2012 Polaris Sportsman H.O

Hello Everyone, New here.. Got a quick question to those out there who know more, about these type of quads. I got a 2012 polaris sportsman h.o.. just reached my 1000km on my speedometer yesterday. Anyway’s.. I went out mudding, Tryed to cross a small creek. I got stuck in about a foot of mud, I shouldve went for it but thought nah, Eventually got stuck. I sat there for about a good half hour, Til my buddy showed up and pulled me out, Bike was all muddy.. Everything was fine, but I noticed that when I was in the water for awhile, My fan did not kick in, or start up.. I didn’t notice til after.. I left from there, to wash off all the mud and spray under, all over.. the quad. I went home parked, had supper.. went out, and went to see where I got stuck, I didn’t go in mud this time. But once I got home from a 8 minute ride, I was ready to leave again but I noticed My hot engine light was on? I parked it.. and One more thing, I got up around 4 this morning it was cold out, and went out to my quad, I turned the key, and still.. hot engine light, I touched my engine and it was cold? :ponder:
