Detailed Product Information

URO 022121117C is an engine coolant thermostat housing for vehicles that use this OE-style cooling system layout. It is a direct-fit replacement for select 1999-2009 Volkswagen and Audi models, including 2006-2009 Audi A3 Quattro, 2004-2006 Audi TT Quattro, 1999-2005 Volkswagen Golf, and 1999-2003 Volkswagen Jetta. This part cross-references Dorman OE Solutions 902-920 and Gates CO34877 for the same application. The housing is engineered to match factory dimensions so the thermostat area and hose interfaces align correctly during service.

Common Cooling System Issues

• Cracked thermostat housing causing coolant leakage
• Warped flange surfaces that prevent a proper seal
• Loose or poor-fitting hose connections at the housing
• Failed housing replacement during coolant system repair
• Sensor-port related service on applications that use temperature sensor provisions

Installation Notes

Verify vehicle fitment before installation and compare the original housing to the replacement part. O-rings and gaskets are not included, so reuse only if serviceable or replace as needed during cooling system repair. Clean all mating surfaces thoroughly and inspect hoses, clamps, and nearby coolant components before reassembly.

Quality Assurance

URO backs this thermostat housing with a 24 month unlimited mileage warranty. The housing is built to OE dimensions and uses alloy or composite material to help maintain sealing integrity under normal cooling system conditions.
