Product Details and Specifications

The Dorman 626-612 heater hose assembly is engineered as a branched coolant hose with three barbed attachment points, each having a 0.5 inch inside diameter. The hose ends measure 0.63 inches outside diameter, ensuring compatibility with factory connections. This regular grade hose assembly does not contain springs or protective sleeves but includes clamps to facilitate a secure and leak-free installation. The molded assembly shape is designed to match the OEM routing for efficient coolant flow within the HVAC system.

Compatible Vehicles and Applications

This heater hose assembly is compatible with a range of Audi and Volkswagen vehicles, including the Audi A3, A3 Quattro, Q3, Q3 Quattro, TT, and TT Quattro, as well as Volkswagen Beetle, CC, Eos, Golf, GTI, Jetta, Passat, Tiguan, and Tiguan Limited models. The Dorman 626-612 is intended for use in HVAC systems requiring a branched heater hose assembly with the specified dimensions and pressure rating.

  • Resolves heater core coolant leaks
  • Replaces cracked or damaged heater hoses
  • Prevents coolant loss and overheating issues
  • Restores proper heater function and cabin warmth
  • Eliminates coolant contamination from hose failure

Installation Notes and Tips

Before installation, ensure the engine is cool and the cooling system is depressurized. Remove the old heater hose assembly carefully to avoid damage to surrounding components. Use the included clamps to secure each barbed end firmly, preventing leaks. Verify that the hose routing matches the original configuration to maintain proper coolant flow and avoid kinks or stress points.

Dorman parts are manufactured to meet or exceed OEM specifications for fit, form, and function. The 626-612 heater hose assembly undergoes quality checks to ensure durability and performance under normal operating conditions. While specific warranty details may vary, Dorman typically offers limited warranties covering defects in material and workmanship.
