As much as hauling power and engine performance is important in your GMC Sierra, the little things also matter, too. Heater hoses connect the engine block to the heater core and deliver warm engine coolant to the core. A leaking hose eventually leads to engine overheating, while a blocked hose means no hot air circulates inside your truck when you need it most. Trust AutoAnything for GMC Sierra replacement heater hoses that perform better and last longer, too. And our 1-Year, Lower Price Guarantee is unbeatable.
