    Hello I drive a Kenworth T800 with a Cummins isx and the coolant temp is very high. What are ideal temperatures. Is 180-190 degrees good?

    Diesels actually like heat. 200-215 is about right for most engines.

    What do you mean by very high. What you quoted or significantly higher?

    Depends on the truck. My mx-13 runs at 160-180 unloaded and as high as 210 loaded depending on what im pulling and where as well as temps outside.

    That's good right there. That's normal traveling on flat land. It'll creep up to 200 plus on hills. The fan will come on at 220. If the fan don't come on at that point, you're gonna be stuck because your truck will cut off possibly. Your fan clutch may be busted at that point

    180-190 is fine if we are talking a typical tractor not meant for specialized use. If you get over 220 and the fan doesn't bring it down, you are fixing to have some problems.

    It also depends on the location of the temperature sensor. The heads are going to be a lot hotter than the oil temperature at the bottom of the block. Or the temperature of the coolant at the water pump.
