What It Helps Address

• Engine running too cool or taking too long to reach operating temperature
• Temperature fluctuation caused by a worn thermostat
• Cooling system service on Ford and Lincoln vehicles with a 190F specification
• Restoring proper coolant flow control after thermostat replacement
• Air trapped in the cooling system during thermostat service

Installation Notes and Tips

Verify the OE temperature specification before installation, especially on Ford F-150, Ford Explorer, Ford Edge, and Lincoln Navigator applications that may use different thermostat calibrations by engine or model year. Inspect the housing and sealing surfaces carefully, and replace the seal or gasket if your application requires one. The jiggle pin weep hole should be oriented to help air escape during filling and bleeding.

Use the vehicle service procedure for coolant refill and air bleeding after installation. Confirm fitment by year, engine, and cooling system configuration before ordering.
