Oil cooler?

[417brobinson]

I have a 06 F250 with 158,000 miles on it. It's running 12-20 degrees difference in eot and ect. I'm going to do a flush on it by the weekend and see if that helps. But another question is if the oil cooler is partially clogged can that create pressure in your degas bottle? EGR delete was done about 6 months ago should have done the oil cooler then.

Sorry, I thought I was in General Discussion.

Any input would be appreciated.

ok so fist off pressure in your degas bottle without the presence of the egr cooler most likely means one of two things... Head gaskets or bad Degas bottle cap...

I would start with the cheaper one


also...I would do a FULL coolant frlush with restore & Restore+ and drive it a couple days to flly clean out your system... THEN go back into it and change out your oil cooler with a new one...

FYI: once you flush your oil cooler you will need to swap it with a new one as flushing does not clean the oil cooler...just cleans the system for the future oil cooler

So are you having excessive pressure in the cooling system? Puking out the bottle?

I replaced the degas cap. I'm still having quite a bit of pressure when I shut the truck off and slowly loosen the cap. Probably blown head gasket.

Well there is going to be pressure there, but it shouldnt puke out the bottle. If it is then its either over-filled or over-pressurizing due to head issues...

I figure if oil cooler is bad it might be a good time to do all of it. That is as long as flushing wont clear the oil cooler.

"quite a bit of pressure..."? I'd measure it first before assuming the HG are blown.
If you do the coolant flush be prepared to replace the oil cooler even sooner.

There is always pressure in the cooling system. Its a closed system so when the fluid gets hot it creates pressure. If you are puking any coolant out of the cap while you are driving, then you have a problem.

Anything that has a cooling system will have pressure, hint all the warning to not open while hot. My cousin opened his 240sx radiator cap as soon as he pulled in my driveway and was greeted by a shower of 190* coolant.
