Built for OE-Style Heater Hose Service
Dorman 626-755 is designed for the heater hose inlet path on Silverado 1500 and Sierra 1500 trucks where the original hose assembly has aged, cracked, or lost sealing performance. The molded assembly uses EPDM, metal, and plastic materials to support durability in hot coolant and underhood temperature cycling. With a 1 in. end 1 inside diameter, 0.62 in. end 2 inside diameter, and quick disconnect attachment at one end, this part follows the factory-style layout needed for a clean replacement on the specified Chevrolet Silverado 1500 and GMC Sierra 1500 models. This part cross-references Gates 24479 for the same application.
Common Problems This Part Can Address
- Coolant seepage at a worn heater hose connection
- Cracked or brittle factory hose assembly
- Restricted heater flow from a damaged hose section
- Broken or weakened molded hose routing on the inlet side
- Fitment issues after replacing a failed OE heater hose assembly
Installation Notes and Tips
Verify the inlet-side routing, end diameters, and quick-disconnect connection before installation. 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.
Quality Assurance
Dorman 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. It is built to withstand extreme temperature changes for extended service life in the heater hose system.
