Heater Supply And Return Hose And Tube - Mopar (68251578AB)

The Heater Supply And Return Hose And Tube - Mopar (68251578AB) is a genuine OEM coolant circulation assembly engineered to manage both the delivery and return of coolant between the engine cooling system and the heater core. Manufactured to Mopar’s exact factory specifications, this complete assembly ensures efficient coolant flow, dependable cabin heating, and proper system balance under a wide range of operating conditions.

Constructed from high-temperature reinforced rubber hoses, corrosion-resistant formed metal tubing, and OEM-grade connection fittings, this heater supply and return assembly is built to withstand continuous heat cycles, pressure variations, vibration, and long-term exposure to engine bay conditions. Its durable construction helps resist cracking, swelling, leaks, corrosion, and premature wear for reliable service life.

Functionally, the supply line delivers heated coolant from the engine to the heater core, while the return line routes coolant back into the cooling system after heat exchange. Proper flow through both circuits is essential for effective cabin heat, windshield defrost performance, and stable engine temperature regulation. A worn or damaged assembly may cause coolant leaks, reduced heater performance, overheating concerns, or loss of system pressure.

As a genuine Mopar OEM component, this assembly is manufactured to precise factory bend geometry, hose lengths, connector sizing, sealing surfaces, and fitment tolerances for dependable compatibility with the original heating and cooling system layout. This helps avoid routing issues, connection leaks, or installation problems commonly associated with aftermarket alternatives.

Installation is recommended when repairing coolant leaks, replacing deteriorated heater hoses, resolving HVAC performance issues, or during major cooling system service. Proper inspection of clamps, seals, and coolant condition is recommended during replacement.
