Re: Overheating issue - I am stumped!
Is your new thermostat a "fail safe " one. I have tried them in the past and they do what you are describing.Also they will stop working all of a sudden and stick open or even closed. Try putting one of the cheap ones in. Make sure it has a jiggle valve in it . That allows the air to pass through it so you dont get air bubbles in your system.Hope this helps. Gord
