  HEATER SUPPLY AND RETURN

  The Unified Highway for Thermal Comfort
  The heater hose assembly is responsible for the high-pressure transport of hot coolant from the engine block to the heater core and back. The Genuine Mopar Heater Supply and Return Hose and Tube (55038042AK) is a combined assembly engineered to maintain consistent cabin heat without compromising engine cooling efficiency. While aftermarket "cut-to-fit" hoses often create turbulence or rub against neighboring engine components, this genuine Mopar assembly is factory-molded to the exact 3D geometry of your engine bay, ensuring an unobstructed flow path.

  • Hybrid Metal-to-Rubber Construction: This assembly utilizes precision-bent aluminum tubing fused with high-durometer EPDM rubber. The rigid metal sections are strategically placed to withstand high heat near the exhaust, while the rubber sections provide the necessary flexibility to absorb engine torque and vibration.
  • Electrochemical Degradation (ECD) Resistance: Modern cooling systems can generate internal electrical charges that cause standard rubber to pit and crack from the inside out. This Mopar assembly features a proprietary internal lining that resists ECD, preventing the microscopic "pinhole" leaks that lead to mysterious coolant loss and overheating.
  • Zero-Kink Molded Geometry: Unlike "universal" flexible hoses that can collapse or kink at sharp bends, the 55038042AK is heat-set to its final shape. This ensures that your heater core receives a full, high-velocity volume of coolant, providing "instant-on" heat even in sub-zero climates.

  Why Choose Genuine Mopar?
  Choosing the Genuine Mopar Heater Supply and Return Hose and Tube (55038042AK) ensures that your vehicle’s heating system remains a sealed, high-pressure environment. Aftermarket assemblies often feature "approximate" bracket locations that can cause the assembly to rattle or chafe against the firewall.

  • The Ultimate Engineering Evolution: This part number (Revision AK) represents the most current factory-authorized design. It incorporates the latest material refinements to replace and supersede all previous iterations (including AE through AJ), ensuring you receive the most durable version of this component ever produced.
  • Pre-Crimped Structural Integrity: Every connection point between the rubber hose and metal tubing is secured with a factory-calibrated, high-pressure crimp. This eliminates the "blow-off" risk associated with manual hose clamps used on piece-meal aftermarket setups.
  • Surgical Fitment Guarantee: As an Authentic Original Equipment (OE) Part, this assembly aligns perfectly with the factory quick-connects and heater core inlets. This "no-stress" fitment prevents the cracked heater core nipples that often result from "forcing" ill-fitting aftermarket hoses into place.
  • Factory-Backed Reliability: Every Mopar heating component is backed by a Manufacturer-Backed Warranty. It undergoes rigorous burst-pressure and 150,000-mile endurance testing, offering a level of interior comfort and mechanical security that independent brands simply cannot match.
