What It Helps Address

• Engine running too cool or too warm due to thermostat wear
• Delayed coolant flow regulation during warm-up
• Temperature fluctuation in the cooling system
• Cooling-system service on OE-specified 170F applications
• Replacement of a thermostat with a worn or leaking seal

Installation Notes and Tips

Verify the 170 degree F opening temperature and confirm the sealing flange dimensions before installation. Replace the thermostat only after the cooling system has been drained and the housing surface is clean and free of old seal material. Use the included rubber O-ring seal and follow the vehicle service procedure for proper coolant refill and air bleeding.
