What It Helps Address

• Delayed coolant circulation after cold starts
• Temperature control issues that can affect heater performance
• Replacement needs on high-mileage Volkswagen, Audi, Porsche, or Mercury cooling systems
• Service repairs where the original thermostat temperature rating must be retained

Installation Notes and Tips

Verify the housing style before ordering, since the housing is not included. Confirm the 188-degree specification and compare the old thermostat to the replacement before installation. Clean the sealing surface thoroughly and install the included gasket/seal to help prevent coolant leaks. On Volkswagen Beetle, Jetta, Golf, and Passat cooling system service, inspect the thermostat housing and coolant condition at the same time.
