I am looking at a truck thats building coolant pressure in the reservoir. Its a 04 f350 with about 104k on the clock.

Could this be an EGR problem or definitely head gaskets?

Thanks for any help!

its actually a buddies truck that i am probably going to buy.

I didnt want to here that but i guess its not terrible bc if i was doing the head gaskets, i would do an egr delete as well as an oil cooler.

is it easy to just pull the valve or do you have to do the whole procedure?

I will try to get back to you with the temps. truck is currently sitting

well its ofcourse easier to pull valve, but its good to know if oil cooler is bad or not...

and how much pressure are you seeing? is the coolant level good and not over filled? is engine over heating at all? water pump pumping?

well first step is remove the egr valve and look down.. if there is puddles and wetness, its most likely EGR cooler...

Is it an early or late 04? Early 04 has ICP under the turbo and a round body EGR cooler. Late 04 has ICP in the right valve cover and rectangle body EGR cooler. Early EGR coolers less likely to leak.
