4 or possibly a 6.2 hemi is going into next
@@MrMuffanga My 4.7 HO dropped the seats anyway....Still love it though :)
Just got an 02 ram 1500 with 119 k runs fine just weak as hell
It might have a 'highway' gear in the rear diff.
And yeah you see a lot of them because no matter how you treat them they won’t treat you good. You don’t see a whole lot of Chevy 350s and 5.3s in a shop but everyone knows both those motors are good. There were more Chevy trucks sold with a 350 or ls motor than dodge. It’s because the 4.7 isn’t that good
oh just a valve seat..no big deal... if it fails 6k no huff...
ford said the 5.4 3 valve was a great engine, gm said the 5.7 diesel was a great engine, the 2.7 was a great engine- all junk so is the 4.7 dodge engine
Compared to the old iron block and iron head motors, I would agree as far as reliability.
4.7 junk sludge bomb
Junk. Drop valve seats, blow head gaskets, eat oil pumps .They had a run of 14 years, sb mopar went well over 40 years.Lousy power for displacement and for the technology, 1957 Chevy 283 had better power for displacement numbers. Prepare to put an oil pump in them every 100k miles of replace the whole engine at 130k.
3.7 engine
lol only been around 15 years! small block chevrolet. 1955 to 2000.
spend 5k for a truck thats worth 1500
The 4.7 is not a, “really good engine” from the factory no matter how much you take care of it, it’ll still let rocker arms/ roller followers loose in the head and drop a valve. The 5.4 3v is even better than that motor. At least frequaently changing the oil so the smal ports don’t get clogged in the 5.4 will make it last
Hahahaha NO it won't dude. Once the cam phasers start to go on the 5.4, the cam stops getting good oil pressure and the cam journals/caps and where the cam rides I the head get TORN THE FUCK UP in NO time. There isn't a way to fix the Ford without permanently removing the VVT, which kills mpg and power. And even then, you still have a VERY sensiting oiling system and NEED oil changes every 3k miles no matter what, to save those delicate fucking heads.... at least u can fix a Chrysler engine by installing better valve seats!
😄😄
I work at a machine shop also...
I see this shit day in and day out. 3L3E heads NEVER come in as useable cores. Chrysler heads, on the other hand, are usually salvageable. The ONLY problem we see with the 4.7 Chrysler head is with the RIGHT head; when a seat drops, it spits a rocker arm out and in the process it usually breaks the "boss" that the rocker arm bolts to, ruining the head. But that's much less common than finding a completely junk 5.4 three valve head due to lack of lubrication. And it isn't even necessarily the phasers that cause this issue; ALL Ford modular engines, from 1990-1991 through the end of the run in the 2010s, had EXTREMELY sensitive oiling systems that had EXTREMELY poor oil filtering capabilities..... TONS of 4.6, 4.6 PI, 5.4, 5.4 PI, 4.6 three valve, 5.4 three valve, 6.8,6.8 PI and 6.8 three valve heads are unable to be reused during a rebuild because lack of lubrication (due to cam phasers being worn out, debris in the oil from cam phasers OR WHATEVER on non-VVT engines, and debris in the oil from the stupid ass plastic timing guide cassettes shredding themselves over time) destroying the cam cylinder head where the cam rides, the cam journals and cam caps..... it is a STUPID, STUPID design on an otherwise EXCELLENT engine (and by EXCELLENT, I am referring to the 4.6 two valve engine; the ONLY good (RELIABLE) engine Ford has made in the last 30-40 years.
Advantage Recovery I’m not even gonna bother with you you’re too far gone😂 I’ll just not waste 20 min of my life typing paragraphs of bullshit you googled
dodge is the spit at the bottom of the barrel junk all of them except the old school mopar
Which is why so many of their trucks are still on the road while Toyotas rust out and Ford and Chevy are just dogs.
My neighbor is selling his 2012 Jeep Liberty with 190k mi. with the 3.7 for 1000 bucks, seems like a lot of vehicle for the money.
