• Leaks at the thermostat housing interface
• Air trapped in the cooling system after service
• Delayed warm-up or unstable cabin heat output

Installation Notes and Tips

Verify the OE-specified temperature rating before installation and inspect the mating surfaces for corrosion or residue. This assembly does not include bolts, gasket or seal, or mounting hardware, so confirm all required service parts are on hand before beginning the repair. Follow the vehicle service procedure for coolant refill and air bleeding to help prevent trapped air in the system.
