ACDelco 84914057 Auxiliary Heater Outlet Hose Assembly, Molded Rubber

The ACDelco 84914057 is an auxiliary heater outlet hose assembly (also called an auxiliary heater hose or HVAC heater hose). It carries coolant to and from the heater core. It is a GM Genuine Parts item, and some GM Genuine Parts were formerly sold as ACDelco GM Original Equipment (OE).

Key Features:

• Molded hose assembly made of rubber, black
• OE classification, vehicle-specific fit
• End 1: 0.76 in inside diameter, 1.03 in outside diameter
• End 2: 0.6 in inside diameter, 0.88 in outside diameter
• No spring and no branches; clamps are not included

This hose replaces a worn or leaking auxiliary heater hose, so coolant keeps flowing through the heating system.
