Report: Quick-Connect Fittings For Heater Hoses May Leak Engine Coolant
GMC Yukon Problem
Model Years Affected: 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999
Average Mileage: 155,400 mi (55,000 mi - 283,000 mi)
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.
