Hey guys. I have a 2013 rzr 800 with about 1000km on it. Went for a ride yesterday, first time since last September. My temperature ran up to 105 deg and the engine light came on like it was over heating. Fan kicked on but wouldn’t drop the temperature. There is a rad relocate on the machine. Rad is very clean. Once I stopped moving the temperature drops real fast down to 20-50 deg. Then as I sat and idled I noticed the temp was going all over the place 20-90. Felt the hoses and rad itself and all felt fine, nothing too hot. There is lots of anti freeze in the system. I do not believe I have air in the system. I am thinking maybe stuck thermostat or possible temperature sensor. Any suggestions on where to look?
