2004 f250 6.0 diesel engine oil cooler

It is generally not recommended to bypass the oil cooler on a vehicle, as the oil cooler serves an important function in the operation of the engine. The oil cooler helps to regulate the temperature of the oil, which can have a significant impact on the overall performance and longevity of the engine. If the oil becomes too hot, it can break down and cause engine damage.

If you are experiencing problems with the oil cooler on your 1996 Ford F250, it may be best to have it repaired or replaced rather than attempting to bypass it. If you are having difficulty with the oil cooler, it is important to diagnose the issue and address it as soon as possible to avoid potentially costly damage to your engine

you may have to prime your diesel before it will draw fuel

Is this a diesel engine....and are you talking about the egr cooler?

You didn't bleed the oil properly. The injectors are oil pressure operated.

Teflon tape works great for this and is what is usually used on Fords during installation at the factory.

WELL SHOULDNT TAKE OVER 2 HRS.YOU REMOVE OIL FILTER AND FRONT AND REAR OIL COOLER HEADERS AND DISCONNECT BLOCK HEATER ELECTRICAL CONNECTOR.THEN REMOVE REPLACE HEADERS O - RINGS.

My 2004 was doing the same thing and it was the egr cooler, i bypassed the cooler and replaced the oil cooler while i had the top of the engine apart,problem solved

There is a possibility it is overfull. Ford put out a TSB which lowered the hot full level on the recovery tank about an inch. These recovery tanks also have had a history of developing pinholes and cracks on the top side that sometimes appear to be leaks from the cap. If you do not find a remedy with the tank itself, there are tools that can be used to check for combustion gasses in the cooling system. If you find combustion gasses in the cooling system, have the EGR cooler pressure tested before pulling the heads. If you do have to pull the heads replace the headbolts with ARP studs and nuts.

Check the o-rings in the female side.

my 97 f350 powerstroke dide the same thing it ended up being the trany if screwed. It needs to be rebuild chances are the planitarys are bad and dumped iron into the valve body
