godeep Posted December 3, 2004 I own a 2001 Ktm 640 supermotard. My temp light stays on all the time. The thermastat is working the fan comes on and off. waterpump looks to be opperating fine. Only thing i can think off is the sensor that plugs into the rad which also turns on the fan. No hoses are kinked or leaking, the dash lite is only for the cooling system. Any ideas or help would be great. Maybe someone has had a similar problem. Share this post Link to post Share on other sites
