Quality engineered to resist corrosion and coolant leaks, the Dorman HVAC Heater Hose Assembly is designed to limit the possibility of overheating and subsequent engine damage. Original HVAC heater hose assemblies typically require replacement due to cracks in the original Y-connector plastic construction. Our OE FIX repair solution addresses this common failure mode by upgrading the Y-connector material to aluminum for increased durability and a longer service life. Plus, Dorman Heater Hose Assemblies are application-specific, and ensure the easiest, cost-savings alternative to replacing the entire assembly. All Dorman products are engineered in the United States and backed by 100 years of automotive aftermarket experience. Our solutions are thoroughly tested and inspected, and if you experience any difficulty installing or using our parts, we have a dedicated technical support team of ASE Blue Seal certified professionals ready to help.
