Heater Hose, Supply – Mopar (55056966AA)

The Mopar Heater Hose, Supply (55056966AA) is a Genuine OEM cooling system component designed to deliver heated engine coolant from the engine to the heater core. This hose plays a vital role in the vehicle’s cabin heating system by allowing hot coolant to circulate through the heater core, where heat is transferred to the air that enters the passenger compartment. Manufactured to Mopar’s strict factory engineering standards, this supply hose ensures consistent coolant flow and dependable heating performance.

Constructed from reinforced heat-resistant rubber with internal strengthening layers, the hose is designed to withstand the demanding conditions of the engine compartment. The materials are engineered to resist high temperatures, pressure fluctuations, and exposure to coolant and engine heat. The reinforced construction maintains flexibility while providing durability against cracking, swelling, and long-term wear caused by vibration and thermal cycling.

The 55056966AA heater supply hose is engineered as a vehicle-specific direct-fit component, matching the original factory routing path, hose length, bends, and connection diameters used in Mopar heating and cooling systems. Maintaining OEM specifications ensures proper coolant flow between the engine and heater core while allowing secure connections to surrounding cooling system components. Aftermarket hoses that do not follow factory design specifications may lead to leaks, restricted coolant flow, or installation complications.

For professional technicians, installing a Genuine Mopar heater supply hose helps maintain factory cooling system integrity and reliable cabin heating performance. For experienced DIY vehicle owners, the OEM hose design simplifies installation since it connects directly to the original fittings and mounting points without requiring trimming, adjustments, or modifications.

A properly functioning heater supply hose allows heated coolant to circulate efficiently through the heater core, supporting consistent cabin warmth while maintaining stable coolant flow within the engine’s cooling system.

• Genuine Mopar OEM heater supply hose
