I know, they run hot. Well, now that we have had some very cool nights in the 40's, the car will not warm up.. Perhaps the previous owner took out the thermistat?? (Mike, You Out There??). The needle will go to 12 O'Clock at idle.. But once driving it slowly drops just right past the blue (Still in the blue last night). If I put the heat on in the car, you can feel that it is cooler. Any thoughts?
