Last year went for a ride and mne started to overheat with the fan running, looked in grill and rad was clean. Another fellow came along to help me out but on close inspection with a flashlight we found the backside caked with mud. Couldnt see it with the fan in the way. After a thorough cleaning all was good. Just rhought you might have the same issue.

My bet is the rad being caked up. But having said that, you can test the sensor by disconnecting it. The fan "SHOULD" come on when you disconnect the sensor. Although I have seen the sensor bad and the fan still not come on. Also, if there's air trapped in the system, it'll run hot. Bleed it, and see what happens.

just found this thread thru a search...i am "in the house now" but if i disconnect the sensor (on a 2001 500HO) , assuming the system is the same, If i disconnect the sensor, it says the fan should come on. should the fan NOT come on, would that mean what? fan is bad, i would guess it does now mean the sensor is bad? My 2001 500HO is currently in an overheat situation and not sure hot to test if it is the fan, sensor or other issue.
i pulled the fan and under 12v power it does spin. sounds rough but it does run....and its gonna get replaced regardless. but if its not getting turned on...then , well...thoughts?

2002 Polaris 500 H.O. overheating
If you unplug the sensor the fan should NOT come on....you have opened the circuit. I found a replacement sensor via a Google search at a resonable cost and it was at my local auto parts store. It was a NIssan sensor. It works great. Same ON-OFF heat range as Polaris and mounts the same. Hope this helps you.
