The issue I'm experiencing is my heater goes hot...melt your face hot, and then after about another 5-10 minutes it starts to cool down and then it goes back to hot. Now, I don't hear any clicking sounds and I have yet to check the level in the radiator. I will do this in a few hours after it cools down. Just wondering if it could be the t-stat if the radiator is full? Any ideas welcome here.
Thanks in advance.
