ACDelco Engine Coolant Heater Hose Assembly

The ACDelco Engine Coolant Heater Hose Assembly line includes heater hoses, also called HVAC heater hoses. They carry hot engine coolant between the engine and the heater core. That flow lets the cabin heating and defrost systems work as designed.

Key Features:

• Made to carry engine coolant through the heating circuit
• Built for the heat, pressure and vibration of a cooling system
• Assembly design helps keep routing and connections consistent
• Backed by the ACDelco brand, a name with a long history in replacement parts

A worn heater hose can leak coolant, lose pressure or restrict flow. Replacing it helps keep the heater and defrost systems working and helps protect the engine cooling system. Each part number in this line is sold individually. Choose the specific part number that matches your application.
