Came here to test my water pump
Find out i had blown HG
Thx
This guy is a top notch mechanic and I ALWAYS learn something from his videos. Never knew you could test flow like this.
Is there anyway you could do a video and tag me in maybe about how you did that head gasket test
Great job. You’re a true mechanic not a parts changer. Thanks
"Adept" sir that you certainly are. Brilliant video yet again, thanks for sharing your knowledge.
Great vid! Personally I would've preferred a faulty water pump to a blown head gasket!
Great video. Straight and to the point. You rock.
man you break things down so easy to understand. thanks
Great informational video, Josh.
More knowledge, good job Mr. Adept !
Love the combination video diag plus distribution of the week.
Thank you adding this to my tool belt
Always interesting stuff thank you
That's a handy test if you've got all the tools to pull a vacuum or pressure test the flow of the pump. Never seen anyone do that in a shop or use those tools. So my final thought is that you're a wizard 😂.
Just when you don’t think you can learn anything new...thanks adept ape. I will be using this.
cool stuff...learn alot from ur ideas and techniques
Another great video from my favorite diesel TH-cam channel
Another awesome video, simple too the point .
Great information
I was thinking you could have run a hose back into the radiator from that same location and do a flow test for the folks who might not have a 500 dollar low pressure CAT gauge handy.
Loved the explosion once you discovered the blown head gasket. I totally wasn't ready for it.
@@TheCRTman Yup! I nearly lost it on the explosion.🤣😃
Nice complete video
Good Work was done
Thank you so much for your videos. I’m learning a lot. I have the same issue on my C15 it’s overheating. So how I’m going to take the vacuum out? Please let me know. Thank you.
excellent helpful video thank you
Good video!!!
Thank you good info
Very helpful
Well good news Sr. you just saved 1000.00 for a water pump " Yeah " But you need 10000.00 for a head gasket 😜😜👍👍
You did not mention the fibre impeller that detatches itself from the steel hub on some earlier 3406 water pumps, I have replaced that impeller in several instances across Europe. No coolant loss but engine overheating. Regards from uk.
Damn good video! I hate to admit this but I guess I am dumb because I have never pulled a vacuum on the coolant system to open it and change anything. Hell I never seen it done. Awesome
I guess u never worked on stuff that holds 10gal to 100gal of fluid! We do it to change simple hyd lines so u dont loose $$$$ in waste. Work smarter not harder I tell the guys who dont know better.. now you've learned something today
@@kwmiked well they say if you're not learning something than you know every damn thing. I been working on trucks and heavy equipment for a good while, however long it's nice to learn new tricks.
A shop vac..... not just for carpets
Oh
Oh l
Just to ask ,I have come across half a dozen or so cracked impellers on cats an at at least that many on two stroke Detroit wits brass impellers .The first one really stumped me for a quick minute, they will flow almost normal when cold ,but once they start warming up they spin and the temp goes up like a rocket.
Hi there Josh I do the same same thing and I changed water filters it works pretty good still got be quick question why were some of the early 3126 painted gold thanks Scott
Like allways thanks for the good information. Is 15psi the standard for the bigger cat engines? What would it be for a c7?
Wow! You know good!
Do they have a gauge that can be mounted on the dash of your truck with the other gauges that will all ways show you the pressure?
What was the pressure reading after the head gasket was replaced? This pressure must read different at the radiator or coolant bottle correct?
Could you do a video on airing out diesel fuel system? Like when you change a injector
Hello, I have a C12 that is getting some coolant in the crank case. I have watched many of your videos which by the way are great. On one of your other videos you say that the pump weep hole on my motor goes into the crankcase. I am not overheating and in fact my operating temperature is very stable and where it usually is. Could the water pump be the culprit here and can I test it like you did on the C 15? The motor also started to get a lot of blow by but I.m not sure if this related to the coolant in the crank case or possibly another problem. Motor seems to be running well,however I use 3 gallons of oil between changes at 12000 mile intervals. Any help would be greatly appreciated.
Ive gota ask are C15 engines known to go through head gaskets? Have a buddy with one in his truck and he blew one at 300k miles, just seems soon for a motor like this. Hes just a farmer too nothing insanely heavy just grain.
Thank you
Do manufacturers offer a permanent mount coolant pressure gauge? Would seem a useful monitor for extended use engines, like Marine or hauling use, or even construction and farming, gennies, pumps, etc
Marine installations have a pressure gauge
Thanks
Do you have the part numbers on adapter you used to go into the port
always look forward to the destruction of the week, and this one was great as well. That was great
Is the gauge low because it wasn’t vented? If there is air in the line it will read low
Do u have a video on 3406e ac/heater shutoff valves. Dont want to turn on the wrong valves
Would a master injection test kit work for checking this the gauge and fittings?
What was the test with the bottle? Did you hook up a bottle with water onto the high pressure discharge of the surge tank to determine it was over pressuring instead of using a cooling system pressure tester?
Bro, you mainly use the pressure tester to find an external leak in the system. Using the water filled bottle from the overflow/ vent tube from the tank just shows pressure entering the cooling system internally.
Gday mate
How much and how often the water pump (part# 10R8660) on C15 SDP 16182 twin turbo leaks from weeping Hole to indicate needs replaced and if so can you replace the seals and gaskets on it instead of replacing the whole unit ?
Where can I get these testing gauges
I got 3406B old cat and its water pump dipping coolant should I need-to change the pump ? Thanks
How did you pull the vacuum ?.
Do you have any videos on how to replace water pump on C13?
My dad had to replace a bad shut off valve on a 250 gallon fuel tank for a mobile home, he put a shop vac on the opening of the tank for the same reason. Didn't lose a drop of fuel
Hi we have a c16 cat we did a full inframe over haul never had this problem before after when the driver was sleeping the engine started running rough and dripping cooling from the reservoir then the next day that it was turn on white smoke came out from the exhaust and it had coolent on the piston 1
How to get rid of temperature problem on my 3406e cat engine please and It only uses one thermostat
You could save a heap of time and inconvenience by simply attaching a gauge to the pressure cap..... raise the pressure to 1.5 bar blip the throttle and you will notice a small reduction and then a stabilisation....if your gauge stays down you will shave a restriction (radiator etc)....if you don't have any pull down or reduction in pressure.....the the impeller may be corroded .
Always remember to pressure test the system cold and the cap also before proceeding deeper first .
ALL IS LIGHT 1÷144
What causes water to be pushed out of your overflow tube on ac15 acert
Gday Josh
Is this the same procedure for a c15 acert?
Cheers
Looked through your videos and did not see a video on changing the water pump if it was bad. Did I miss it? If not, might be a great one to have.
Saves him the expense of a water pump but winds up being a head gasket! 😂
Better than him needing to replace both, with one of them being unneeded.
What would the temperature go up to? When It overheats. I have a 2ws that can clutch will not engage automatically. Fully loaded going up Coachella hill outside temp 115 my truck usually goes up to 227 no alarms.
Just replaced the water pump and thermostats. Still running really hot while pulling a steep grade.
👍👍👍
I have a C15 engine overheating problem. Mechanic says head gasket torn or crack in head. Problem is there is no evidence of water in crankcase, dipstick, and no water vapor coming out of exhaust. Also no water loss coming from air compressor to air tanks. And no traces of water inside cylinder head or head cover. You think perhaps my water pump is not circulating water?
Wait, so what exactly is wrong with the fire ring on the gasket?
Great video! Where could I purchase the tool to draw a vacuum on the cooling system?
Thanks
Caterpillar sells transducers, which we use to put a vacuum on fluid systems. Part # 5P- 0306. There the cats ass if you ask me.
Search airlift coolant system leak checker on amazon, works good to get all air out when refilling a system as well
If pressure was getting in the coolant shouldn't the pressure test of been higher than 15?
ADEPT APT
Is there any other water pump testing you can do to test and check if the water pump is pumping water into the cars engine and into the cars radiator correctly?
How do you test the water pumps Pressure, how much Pressure the water pump hoses are at?
The Purpose of the Water Pump is to circulate the radiators coolant into the engine and radiator?
Really great diagnostic skills. But for some reason it always bugs me when people say “dee-sil”. I know it’s weird. But the original pronunciation is “dee-zul”.
Where's your shop at?
Take off the head and the head gasket is good not burn and re check the block from the cutting the block we change the head and had it on idle for 20 hr and everything good drove 150 miles and the coolant start to coming out of the exhaust again if you have time and have a thought about that and could help us and reach out i would greatly appreciate
Testing here could possibly give higher reading than testing where cat says to test in the plug, number 2 on cats illustrated. Correct? Because where cat says to check is much farther away from the outlet of the pump. I assume that is why cat whats you to check it at the thermostat housing. But it should be very minimal difference right?
I just checked the 3406e vs c15 test procedure and the 3406 says a specific plug in the t-stat housing. The c-15 just says remove a plug in the housing. The older 3406 also does not specific a specific rpm. It just says atleast 15 psi. So i should be safe to assume 1400 rpm the 3406e should also be atleast 15psi. Right? I only have 12. So pretty sure that is why the truck is overheating.
Have you had a problem with a c13 accert that coolant it's in the turbo side
And no emissions in radiator
Hello, thank you for excepting me on your platform. I have a 3406e cat . it's been sitting for 8yrs now. I noticed something I have coolant in my oil. I've changed oil a few time the same thing. I pressurized the system and noticed leaks coming from piston #2. Then someone told me it's my oil Cooler. Help PLZ.
Someone correct me if I'm wrong...
Oil cooler will put oil in your coolant.
If I had to guess, I'd say a liner o-ring.
The only way I've ever saw a water pump fail is a bearing or seal failure
Is this the same psi for a c15 acert my is getting hot only when in a pull
The water pump is the same, should run the same pressure.
@@AdeptApe okay thanks I will check it out
How do you know you are measuring pump pressure and not just hot water pressure?
Flow
When you run out of Cat's to work on... gonna join the blue Man crew? JK hope the baby and wife and the other "kid's" are all well and good
Mine is doing the same shit hope it's the gasket not my head but I already have 1.3 mill miles so I doubt it so for now I'd poured a bottle of sealant in it and it works never thought it would but it's just for now ...nice video
Just added a bottle of extended other troubles down the rd lol
Might just be head gasket man, sounds like shes made you enough money to get some back!
Good looking out unfortunately for that poor guy it was worse than the pump. Yep. That's about how it goes sometimes.
after looking at a million headgaskets , that one doesnt look like it was leaking
I love the way they moved the weep hole location and put a piece of foam in the hole.Bit me in the ass once or twice.
I got oil coming out weep hole
That destroyed head gasket didn't have much of a chance to begin with, those cylinder walls are TINY between each piston, wouldn't surprise me if a crack was soon to form afterwards!
Midnight Mechanic Cracks aren't generally an issue ,only in gasoline engines with thin castings (generally Ford's) acidic antifreeze causes pinholes which are by far more common in unmaintained diesel engines.
Plenty of Diesel engines can form cracks from sheer vibration and cylinder pressures, those cylinder walls are way too thin for my comfort for them to hold up under load, especially since the head gaskets are proof they couldn't hold up to the heat and pressure.
+Midnight Mechanic you can't really tell how thin those cylinders are just from looking at them from the top of the engine without pulling the sleeves out. big diesel engines such as this one doesn't have cylinders like a gas engine that are actually part of the engine block, these are cylinder sleeves that you can pull out and replace. in all my year's of doing diesel engines i've never really seen one that wore so thin that it would crack, you would have a lot more problems long before that would happen and yes I've seen a lot of cracked cylinder sleeves but not really from being worn thin. before that would happen your engine would have so much blowby it would make you choke on all of the smoke and that would be if you could even get it started due to the lack of compression to get the fuel to combust.
La mera pipa
Darn if it were only the water pump...
seems like a lot of work, most stuff nowadays have a temp gauge you can look at to determine the same thing.
Temp gauge doesn't tell if there is flow. You'll go hot from a radiator core with bug clogged fins, a stuck thermostat, blown head gasket, cracked exhaust runner, and lots of other Gremlins. None of those are the water pump. A bad pump will show low head pressure until you boil coolant in the jackets. A cracked liner will show pressure spiking high rapidly. Bug filled fins will show normal head pressure rise until the thermostat allows the entire system to overheat, then "boiler Spike", or sudden dropping as the cap releases because of the head pressure with the stat wide open. His vacuum coolant retention actually hid some of the pressure Spike from the blown gasket, but the fairly rapid temp rise remained.
Sorry my question has nothing to do with water pumps. I had 1 million one hundred thousand miles on my ECM. ECM went out I put another ECM from a another Cat motor on their it lasted 4 days it burnt out. Now I'm putting another ECM from another Cat motor on there with a new wiring harness I hope this fixes the problem., the used one of them fixing to put on there has been turned up to a 550 it's been checked by the ET and hopefully it lasts more than 4 days for $850. If this one burns out what the hell could be the problem.
Useless test in my opinion
