Installation Notes and Tips

Verify the VIN, engine designation, and model year before installation, especially on Audi A4 and Audi A4 Quattro vehicles with sensor-equipped thermostat housings. Inspect the sealing surface, coolant passages, and hose connections for wear or contamination before assembly. Replace the gasket seal during service and confirm the thermostat housing is seated evenly to help prevent coolant leaks.
