05 6.0 Help

[Sarge261]

Hey All,

I am working on a 2500 HD 6.0 and here are the symptoms. The truck overheats at idle. Its not consistant though. The customer wanted me to change the t-stat, so I did and I flushed the coolant and replaced it with some fresh dex cool.

The coolant temp was about 40* off so that was replaced also. It took forever to get all the air out of the system. I was looking for a bleeder valve but couldnt find one.

I know there is a TSB out there for trucks with plows having an overheat condition with the plow on and driving slow. Is there anyway to check the fan clutch? This happened to the customer so I am not sure how long he drove it hot. When the cap was off the resivoir the coolant was jumping out of the bottle so I am not sure if there is a HG issue here either. I dont smell coolant in the exhaust, it has good heat, so I know the tstat is working.

Oh yeah its a 4x4 with a plow, the plow was on it when it overheated on the owner, the plow is not on it now, and it still over heats on me after the repairs.

Thanks for the help.
