Don't Let a Leaking Heater Hose Connector Leave You Stranded.

One of the most common failure points on many GM trucks and SUVs is the plastic heater hose connector. Over time, the constant cycling of hot and cold coolant, combined with engine vibration, causes the factory connector to become brittle and crack. This leads to coolant leaks, loss of cabin heat, and potentially severe engine overheating.
