Common Repair Uses

• Coolant leaks at the thermostat housing or outlet
• Cracked plastic housing from heat cycling
• Warped sealing surfaces that cause seepage
• Cooling system service on VW and Audi 2.0L applications with outlet-style housings
• Replacement of a damaged OE-style coolant outlet on CBFA and CCTA engine designations where listed

Installation Notes and Tips

Verify engine designation and fitment before installation, especially on Volkswagen Beetle, Jetta, Golf, Passat CC, and Audi A3 applications with outlet-specific notes. Because no gasket, seal, bolts, or O-rings are included, transfer or source the required sealing components separately as specified by the vehicle service procedure. Inspect the mating surfaces, coolant hoses, and adjacent plastic fittings before reassembly to reduce repeat leaks.

Quality Assurance

Dorman designs this replacement coolant outlet to match OE fit and durability expectations for the listed vehicles. The housing is built to withstand extreme temperature changes, supporting long service life in demanding cooling system conditions.
