I changed out the entire t-stat housing over the summer which came with a t-stat installed. Everything was working okay until the cold weather hit. Now the temperature gauge will only go up one line and the heater blows mildly warm air. The gauge does go up to where it normally did before the housing change but only after driving hard for a while.
Could this be a sign of a stuck open t-stat? All fluid levels are good in the bottle. I'm hoping it isn't water pump or heater core related. I have no smell in the cabin or any frosty windows so I'm kind of leaning away from the heater core. Could the t-stat that is in the truck possibly be a higher temp stat?
I have a factory Motorcraft t-stat that I'm going to put in but am trying to think ahead in case that doesn't do the trick.
