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.

    I have had the connector replaced by a GM mechanic twice in three years. I bought(4) connector none stopped the leak. I then went to the repair site and the info given states to replace the connector with a threaded hose connector from Advance Auto Parts. Will ask for this part at Advance Auto Parts.
