I have a leak that is near the heater core, but I can’t see where it originates. I don’t want to remove the dash unless I’m sure the heater core is the problem.
I rigged a crude pressure test by sealing one opening and blowing into the other. I seamed to seal, but it may have a slow leak. I use the defroster every day and haven’t seen any fog on the inside of the windshield that would indicate a coolant leak in the core.
Could it be coolant leaking from the back of the manifold or maybe even the head gasket? The car leaks just enough to empty the overflow tank every 400 miles. The leak is not visible and I don’t think that it is any of the heater hoses.
Any help is greatly appriciated!
