ACDelco Molded HVAC Heater Hose Assembly

The ACDelco Molded HVAC Heater Hose Assembly is a pre-formed heater hose, also called a molded heater hose or coolant hose. It carries engine coolant between the engine and the heater core. This lets your vehicle's heating and defrost system work reliably in cold weather.

Key Features:

• Molded construction holds a consistent shape for a clean, kink-resistant routing
• Made from flexible, durable rubber designed to handle engine heat, coolant exposure, and pressure cycling
• Engineered as a direct-replacement part for a worn, leaking, or collapsed heater hose
• Backed by the ACDelco brand, a name known for quality replacement parts for domestic and import vehicles

Replacing an aging heater hose helps prevent coolant leaks and overheating. It also helps keep cabin heat steady. Inspect hose clamps and fittings at installation, and top off or flush the cooling system as needed after the repair.
