My buddy has a 2002 Sportsman 400 that had been overheating. I took a look at it and found a stick in the fan from the back side. We removed the stick but the fan will not kick on. Does anyone think that the moror went bad from constantly trying to turn or could the fuse have blown (is there a fuse?)

 

my fan got all froze up w/ mud and the wife did not notice utill the hot!!!!! was flashing and it was spewing coolant all over ..i reached down and un-stuck it(spun it by hand) it it worked but was very noisey .........cleaned quad and took to dealer POINTED OUT THE NOISE OR THEY NEVER WOULD HAVE FOUND IT.... i was surprised to have it returned to me w/ a new fan,,i thought i was going to eat the repair ... ;; note-- get a fan override switch for mudding and deep water fun

 

unhook and it and feed it direct power off the battery to check to see if its the fan or not.

 

take a screwdriver and make it connect the two wires on the thermostat switch on the radiator.if the switch is bad the fan will kick on if not you have a broke fan or wire.

 

If it's the thromstat. Take it out and apply a little heat to it with a propane torch. If it's stuck ,it will sometimes unstick it by applying heat . Not too much heat ,just enough to unstick it

 

bet its the fan .i have heard of this alot

 

I had the same problem and it was the sensor on the bottom right of the rad ($70 at the dealer + 1 hr labor). Mine would overheat and the fan would not come on...I hope this helps...

 

i bought one off of ebay new for $15 and changed it my self.

 

So did this fix your fan? 15 bucks is a great deal

 

yes it did.but first jump the two wires together that go to this switch to make sure the switch is the problem.once you put straight power to the fan it should come right on.if not its either your fan or a wire broke.
