im not sure why it comes on.. but when i drive for like 2 minutes, it comes on. I checked Anitfreeze and it is fine. My dad checked it.. he sed it was fine also. My engine temp is usually right in the middle if not lower. It usually takes a while for the guage to get in the middle like today.. sat running for 10 minutes (Canadian weather.. light snow) then i got in and drove for 30 seconds.. the line still wasnt near the middle.. any thoughts?
