Temperature Guage shooting to ~~HOT~~ / Maintenance Manual?
After I drive a few miles, the temp gauge zooms to WAY HOT and I get a message in the display screen on the dash. I know to crank the heat when that happens, so I did. As soon as the heat starts up, the temp gauge immediately drops to normal levels. But I don't know what's causing it. Is it just a thermostat? Someone told me this SUV may have (2) termostats? Is that true?
If it's just a termostat, can I change it/them myself? I have a very good working knowledge of autos/trucks and a decent set of tools.
1) Is is just a termostat?
If so, can I do it myself?
2) Where can I find a very good maintenance manual for this SUV? I remember the Chiltons manuals from years ago. Is that the thing to get?
