    Can anyone tell me what the normal operating temperature is for the engine (coolant).

    I have a 1989 Chev 3500 4WD, with a 6.2 litre diesel with 228000 km. I have just bought the truck and it is the first diesel that I have owned so I'm not to sure about it.

    It is running around 200 to 210 it seems quite hot to me, but then again I really have no idea.

    Thought the gauge might be screwed so I went out, bought an after market and installed it, still running at 200 to 210. :dizzy::dizzy::dizzy:

    That's probably not too hot. But it is true with that many miles you probably need to investigate, by changing thermostat and check the radiator, and fan.
