A heater hose carries coolant between the engine and the heater core, so a leak here lets coolant escape from the cooling system. Coolant drips or crusty residue near the hose, a soft, swollen or cracked section, a falling coolant level, or weak cabin heat are signs the hose may need replacing. Other cooling-system parts can cause the same symptoms, so confirm the source first. Country of origin: Mexico.

V8-5.3L: Chevrolet Avalanche (2007-2013), Chevrolet Avalanche 1500 (2005-2006). Each listed application uses one hose. See the Buyer's Guide tab for the full list.
