Ok, I replaced the thermostat, and it ran fine in parked, a/c was on and it was fine. Then when i started to drive it, it went up, and never came down. I am trying to figure out the fan thing and coil thing? Is it the fan in front(looks like a little house fan) or the huge fan in back? And if I am standing the front of the car do I feel left or right? and about how big is this coil? Thanks for your help!
