I could use some advice and input. I have a 2004 Polaris Switchback that overheats if it is not running in several inches of loose snow or powder. It has done this on and off since I bought it new. This weekend I went out to my cabin and it kept over heating on me. I have read that this is an issue on some Polaris'. Anyone else run a Switchback and have this issue? Any idea why it keeps getting hot? And any ideas on how to fix the problem?
