Dorman 626-780 Heater Hose Assembly
Dorman 626-780 is a replacement HVAC heater hose assembly for select Chevrolet Silverado 1500 and GMC Sierra 1500 applications. It is built with EPDM, metal, and plastic components and uses a molded assembly layout with a protective sleeve for added durability in demanding underhood conditions.
Key Features
- Direct replacement HVAC heater hose assembly for the outlet position
- EPDM hose material helps resist heat and coolant exposure
- Molded assembly design with a 90-degree maximum bend angle
- Protective sleeve attached for added abrasion and heat protection
- Quick disconnect connection on end 2 for OE-style serviceability
- Black and silver finish with molded routing for a clean factory-style fit
- Cross-reference: Gates 24478 for the same application
Detailed Description
This Dorman heater hose assembly is engineered to match the fit and durability of the original heater hose routing on select trucks. It is designed for 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models at the outlet position, with additional coverage for 2019 Chevrolet Silverado 1500 LD and 2019 GMC Sierra 1500 Limited outlet applications. The assembly measures 37.5 inches centerline length, with 0.82-inch inside diameter at end 1 and 0.97-inch inside diameter at end 2, and it is rated for up to 100 maximum working pressure.
Use Dorman 626-780 when replacing a worn, cracked, or leaking heater hose assembly on Silverado 1500 and Sierra 1500 trucks. The molded shape, EPDM construction, and quick disconnect end help maintain proper coolant flow and factory-style routing in the HVAC system.
What It Helps Fix
- Coolant leaks at the heater hose assembly
- Cracked or heat-aged hose material
- Damaged quick disconnect connection at the outlet side
- Poor hose routing caused by a deformed molded assembly
- HVAC heater circuit flow issues related to hose deterioration
Installation Notes and Tips
Verify the outlet position and connection style before installation. Inspect mating surfaces, seals, and adjacent coolant lines for wear or contamination before connecting the new assembly. Because clamps are not included, reuse or source the correct hardware as needed for the vehicle application. Confirm clearance around the protective sleeve and follow the vehicle service procedure for coolant refill and air bleeding after installation.
Quality Assurance
Dorman designs this replacement heater hose assembly to match OE fit and durability expectations for the listed vehicles. The construction uses materials selected to handle repeated temperature swings and everyday underhood exposure.
