2005 OVERFLOW COOLANT OVERFLOW

[joshkramsey]

My friend is out of town buying a very nice 2005 6.0 with lots of mods very nice truck. The truck is over flowing the coolant from the degas bottle.

Has the truck had a new oil cooler installed? Coolant filter?

Without a lot of investigating it is hard to pinpoint the cause. Could be anything from EGR cooler to Head gaskets. It would be safer to just not buy it... but if you are ok with the fact that you could drop 4g's on studs etc. then go for it.

Also could just be an over filled coolant system. But by no means am I sayin thats the problem. Ya'll need a monitoring system so you know the deltas.

Damn I have learned alot on this site!

If it were that simple that is such an easy fix... but you never know. Always look at something worst case IMO. No one here can really tell you what is wrong with it without doing some testing on the truck. All we can say is that it could be as simple as removing coolant to as bad as studding the truck... so free to 4-5g's. Checking the cooling system pressure would be a quick and easy test that would tell you a lot IMO.

Yea I told him everthing you have all said I agree. It does need a coolant pressure test for sure.

Any one from the Minnesota area with a good shop to send him to?

It would't hurt to get a reading on the ECT and EOT on a short drive.

What is high on the EOT and ECT for temps?

[F250SixOH]

At at steady 60-65mph freeway pace, the ECT must be over 190 (to get a correct reading) and the EOT should be within 15 degrees of that. If the EOT goes higher than that, it usually indicates a clogged oil cooler.
