Also think of this ....If your fan has some mud dried in it (usually at the rear)the fan will run more often to keep the quad cool. This will still cool down the rad without the hot light comming on ...But will cut down on the life of the fan!!!!...So the cleaner the rads the better.....Check them out!!!!I have 1000 miles on my 2006 S.P 450 and no HOT light for me yet!!! My wife's came on once so far since we ..............I didn't replace anything on these quads yet!!!!Proper service being done though.....Caper....
I very happy with Polaris so far!!!!!! Just thought I would throw that comment in.......

 

You might want to call POLARIS directly. My buddy just had a problem with his fan kicking on with the key not even in once the battery was hooked up. Come to find out there was a recall on his and they fixed it for free!

 

What year and model Polaris did your buddy have the problem with???...Thanks...Caper.......

 

2005 sportsman 700 twin. i posted a recall section on the main polaris page. its a $200 part,but your local dealer will fix it for free!

 

My fan/sensor have failed...
