My K20 would always overheat when runnin' the snot out of it in the mud. I just put a new thermal fan clutch on it (it has a factory style 5 blade fan) and a fan shroud with the bottom trimmed because of a 3" body lift. My temp gauge is new also. After about 1/2 hour of running 3000 to 4000 rpm in the mud the highest the temp made it to was 220 degrees. Is this ok or should it be lower? (stock 350, 3 core radiator, about 50 degrees outside) I plan to take out the a/c coil in front of the radiator, would this help at all?
