I am a certified Detroit Diesel tech and work on these every day. The major issues depend on which generation you have. Epa 07 I am not too familiar with. Epa 10, oil leaks on rear structure, head gasket, cam housing, injection Pump, air compressor, oil pan, oil coolant module, Aftertreatment issues. Injector issues GHG 14, probably the best DD engine they built. Oil leaks are the same on every engine. Injector issues, can cause backward running engines. GHG17. Metal in fuel/Injection Pump grenading. Head gaskets leaking, wrist pins coming apart, one-box issues. Gen 5/GHG21. The absolute worst engine Detroit has ever put their name on. Liner o-rings fail causing coolant to leak out of headgaskets. Head gasket oil leaks, the overhead adjustment needs done several times before 100k miles or you will drop a valve bridge, bypassing oil passages, engines majorly failing before 10k miles. I've seen 1 with 675 miles on it drop a valve, just rebuilt an 8100 mile engine that broke an oil ring. Those are the most common issues I have seen. I would stay with the GHG14 engines, 17s are not terrible but not great, avoid Gen 5 like the plague.
@Eduardo Sandoval GHG14 is 2014-2016 I think even some 2013's were GHG14 as well. Detroit typically comes out with the new engine 1 year before the EPA required Date.
@dguido1000 no. Gen 5 cane out in 2020/2021. Easiest was to tell if you have a Gen 5 or ghg17 engine is to look at the fuel system, intake manifold, egr cooler, or one box. The ghg 17 intake manifold is mire square than the Gen 5. Ghg 17 high pressure fuel rail supply lines stick straight up on the rail, on a Gen 5 they are angled. Those are the easiest. GHG 17 engines are good engines, but they have their problems too. I will say that Detroit is finally starting to fix a lot of the Gen 5 issues. I'd you do get a Gen 5, get a late 22 or 23 truck.
@@Mopars_41 ok thanks my budget has me staying at a 2019 model..there’s one with 494k on the miles ..would you recommend that I usually run the Volvo d13
I drove dd15 since 2017 some older and some newer models and never had issues with any of them. They were in shop only for maintenance and of course emissions BS
Our fleet has had five high pressure fuel pump failures. From 2015-2018 year models, but the 2017-2018s seem to be more problematic than the older ones. So far the failures have all been between 300-350,000 miles. First warning will be a knocking sound or tapping noise at idle that almost sounds like a burnt exhaust valve. You’ll also see super fine metallic shavings that look like grey sand in the bottom of the fuel filter housing and even on top of the filter cartridge itself. As the pump continues to disintegrate you’ll notice a loss of power and sluggish throttle response, particularly under a heavy load. The fix is “simply” replacing the high pressure fuel pump. The pump alone is around $1,800 last time we had to buy one. If not under warranty, the total cost is about $7,000 (US) because basically the entire fuel system has to be replaced. Not just the pump but also the lines, injectors, etc. And no, you will not get any warning lights with this failure.
so i just got a 2016 dd15ni should replace all the fuel system asap to avoid break down and costing an engine right like they say an an ounce of prevention is better then a pound of problems. or something like that. Larry B
@@larrybroad8746 : if you are still covered under the warranty you might be able to talk the dealer into it. Otherwise I think I’d take my chances. From my experience you’ll get a warning before it dies completely. I was able to drive mine another 60 miles to the shop after it started making a noise like a burnt valve, and the other drivers here had similar time before it quit.
That doesn't make sense if the HP pump is failing as its after the filtration unit so no evidence will be seen in filter so if your seeing this contamination it could be related to why your getting the failure not from it !
Coolant leaks has been a problem. Not so much because of gaskets or seals rather cause of sloppy manufacture don’t tighten bolts. Same thing with diesel fuel lines
The DD15 is a great motor with 2 exceptions; the emissions systems (horrible for all diesels) and Detroit used WAY TOO MANY plastic parts that frequently break, hence why I bought a '99 build CAT, though I considered a 60 series
Idle is the biggest reason for carbon build up,so get an APU and problem solved!😁Any diesel engine, not just DD15!About the o-rinngs on the pick up tubes, I think one off the reasons for them going bad is extended oil changes,wich turn the rubber into plastic.Great video!🙂
Exhaust gas recirculation has never reduced emissions. It tests cleaner. EGR is a favorite malicious prank of many government departments. Closing the control valve or blocking the flow shuts down the exhaust. The motor perks up and runs better in every way.
@King Of Crunk I have run both vehicles and I hate the smell of def when it regenerates. It's a horrid smell and if you are indoors both will kill you. I would not recomend ether. And the dpf gets as hot as a barbeque and can clog easily if not run enough to regen or forced regen. I'll take my old engines any day.
@King Of Crunk I've done the self regen on pick up and semi. Not a fan of ether. Take the older engine over all that crap. I don't care the year and when it runs.
Re: cheap engine oil. I was a placer miner for years. Large dozers, excavators, water pumps, loaders. We bought our oil at Walmart - by the pallet. Why ? Walmart does not make oil - they send out tenders and oil companies make the oil. Never an issue we could point to being oil related. Change every 250 hours.
Exactly. Walmart has to have a good reputation, think that plays into oil and batteries too. They have to good ratings too, like dexOS rating, you like you say, it's got to be a big name making it. Been using it for years, even been pushing my engines even over 200,000 with no problems.
My truck has a diagnostics tool on board. Different than just codes and tells me all I need to know from what the computer is seeing. I have computer scanner as well. Though so far have had no need for it. Series 60 without all the emissions crap. I'll take that engine and truck any day over all this new stuff. Last thing I changed was an oil coolant level sensor. Takes about 5 minutes to changed it and its working great again. I am not a certified mechanic. Though I know my way around a truck for most things and can do most the jobs that are needed on it. I keep learning and that is key here. I will build a shop to be able to take the truck apart and put it back together again. Then I'll know most of what I need to. I enjoy working on my own equipment and learning how to fix and maintain it.
Definitely don’t forget about the exhaust leak I have been in the shop 6 times for the exhaust clamp into one box and just last week had an exhaust leak by turbo the bellow flex pipe I’m only at 46k miles 2022 gen v dd15 505 hp 🤦🏽♂️ if the truck gets one more exhaust leak I’m about ready to throw this truck in the trash 🗑
Make sure to adjust intake valves periodically, the clearance between the rocker arm and valve stem will diminish. You can immediately tell when cranking to start or rough idling. Cause intake valves are not sealing compression.
I'm a mechanic and at my company they have cascadias with detroits and kenworths with cummins and all the Detroits (dd15) have oil leaks hahaha even the brand new ones have oil leaks because of the oil pan gasket, rear main seal, oil pan drain most commonly
@@Freightlinerbob run it at around 1000 rpm. In the ECM you have to have the idle shutdown timer turned off, idle rpm turned up and the Auto Elevate feature turned on so the truck can regen while it’s idling.
@@christianb9565 that’s what I’ve been doing. This is my first winter with a modern motor and it’s also been very cold. Much colder that usual for where I operate. I’m actually shocked at my idle time. Hearing that regen in the middle of the night makes me wonder how much life I’m taking out of the motor and DPF.
@@Freightlinerbob For heat, the most efficient and popular way is to have a diesel fired Wabco/Espar bunk heater installed, and if you're ordering a new truck, you can order it as a factory installed option.
wow. Charlie, your puppy. The first guy, which gave me the opportunity to learn trucking; his name was Charlie, as well ! 1977-78, Kenworth cabover, 350 engine, 13 speed, I went on to buy a Mack B-75, triplex tranny. Next was a Freightliner COE, cummins, 13 speed. Take care, stay warm, Mr ET......don't get beamed up,.....just yet.......
Have a 2011 DD 13 that cranks upon priming and then hydrolocs. Any ideas? It has new injectors. We are thinking its the pressure relief valve on the fuel rail.
Some professional workshops are not doing a good job and are dishonest about the work they’ve done. Failure to replace filters, using cheap low grade oil. Some workshops are so brazen that they openly admit that they don’t carry out all the maintenance work as required by the manufacturer.
The fix for cold temperature 🤒 for the DD15 or the DD16 Driver's should invest into a FASS fuel system with heater it will prevent your diesel ⛽ fuel from gelling over will increase reliability and fuel mileage
That heater won’t do anything to keep fuel from gelling in the tank. It only heats at the filter head and only if the ignition key is on which likely means the truck is idling or in the case of the coolant heater, the truck must be idling. When an engine is idling, fuel is being circulated and heated up without any help from any outside source. Especially that little heater element in the FASS system. That FASS system must be prone to gelling or icing since it’s hanging out there off the frame rail and not on the side of the nice warm engine like the OEM filters.
@@Freightlinerbob Agree, APU with tank heaters, then OEM Fuel filtration with heaters. Some newer engine designs do not return as much fuel to the tanks, as the older ones, this can lead to fuel gelling, in bad conditions. Best wishes from 55.75N
My truck had same issue with oil pressure and i lost the engine and now am looking for engine I didn’t get any check engine light or anything its just shut off in the medal of the road man what a night
Charlie distracted me. He’s very cute! I thought EGR problems were a thing of the past with these latest trucks, obviously not at Detroit. Lots of love Brian and Charlie!
For oil it is the API rating. As long as the API is approved for that engine your good. Engine manufacturers also say never change the weight of the oil in the new engines, that they are engineered for a specific viscosity. I have been using Pittsburg Power’s catalyst and I have to say it’s expensive approx $18 per fill up but boy does it really cut down on carbon buildup. I also had a series 60 and yes it leaked as much as my AMF Harley Davidson. If you did not see some drippings better check the oil there may not be any to leak out. :-)
I am a Freightliner Parts Salesman..common issues..(1) leaking oil pan gaskets. Make sure to change the bolts w/the grommets. There is now a kit just for the grommets! (2) Oil leaks at the injection tubes to injectors...don't just change the gaskets at the injectors...replace the six injection tubes (they come with the gasket). (3) Oil leaks at the injector wiring that goes through the valve cover gasket (oil can travel through the front & rear harness and cause electrical disruption between injectors and ECM), (4) DPF issues do to extended idle times, note cleaning the DPF filters does not bring your DPF filters to 100%!!! Install new filters and you want have replace them as often! (5) DO NOT DELETE THE DEF SYSTEM, THE TRUCK WILL NEVER RUN CORRECTLY AGAIN, AND IF YOU GET CAUGHT THE FINES WILL BE STEEP! NOT TO MENTION NO FREIGHTLINER DEALER WILL EVER WORK ON YOUR TRUCK AGAIN UNTIL THE SYSTEM IS COMPLETELY REPAIRED TO OEM SPECS!
The oil leak in harnesses seems to only be an issue on extended service intervals and or with shit quality oil as its not the oil but the carbon concentration in the oil ie how black it gets that it becomes electrically conductive
I know this is about dd15 but we have a big fleet of dd13’s (various years of freightliner cascadias ) and we have yet ,knock in wood, have a fuel system failure. More specifically a fuel pump. Hell we have a 2014 with just of 700,000k miles and we JUST put a one box into it which was surprising because we’ve typically seen trucks need one boxes wayyyyyyy before 650,000
How are the dd13s in general? I just got one def and egr deleted and I’m scared of either the dd13 messing up or the Eaton ultrashift 10 speed auto messing up (it’s a 2013)
In 2015 I had 4 2010 western stars with DD15s. 2 of them dropped the oil pump pickup at 300k, 1 locked up. I recently got them fixed. I put series 60 14L in them! DD15 are junk!
I probably shouldn't say this...... But I work on Detroit diesels.... Oldest one I've worked on is the 6110s.. . I love all the two strokes.... . They just newer motors not so much...... I'm a class a trucker.. . John 48 state OTR...... More power to you brother..... Oh...... My father was a Novi....... My mother American........
U forgot to say that : that's u r main reason for black oil în such a short time , carbon build up on your piston etc ... is like shiting on your food , and eating it
Hello sir I have 2015 freightliner cascadia dd15 I have sign spn 102 fmi 18 I am in trouble I have change dpf one box Change new turbo all sensors all hoses but code still hav do you anything of this kind I already waste to much money Intake system derate 25%
My 2016 DD15 was squealing but only while driving and the sound of it goes up or down with the rpms - Took it to Freightliner - paid $300 for diagnosis - was told it was fan hub needing to be replaced - 2 days and $2900 dollars later for a 3.5 estimated job nothing was fixed ! The tech only test drove it in the parking lot - the squealing dosent show up until about 45 mph and I explained all this to them in the beginning I went back made them pull my old hub fan from the garage and give it back to me - now I am waiting till morning to see what their story is I am suspicious of a false diagnosis - its still squealing just as it did before I went to the dealership Tech mentioned a saturated belt but said they didn't have one snd recommended I get it replaced I am not paying $2900 over a sqeaky belt it thsts all it is. - I am going to take the old fan hub to a different shop snd see if they can yell me if its faulty or not This has been a terrible experience so far - Anither guy was waiting 5 days and they still haven't figured out what the problem is on his truck Maybe decriminalization of all drugs in Oregon was not the best thing since sliced bread idk but this is complete bull crap ! I am going to call my bank Monday and put a stop hold on the payment if Freightliner dosent come up with a solution worth $2900.00 very soon !!!
EGR valve, cooler, DPF will NEVER get better, you can BET ON IT! Also, you are mistaken regarding the amount of gases the EGR puts BACK into the engine... you said 10%, but it is more like 50%, 5X more!!!
I hate all this emission garbage. Killing engines for a feel good idea. Does all the def fluid, dpf and the rest of the emission bs not have an environmental impact? Or is this just like electric cars that they say are going to save the planet?
I think my 2011 dd15 is having a fuel quantity control valve. The engine seems to have a lope when it idles or like a surge. But no check engine light. Any thoughts? Truck only has approx 550k original miles.
I really wish I had this video back in 2016. I had a 2012 cascadia with a dd15. I made a left turn from a 2 lane to a 2 lane. oil dropped to 9 psi. (Scan gauge connected) No One could tell me. 2 months later I find out (with 3 Gal of Lucas in it) what's up. Do the tubes. 3 weeks later I am furious that I have oil in the water and water in the oil when at home . I had hit 73 psi on startup 3 days earlier. I thought I blew out the oil cooler. I cried. Filed Bankruptcy.End of ownership of a business. Don' ask. Suggestion. When you do the tubes at a REPUTABLE SHOP( Steer clear of empire in Mobile)have the O-Rings of oil cooler done too. Same material to seal.
i absolutely agree with you on the dd15. i have been truckin for 40 years the best most reliable engines are detroit diesel i have been runnin a 60 series for as long as i can remember never have i broke down and could not fix the problem easily love them like my wife can always count on them. Larry B
Lol!! I strongly disagree! Every time I've had a major breakdown, it's been a Detroit diesel. I switched to a cummins isx! And guess what?? I'm able to make money 💰 without usually spending tons of money on repairs! But to each his own
_But don’t forget you guys are operating in extreme freezing weather conditions, everything shrinks in those weather conditions, not to mention in those conditions your engines are going from extreme freezing to nearly 200° hot Engine and then rapidly back to freezing again, so what’s so coming up there may not be the same issue in the states with temperatures don’t reach below or minus degree weather nowhere near as often as in Canada_
Yep the so called cycles(every time your engine changes the temps so engine off to running engine) are as I heard somewhere on YT way more important than mileage. No wonder car engines wont last that long as truck engines, we put them thru way more cycels per mile than we do with big rigs. Add winter to it and it takes a huge shift of size in quick time from very cold engine that was off to running engine, like -20 C to + what, a 100 C? In like few minutes?
Puts more wear on the engine specially on older engines that use conventional oil because it gets thick and it takes way longer to start lubricating motor
_Use MotorKote oil over all competitions in your diesel engine, it is the only oil in the industry that is 100% anti-friction, it’s $100 a gallon but trust me it is an investment that is worth it._
Dd15, word to the wise replace serpentine belts and pulls every 2 years and water pump every 3. I do it as preventative maintenance, they are weak points.
DD 13 ,15 , and 16’s classic example of German over engineering . Germans are capable of over engineering a toothpick ! When the diagnostic light is illuminated , you know your engine is running !
It's the unfortunate issue with engine reviews on the internet. The valuable information is from the OEM'S themselves who have the real warranty data on hundreds of thousands of engines. The big fleets also can get some decent data once they have a few hundred trucks of each. The same goes with fuel economy... it's useless to use one person's value because there are too many variables at play. I'm an engineer who fixes these warranty issues.
I'm back in the day if you didn't see oil leaking out of a tractor with a series 60 Detroit there was something wrong the sky was going to fall or you owe the IRS a billion dollars or something because it was not normal for a series 60s not to leak oil something was wrong with that day🤣🤣🤣🤣🤣
Coming from a small company that had nothing but pre-emissions cats I think the DD 15 is a joke. We have a fleet of over 30 Cascadia’s all with DD engines we’ve had five of our trucks blow the glued on piece of plastic on the driver side of the oil suction manifold completely off and lose oil pressure instantly. The O-rings are one thing causing low oil pressure but the manifold breaking kills them instantly. After seeing four of our own trucks and two outside customers trucks with completely demolished engines the owner of our fleet decided to pull every truck he had in and replaced the suction manifold some of which had already had the O-rings replaced due to low oil pressure. That’s a lot of money to spend because of crappy plastic parts. These new DD engines are not real Detroit’s this is a Mercedes engine I don’t care where it’s built but it’s a rebranded Mercedes engine. I believe in other countries they call it a Mercedes SM 471 which you can actually see the 471 just beneath the valve cover on a DD engine you can look this up. We’ve had a lot of bad air compressors which are a pain in the ass to change especially on the shorter nose trucks which if you’re an owner operator that’s extra labor you’re paying for to get it replaced. Get an older truck fix it up and be happy. We’ve not had any major problems with oil leaks other than the little seals around the injector lines which isn’t a big deal and leaks around the crank case filter or separator. Aside from that the engines do OK if one of the petty problems doesn’t kill it first. I consistently see owner operators with older trucks that they have practically rebuilt giving way better service than some of these newer ones with all the electrical and emissions nightmares not to mention the automatic transmissions when they go haywire. Honestly don’t see how owner operators afford to keep these things on the road. Debonded hoods the glue that holds the top of the truck together coming loose leaking windshields Frieghtliner actually put a plastic gutter type thing over the fuse box so when the cab leaks it doesn’t kill the sam cabin. I have learned to hate these trucks even though I know they’re nice and comfortable and do a good job when they’re working right but they are super poor quality everything is cheap. I had a owner of another trucking company explain to me why he would spend 50 grand on a high mileage Peterbilt or Kenworth and then take a gamble on how long it would run before he had to rebuild the engine or replace a transmission or drive axle and he said because if I keep good service records on these trucks and keep them looking good I can turn around and sell it and get back what I have in it and he’s exactly right and I’ve seen him do it for years. His early 2000s model peterbiults and Kenworth all with cat engines give better service than 80% of our newer cascadias. The interiors and cab definitely hold up way better
i went from owning 12 379" s with cats to all cascadias. fuel went from 4.5-5.5 to 7.5-9mpg. it would cost me 40-50k a year per truck in repairs. just traded in my 2019"s and got my new 2023"s. when you own your own trucks you will think different. you guys must all be horrible drivers or something to be destroying them. don't believe all the bs they tell you. put 80k on a 22 year old truck then 35k on a platinum caterpillar rebuilt then tell me how great it is ..

I'm a mechanic and at my company they have cascadias with detroits and kenworths with cummins and all the Detroits (dd15) have oil leaks hahaha even the brand new ones have oil leaks because of the oil pan gasket, rear main seal, oil pan drain most commonly
It's 2022 and we still can't figure out how to keep fluids from leaking
How cold does it have to be before you idle the truck all night and how bad is it for the motor? Particularly the DD15
You should never idle your engine, other than a few minutes at start up, to warm up, and a few minutes at shutdown, to cool down.
@@RealJohnWayne yeah I know. But what do you do when it’s actually-30 Celsius or colder?
@@Freightlinerbob run it at around 1000 rpm. In the ECM you have to have the idle shutdown timer turned off, idle rpm turned up and the Auto Elevate feature turned on so the truck can regen while it’s idling.
@@christianb9565 that’s what I’ve been doing. This is my first winter with a modern motor and it’s also been very cold. Much colder that usual for where I operate. I’m actually shocked at my idle time. Hearing that regen in the middle of the night makes me wonder how much life I’m taking out of the motor and DPF.
@@Freightlinerbob
For heat, the most efficient and popular way is to have a diesel fired Wabco/Espar bunk heater installed, and if you're ordering a new truck, you can order it as a factory installed option.
My Series 60.on my Prevost has no leaks that I can see. I heard the two strokes leaked a lot more.
wow. Charlie, your puppy. The first guy, which gave me the opportunity to learn trucking; his name was Charlie, as well ! 1977-78, Kenworth cabover, 350 engine, 13 speed, I went on to buy a Mack B-75, triplex tranny. Next was a Freightliner COE, cummins, 13 speed. Take care, stay warm, Mr ET......don't get beamed up,.....just yet.......
Have a 2011 DD 13 that cranks upon priming and then hydrolocs. Any ideas? It has new injectors. We are thinking its the pressure relief valve on the fuel rail.
Might just be best to take that in to a mechanic to be honest
Some professional workshops are not doing a good job and are dishonest about the work they’ve done. Failure to replace filters, using cheap low grade oil. Some workshops are so brazen that they openly admit that they don’t carry out all the maintenance work as required by the manufacturer.
The fix for cold temperature 🤒 for the DD15 or the DD16
Driver's should invest into a FASS fuel system with heater it will prevent your diesel ⛽ fuel from gelling over will increase reliability and fuel mileage
That heater won’t do anything to keep fuel from gelling in the tank. It only heats at the filter head and only if the ignition key is on which likely means the truck is idling or in the case of the coolant heater, the truck must be idling. When an engine is idling, fuel is being circulated and heated up without any help from any outside source. Especially that little heater element in the FASS system.
That FASS system must be prone to gelling or icing since it’s hanging out there off the frame rail and not on the side of the nice warm engine like the OEM filters.
@@Freightlinerbob Agree, APU with tank heaters, then OEM Fuel filtration with heaters. Some newer engine designs do not return as much fuel to the tanks, as the older ones, this can lead to fuel gelling, in bad conditions.

2019 cascadia water got in ecm plug had to change ecm and wire harness twice !!!
And I thought my old 1971 Detroit Diesel
871 was a dripper. My 1978 DD 353 really Leaks. This makes me feel better.
My truck had same issue with oil pressure and i lost the engine and now am looking for engine I didn’t get any check engine light or anything its just shut off in the medal of the road man what a night
Yikes
Freightliner diesel tech here. 3:59 were randomly looking at the one box DPF filter clamps and seals while we’re talking about oil leaks 😂
Charlie distracted me. He’s very cute!
I thought EGR problems were a thing of the past with these latest trucks, obviously not at Detroit.
Lots of love Brian and Charlie!
For oil it is the API rating. As long as the API is approved for that engine your good. Engine manufacturers also say never change the weight of the oil in the new engines, that they are engineered for a specific viscosity. I have been using Pittsburg Power’s catalyst and I have to say it’s expensive approx $18 per fill up but boy does it really cut down on carbon buildup. I also had a series 60 and yes it leaked as much as my AMF Harley Davidson. If you did not see some drippings better check the oil there may not be any to leak out. :-)
Thanks love the video, I am a new subscriber.
I am a Freightliner Parts Salesman..common issues..(1) leaking oil pan gaskets. Make sure to change the bolts w/the grommets. There is now a kit just for the grommets! (2) Oil leaks at the injection tubes to injectors...don't just change the gaskets at the injectors...replace the six injection tubes (they come with the gasket). (3) Oil leaks at the injector wiring that goes through the valve cover gasket (oil can travel through the front & rear harness and cause electrical disruption between injectors and ECM), (4) DPF issues do to extended idle times, note cleaning the DPF filters does not bring your DPF filters to 100%!!! Install new filters and you want have replace them as often! (5) DO NOT DELETE THE DEF SYSTEM, THE TRUCK WILL NEVER RUN CORRECTLY AGAIN, AND IF YOU GET CAUGHT THE FINES WILL BE STEEP! NOT TO MENTION NO FREIGHTLINER DEALER WILL EVER WORK ON YOUR TRUCK AGAIN UNTIL THE SYSTEM IS COMPLETELY REPAIRED TO OEM SPECS!
The oil leak in harnesses seems to only be an issue on extended service intervals and or with shit quality oil as its not the oil but the carbon concentration in the oil ie how black it gets that it becomes electrically conductive
I know this is about dd15 but we have a big fleet of dd13’s (various years of freightliner cascadias ) and we have yet ,knock in wood, have a fuel system failure. More specifically a fuel pump. Hell we have a 2014 with just of 700,000k miles and we JUST put a one box into it which was surprising because we’ve typically seen trucks need one boxes wayyyyyyy before 650,000
How are the dd13s in general? I just got one def and egr deleted and I’m scared of either the dd13 messing up or the Eaton ultrashift 10 speed auto messing up (it’s a 2013)
In 2015 I had 4 2010 western stars with DD15s. 2 of them dropped the oil pump pickup at 300k, 1 locked up. I recently got them fixed. I put series 60 14L in them! DD15 are junk!
MORE FREIGHT SHAKERS ARE IN THE SHOP THAN ANY TRUCK
I HAD A 2021 ONE 50 MILES ON THE ODOMETER HAD PROBLEMS
I probably shouldn't say this...... But I work on Detroit diesels.... Oldest one I've worked on is the 6110s..
. I love all the two strokes....
. They just newer motors not so much...... I'm a class a trucker..
. John 48 state OTR...... More power to you brother..... Oh...... My father was a Novi....... My mother American........
I’m looking into buying a 2010 Columbia DD15 with 400,000 miles on it. Would you have any opinion on weather that is a good truck?
I was waiting for this video because that's what I'm running in our fleet from CR ENGLAND
Don't know how you work for them. I would RUN away asap. Fuck large carriers
U forgot to say that : that's u r main reason for black oil în such a short time , carbon build up on your piston etc ... is like shiting on your food , and eating it
Hello sir
I have 2015 freightliner cascadia dd15
I have sign spn 102 fmi 18
I am in trouble
I have change dpf one box
Change new turbo all sensors all hoses but code still hav do you anything of this kind
I already waste to much money
Intake system derate 25%
Did you fix your problem?
Hi would like next video about CAT C16
The EGR cooler at $3000 is cheep. I replaced mine in my Ford and it was $6000
YIKES
What you think?? Detroit dd15 455hp vs 505hp? West Virginia mountains pulling dry van or refer?
505
APU's are a safety item and a fuel saving aid. That's real APU's. Huge battery banks are bogus and extremely heavy.
My 2016 DD15 was squealing but only while driving and the sound of it goes up or down with the rpms - Took it to Freightliner - paid $300 for diagnosis - was told it was fan hub needing to be replaced - 2 days and $2900 dollars later for a 3.5 estimated job nothing was fixed ! The tech only test drove it in the parking lot - the squealing dosent show up until about 45 mph and I explained all this to them in the beginning
I went back made them pull my old hub fan from the garage and give it back to me - now I am waiting till morning to see what their story is
I am suspicious of a false diagnosis - its still squealing just as it did before I went to the dealership
Tech mentioned a saturated belt but said they didn't have one snd recommended I get it replaced
I am not paying $2900 over a sqeaky belt it thsts all it is. - I am going to take the old fan hub to a different shop snd see if they can yell me if its faulty or not
This has been a terrible experience so far - Anither guy was waiting 5 days and they still haven't figured out what the problem is on his truck
Maybe decriminalization of all drugs in Oregon was not the best thing since sliced bread idk but this is complete bull crap !
I am going to call my bank Monday and put a stop hold on the payment if Freightliner dosent come up with a solution worth $2900.00 very soon !!!
EGR valve, cooler, DPF will NEVER get better, you can BET ON IT! Also, you are mistaken regarding the amount of gases the EGR puts BACK into the engine... you said 10%, but it is more like 50%, 5X more!!!
I hate all this emission garbage. Killing engines for a feel good idea. Does all the def fluid, dpf and the rest of the emission bs not have an environmental impact? Or is this just like electric cars that they say are going to save the planet?
I think my 2011 dd15 is having a fuel quantity control valve. The engine seems to have a lope when it idles or like a surge. But no check engine light. Any thoughts? Truck only has approx 550k original miles.
That’s the quality control Valve .
I really wish I had this video back in 2016. I had a 2012 cascadia with a dd15. I made a left turn from a 2 lane to a 2 lane. oil dropped to 9 psi. (Scan gauge connected) No One could tell me. 2 months later I find out (with 3 Gal of Lucas in it) what's up. Do the tubes. 3 weeks later I am furious that I have oil in the water and water in the oil when at home . I had hit 73 psi on startup 3 days earlier. I thought I blew out the oil cooler. I cried. Filed Bankruptcy.End of ownership of a business. Don' ask.
Suggestion. When you do the tubes at a REPUTABLE SHOP( Steer clear of empire in Mobile)have the O-Rings of oil cooler done too. Same material to seal.
You need to do your research the series 60 wasn’t the engine that sloberd it was the old two stroke built before the 90s
We'll look into that
Good stuff!
i absolutely agree with you on the dd15. i have been truckin for 40 years the best most reliable engines are detroit diesel i have been runnin a 60 series for as long as i can remember never have i broke down and could not fix the problem easily love them like my wife can always count on them. Larry B
Lol!! I strongly disagree! Every time I've had a major breakdown, it's been a Detroit diesel. I switched to a cummins isx! And guess what?? I'm able to make money 💰 without usually spending tons of money on repairs! But to each his own
What's your thoughts on Amsoil?
I delete all the EGRs on my diesel cars, surely you can do the same with a truck and get better MPG?
Where’s the link lol can’t find it
I replaced the EGR valve on my car. It cost me $25.99.
you're pretty funny
Don’t forget about fuel pump blowing metal shavings all in engine
_But don’t forget you guys are operating in extreme freezing weather conditions, everything shrinks in those weather conditions, not to mention in those conditions your engines are going from extreme freezing to nearly 200° hot Engine and then rapidly back to freezing again, so what’s so coming up there may not be the same issue in the states with temperatures don’t reach below or minus degree weather nowhere near as often as in Canada_
If it gets below -25C I leave my running
Yep the so called cycles(every time your engine changes the temps so engine off to running engine) are as I heard somewhere on YT way more important than mileage. No wonder car engines wont last that long as truck engines, we put them thru way more cycels per mile than we do with big rigs. Add winter to it and it takes a huge shift of size in quick time from very cold engine that was off to running engine, like -20 C to + what, a 100 C? In like few minutes?
Puts more wear on the engine specially on older engines that use conventional oil because it gets thick and it takes way longer to start lubricating motor
the biggest thing all cascadia should replace is the freaking Magnet def faring cover. stupidest design ever.
Having trouble with cylinder head on mine. 125000 miles. 2023.
i drove 60 seriers in 90s,,,never a problem
Always change your oil every month with our fail.
a great pity, the best truck engine ever made for trucks was the 855 Cummins, they were oil tight
now the bestest is the V8 SCANIA
_Use MotorKote oil over all competitions in your diesel engine, it is the only oil in the industry that is 100% anti-friction, it’s $100 a gallon but trust me it is an investment that is worth it._
1100 dollars just for oil!?
@@ayliniemi
_Here is a demonstration of the motor oil that I use in my diesel engine_
th-cam.com/video/IrFl7ZlMklM/w-d-xo.html
Dd15, word to the wise replace serpentine belts and pulls every 2 years and water pump every 3. I do it as preventative maintenance, they are weak points.
My dd15 always get mobile delvac 15/40
You can get oil additives too seal oil seal and o rings might help sealing ,,,
I'll stick with my. .paccar.. mx13.....300k...miles
No problems at all.... ..💪👍👍👍👍
What year?
-40 is outrageous! Shut 'er down!!!
DD 13 ,15 , and 16’s classic example of German over engineering . Germans are capable of over engineering a toothpick ! When the diagnostic light is illuminated , you know your engine is running !
The oil leaks are caused by overfilled oil on oil changes 😂😂😂
I thought this guy had a fleet of trucks so how can he generalize about issues with this engine
It's the unfortunate issue with engine reviews on the internet. The valuable information is from the OEM'S themselves who have the real warranty data on hundreds of thousands of engines. The big fleets also can get some decent data once they have a few hundred trucks of each. The same goes with fuel economy... it's useless to use one person's value because there are too many variables at play.
I'm an engineer who fixes these warranty issues.
This why I am never getting rid of CAT C-15
EGR, the worst invention for any engine.
Who knew firing hot, unfiltered gases back into a engine block wasn't the greatest invention since sliced bread?
Absolutely, it's very easy, a diesel engine runs best on clean cool air.
It’s called the after treatment garbage on it
I'm back in the day if you didn't see oil leaking out of a tractor with a series 60 Detroit there was something wrong the sky was going to fall or you owe the IRS a billion dollars or something because it was not normal for a series 60s not to leak oil something was wrong with that day🤣🤣🤣🤣🤣
Did we the people ever ask this guy to shoot any video?
Did someone asked for this video ?
Coming from a small company that had nothing but pre-emissions cats I think the DD 15 is a joke. We have a fleet of over 30 Cascadia’s all with DD engines we’ve had five of our trucks blow the glued on piece of plastic on the driver side of the oil suction manifold completely off and lose oil pressure instantly. The O-rings are one thing causing low oil pressure but the manifold breaking kills them instantly. After seeing four of our own trucks and two outside customers trucks with completely demolished engines the owner of our fleet decided to pull every truck he had in and replaced the suction manifold some of which had already had the O-rings replaced due to low oil pressure. That’s a lot of money to spend because of crappy plastic parts. These new DD engines are not real Detroit’s this is a Mercedes engine I don’t care where it’s built but it’s a rebranded Mercedes engine. I believe in other countries they call it a Mercedes SM 471 which you can actually see the 471 just beneath the valve cover on a DD engine you can look this up. We’ve had a lot of bad air compressors which are a pain in the ass to change especially on the shorter nose trucks which if you’re an owner operator that’s extra labor you’re paying for to get it replaced. Get an older truck fix it up and be happy. We’ve not had any major problems with oil leaks other than the little seals around the injector lines which isn’t a big deal and leaks around the crank case filter or separator. Aside from that the engines do OK if one of the petty problems doesn’t kill it first. I consistently see owner operators with older trucks that they have practically rebuilt giving way better service than some of these newer ones with all the electrical and emissions nightmares not to mention the automatic transmissions when they go haywire. Honestly don’t see how owner operators afford to keep these things on the road. Debonded hoods the glue that holds the top of the truck together coming loose leaking windshields Frieghtliner actually put a plastic gutter type thing over the fuse box so when the cab leaks it doesn’t kill the sam cabin. I have learned to hate these trucks even though I know they’re nice and comfortable and do a good job when they’re working right but they are super poor quality everything is cheap. I had a owner of another trucking company explain to me why he would spend 50 grand on a high mileage Peterbilt or Kenworth and then take a gamble on how long it would run before he had to rebuild the engine or replace a transmission or drive axle and he said because if I keep good service records on these trucks and keep them looking good I can turn around and sell it and get back what I have in it and he’s exactly right and I’ve seen him do it for years. His early 2000s model peterbiults and Kenworth all with cat engines give better service than 80% of our newer cascadias. The interiors and cab definitely hold up way better
i went from owning 12 379" s with cats to all cascadias. fuel went from 4.5-5.5 to 7.5-9mpg. it would cost me 40-50k a year per truck in repairs. just traded in my 2019"s and got my new 2023"s. when you own your own trucks you will think different. you guys must all be horrible drivers or something to be destroying them. don't believe all the bs they tell you. put 80k on a 22 year old truck then 35k on a platinum caterpillar rebuilt then tell me how great it is ..
dd15 have big leak of power in my opinion
