Have a 98 Polaris sportsman 500. We took it out and It over heated in us. Sprayed the radiator out and it cooled back off. Well it sat for awhile while I was waiting on brakes and stuff like that. Got it all running and we was riding it for a bout 15 minutes and it got so hot it boiled over. Also when I turned the key on the fan came on. I was looking around and found a wire clipped. Pieced it back together and now my fan won’t come in at all. And it gets hot really quick in my opinion. Any suggestions?
