Problem Description and Possible Solution
The quick-connect fittings for the heater hoses tend to leak engine coolant. This problem commonly occurs because the metal housing has become brittle, which can break and cause leaks.

Heater hose quick connect coupling rotted out and broke off flush with the engine. Had to buy an $80 drill and thread repair tool kit from Napa. Pay no attention to the videos on YouTube Just go to Napa and by the repair kit and a new coupling. Kit also comes with a splined easy out that you may be able to pound down and remove the broken piece with. I had no luck with that. Napa part # is 77-4029
