running too cold

The "problem" you are describing is not a problem. All the Mopars I have owned over the years (40), except one, ran the temp gauge at the left edge of the normal range. That one got to the middle of the gauge. It was a 360 in a 71 Sport Fury. By and large, Mopars don't run in the middle of the factory gauge, that's a Chebbie/Phord thing. Mopars are generally steaming by the time the gauge gets that far. If you want heat out of a slant either block the radiator with cardboard or tap the rear of the head for the heater hose. I'm sorry to hear you are going to have to suffer through your cold weather. It's 18 and snowing here with a wind chill of -2 degrees. :-({|= Hope this helps.
