7.3 Powerstroke oil cooler reseal/replace

[@packingbone1953]

Lee is pretty lucky to be working in the shop with his dad all the time, a lot of good knowledge being passed down right there.

My 2000 f350 7.3 has black oil in the radiator. I changed the oil and change the antifreeze and let it run. Next day I see black thick oil again in my radiator Reservoir. Please tell me what to do? 🙏

Flush the system with cascade dish detergent then immediately drain it reseal/replace the oil cooler then flush it again with the cascade until it’s a clean system.

[@samuelhand8366]

I’ve seen a lot of people talk about flushing the oil and coolant out when you do this job. I’m gonna do mine soon but I noticed you just drained each and didn’t flush them. Is it necessary or just a drain will do?

[@AutomedicGarage]

There was no contamination to the coolant system so no need here. I flush when the coolant has oil in it. I use cascade dish detergent to clean the coolant system out.

[@rm4786]

This is the most informative video ever. I have. 2002 ford excursion lifted and it makes this job so much easier.. I followed this step by step and I tell you it looks very easy to do.. 1st time owner of a 7.3 diesel . This thing has 350 k miles on it and it’s the best unicorn engine I ever owned

It’s not bad, get dirty and fix it.

[@geraldvillarreal1630]

I removed the block heater to drain it, it’s messy but not as bad.

[@AutomedicGarage]

That’s what I do

[@alsaku33]

In my experience...take the whole unit out as one and put it back as one. Use the small drain plug on the block next to the back side of the cooler to lower coolant level enough for removal. If you don't have a press just use a large ratchet strap and you can get both ends "pressed" onto the cooler while it's sitting on your work bench. Make sure you clean up the bores on the two "end caps" that get installed on the cooler tube!!! Use some Permatex High Tack on both gasket surfaces (cooler and engine) so your gaskets remain in place while you go to install. I put the gaskets on the cooler and just slowly positioned the unit into place. There is no need to pull your front wheel or fender liner. Super dirty shitty job laying on your back for sure. Clean everything super well while you are in there so you can pinpoint leaks in the future!

[@AutomedicGarage]

@@alsaku33 since you just picked my video apart sounds like you should go make your own video. Done over a hundred with my method. I have a lift, I like working standing up, and having a clear line of site to do the job right that’s why I remove the wheel and liner.

[@brandonwestbroek7787]

Have you ever seen the gasket between the cooler housing and front cover go bad? I got a small leak right there and that’s what I think it is. Also don’t want to change my cooler on my own, this video gives me some confidence.

Not a hard job just messy. Yes, they can leak there but most commonly leak at the orings front or rear.

[@markhouston7.334]

If I replaced my injector cups but still getting fuel in my coolant ‘ should I change my oil cooler O-rings?

[@AutomedicGarage]

Is it fuel or oil in your coolant? If it’s fuel in def not your oil cooler, only oil and coolant have the possibility of mixing there. Fuel can only get in from a cracked cup. Are you sure it isn’t residual from before the fix? Whenever I have contamination of oil or fuel in a coolant system I flush with garden hose water then flush with cascade dish detergent, not dis soap but liquid dishwasher detergent. I’ll premix the detergent in some jugs of hot water and shake it up then pour it in and go drive the truck. Then drain and flush with water again.

[@Dallmke]

[@frankvacanti5277]

I have done two of these. About to do a third. I remove the 1/4" block drain by the oil filter no mess(shower). Than unbolt the three bolts on the rear housing and pry the cooler and rear housing from the front. I have left the front housing bolted on the last two of these that ive done just clean inside of it and press the cleaned reringed cooler back into the front housing. They have not leaked. One was done 2 years and the other almost 5. Saves a lot of work not removing that front housing. I watched the diesel tech Ron video years ago before doing the first one. R.I.P. Ron

[@AutomedicGarage]

I always remove the front cause a lot are often oozing oil around the gasket plus if I say I’m resealing someone’s oil cooler I do it 100% and do it all. I also do not remove the plug for the coolant because once you have one strip out because of A) being over tightened by the previous mechanic or B) oxidation from the to metals causing it to strip because then you have to explain why you had to buy a new oil filter housing to the customer. I reinstall the front first and press the oil cooler into it also.

[@frankvacanti5277]

Drain plug on the block not the filter housing. Not cutt'n on your vids man. Now that these trucks are over 20 should do both. I only work on my trucks and van(u joint off road ambulance 4×4) i'll be steam cleaning the engine before i do this new cooler replacement.390 k

@@frankvacanti5277 good deal. Thanks for watching

[@queenofspadz]

Can the cooler be installed with both ends on the tube, or does it have to go in piece by piece like you've done here? Really appreciate the warnings about that aluminum front cover. This will be my first time. 02 F250 7.3L w 400k miles. No idea if its ever been done on this truck, bought it at 325k miles.

[@AutomedicGarage]

I prefer the method I showed otherwise your trying to stick it in a press or whatnot to get the ends on which can also result in cracking one of them. I can almost guarantee yours has been done at least once.

Can the oil from the front position of the oil cooler drip down to where it makes it seem like there’s front main seal leak? Just bought a 03 7.3 and I’m trying to narrow down some oil leak it’s got.

[@AutomedicGarage]

It can cause the fan will blow the oil back into the front of the motor. Degrease everything get it warmed up and look for the drip.

[@kieran8720]

Could easily be something in the valley leaking down. I have had that in majority of the 7.3s I have owned. The rear and front main seals almost never go bad in these. Did you end up narrowing it down?

@@AutomedicGarage yeah !!!!! Thank you I’m assuming it’s oil tbh because I’ve had an oil leak , my coolant literally disappears when I drive as well. I can do the injectors or heads glow plugs when I have the time or the oil cooler.

theoretically , can you just remove it from the oil filter side and reach in to the front to remove the o rings and change it that way, mine is not leaking from the gasket up front

because the gasket in between the housing and the front cover is absolutely dry and why take a chance in breaking the ears off the front cover if its not leaking the oil is leaking when its cold from the front o ring when its cold only , Im sure its just a bad o ring, my engine has a half million miles, so I just dont see opening up a can of worms if I dont have to
