Report: Quick-Connect Fittings For Heater Hoses May Leak Engine Coolant
GMC Suburban 1500 Problem
Average Mileage: 164,500 mi (125,000 mi - 200,000 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.
