    Get yourself a 195 degree thermostat. I had a same problem in my truck. New thermostat solved my problem.

    Same thing with me. Im in Montana and it was around 7 degrees in 0ctober, and my heat would never get warm enough. So I got a 195 themostat, found out mine was stuck open when I took the old one off. Also to get your heat working quiker, just slip a piece of cardboard infront of your radiator and you're good to go. /forums/images/graemlins/truck.gif

    The Gauge is in the 100-150 range in winter.The 195º thermostat will be valid for the 6.2 Diesel engine?
    Thanks for the replys.

    Just go get an AC fan. They are wound differently. You'll either need to make a filter for the motor vent, or just leave it open and hope for the best. It's not too dusty out here, my dads been running his "open" for years.
