I started the truck because it is -10 below out and wanted a warm truck to get into. I came back after 20 minutes and found that the heater was blowing freezing cold air, and my engine was over heating. Someone said it sounds like a thermostat problem and if it is how do I replace it? Any help would be very helpful!
Thanks.

Let the engine cool off, then drain it down about a gallon, there is a draicok on the bottom of the radiator, then follow the upper radiator hose to the engine, there you will find the thermostat at the end of the hose, unbolt the two bolts. Leave the hose attached to the housing. Scrape old gasket from both mating surfaces, install new thermostat, spring towards the engine. Install the gasket, snug the housing bolts! Not to tight and bring the housing down evenly. Refill the coolant and that's it!
