Inspect mating surfaces, seals, and adjacent heater circuit components for wear or contamination before connecting the new assembly. Because clamps are not included, reuse or source the correct hardware only if the vehicle application requires it. Confirm the hose follows the original molded path to avoid kinks or stress at the connection points.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDorman designs this HVAC heater hose assembly as a standard replacement part to match the fit and durability of the original assembly on the listed vehicles.
