I have a 95 Polaris xplorer 400 and it has recently been over heating at first I thought it could be a thermo sensor problem so I rewired my fan and put a toggle switch on it so I could turn it on manually but then I heard what sounded like water boiling and I have tried removing the thermostat but I'm not sure where it is located I found where both hoses run into the motor one on the head and one kinda behind the pull start but not sure how which is the thermostat housing

The Polaris water-cooled 2-stroke (350/400) did not have a thermostat. Verify your fan is operating properly & no obstruction thru the radiator. The thermal switch in the top center of the radiator just below the cap is the usual suspect. Unplug it & jump the wires to see if the fan runs. The thermal switch turns the fan on at 190 degrees, off at 175. Check with a thermometer. If your still getting a hot light after jumping the switch, then start to suspect your head gasket.
