I have a 15 sportsman 570 I love the bike but lately it's been having issues overheating. It only overheats if you stop moving and let it Idle for a few minutes so I'm pretty sure it has something to do with the fan. The problem is this only happens sometimes it happened about 2 months ago and I tore the atv apart took out the fan and ran it of 12volts and it ran fine. I checked all the fuses and they were good. I checked the relay by replacing the original and seeing if it had the same symptoms, which it did. Eventually the fan just started running normally and I thought I had fixed it by moving a bad connection or by making the fan run on a battery. However 2 months later it's doing it again (or it did it today with any luck it won't do it tomorrow) any idea why it's doing this or more importantly why it does it intermittently? Thanks.
