Well got a chance to look into my heating problem and checked the thermostat to be the culprit. Disconnected the lower radiator hose and sprayed some high pressure water in there to see if there was any gunk in there, not really much at all. Now looking at the thermostat and it is a 160 degree, I thought it should have been a 180, the truck is running about 140 without a thermostat until I bye one. What you Bolters take on running the 235' without a thermostat for the time being just around town? It does seemed to be running cooler.
