Installation Notes and Tips

Compatible With 2003-2006 Ford Thunderbird and 2003-2005 Lincoln LS. Verify engine application and mounting-hole layout before installation. Transfer no hardware unless your vehicle setup requires it, since mounting hardware is not included. Clean the sealing surfaces thoroughly and inspect adjacent coolant hoses and clamps before reassembly. The thermostat opening temperature is 208 Deg. F, so confirm the replacement matches the original specification for your vehicle.
