    Hopefully someone can help.. I recently purchased a case 721c loader. We have pushed with it a few times and it runs great but the engine doesn't warm up. It had been cold, 0-10 below but even running it for 8 hours the temperature gauge barley comes up and the heater blows luke warm air.. I was thinking a new thermostat but figured someone here might have other thoughts.
    Thankyou
    Robert.

    Sounds like a failed thermostat. Likely stuck open so it can't build any heat.

    You might have to block off part of the radiator as well. I have an old Michigan loader that I have to block off a little over half the radiator or Ihave the same problem.

    It is full of coolant.. I blocked about 1/3 of the radiator and it helped, but not much.

    Likely thermostat then.

    Or it's completely screwed up, best to get rid of it. I'll come down and take it off your hands, wont even charge you for hauling it away, lol.
