Chevrolet 2500 Pickup Overheating and/or Coolant Loss Due to Leaking Quick-Connect Fitting

(17 reports)

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.

Eliminated couplers and threaded brass barbed connectors to engine block. Used truck bus high silicone heater hoses and left enough room to replace alternator with big frame 140 law enforcement alternator -
