A while back (probably last winter) I was driving a truck that needed a new thermostat, in what I thought was fairly cold weather. Reading TFA, I understand it wasn't really so cold. As long as the heater worked, I was fine. As soon as it started blowing cold air, I knew the thermostat had gotten stuck in the wrong position again. I figured out that I could simply slam on the brakes to solve this problem. In this fashion I was able to drive about 25 miles to a mechanic. The truck had a functioning radiator and appropriate coolant levels. The only thing wrong was the thermostat. Even in that configuration, the temperature gauge climbed into the "danger zone" if I neglected the brake-slamming trick.
