ACDelco HVAC Heater Outlet Pipe Assembly

The ACDelco HVAC Heater Outlet Pipe Assembly (also called a heater outlet pipe, heater hose pipe or heater core outlet tube) carries engine coolant from the heater core back to the cooling system. It is part of the heating circuit that supplies warm air to the passenger cabin and supports defrosting.

Key Features:

• Replacement assembly for the heater outlet coolant line in the HVAC heating system
• Made by ACDelco, the GM-affiliated parts brand, for dependable fit and function
• Helps keep coolant flowing so the heater delivers steady cabin heat
• Replaces worn, corroded, leaking or damaged heater pipes and lines
• Built to hold up to the heat, pressure and coolant exposure of the engine bay

Choose the part number that matches your application. Replacing an aging heater outlet pipe can prevent coolant leaks and restore consistent heater performance.
