My fan dosent work right. It overheat a bunch and when it does I shut it off and you can here the antifreeze bubbling and then when you here the bubbling stop and just turn the key back on the fan will kick on for exactly 30 sec then kick off and won't come back on till the antifreeze start to bubble again does anyone know why it does this I would just Hotwire the fan but I think it's something else but I would really like to fix it. It's hard to trail ride and not over heat. Please help. Someone who has a 450r said it was an eps sensor or something like that but I don't even know if a 660 has one of those.
