Gravel truck owners or operators?

Never a problem with over heating and the fan is never on. There is about 10 different tunes for this engine, could have something to do with it. Have you checked your rad, my dads duramax was stuffed full of debris, he had to put a new one in. Im running 180-190F water temp.

Will get back on it next summer. It's running a 350hp tune. I sprayed cleaner through the rad and pressure washed out but I think I'll have to completely pull it out and clean.

My pops tried to clean his, there was no way it was jammed full of crap, he had to buy a new one and install it.
