    How to test thermostat

    Coolant keeps coming out of the over flow so i thought it might have been the head gasket. After changing it i went back out and the same thing happened. Could this be happening because of the thermostat not working properly? How can i test to make sure that it is?
    Thanks

    If its overfilling/puking out you might be overheating; stat stuck closed. If it was stuck open the level would be low.

    It is overheating i get the p1116 code and coolant is coming out of the overflow. Do you know how to check if the thermostat is stuck?

    i know to test automotive stats u place them in pot of water and start to boil it. It should open before the water boils. Not sure how you can test the one on the ski, with being in a case.

    went back and tested it at 195 degrees and the thermostat opened... Any idea of what else can be causing the coolant to come out of the overflow?
