As title says, my 06 rhino started overheating last week during moose hunting once and a while. I belieive fan not kicking in. Temp lite on, turn off engine, turn key on , no fan. Just ran heater to cool down. What do you guys think most likely culprit, fan temp switch? Not smoking or loosing coolant. Doesn't do it all the time. Thanx for your input in advance. ps installed Jame's sheave and weights, orange spring. Great low gear, much quieter cruzing, gained about 5km/hr. I love to spend money on **** that really works! jeff v sk. canada

if the fan is not switching on it could be the fan or the thermo switch.

jump the fan and see if it runs first.

Did that. Fan works. jeffv

gotta be the thermo swith on the rad then.

Thanx for verifing my suspicions. jeffv

Check to see if you are getting power to the thermoswitch with a voltmeter. There is a circuit breaker wrapped up in the wiring harness, in the battery box, that is notorious for failing.

thanx, I'll check that as well! jeffv

Is the rad hot when the temp light comes on? If there's air in the system, the water pump may not be circulating coolant to the rad.
