Detailed Description

This engine coolant thermostat is designed for vehicles that require a 188 degree OE Type Thermostat, including many Ford Taurus, Ford Escape, Ford Fusion, Lincoln MKZ, Mazda Tribute, and Mercury Milan applications.

Installation Notes and Tips

Verify the 188 degree temperature rating and match the thermostat dimensions to the original part before installation. Clean the thermostat housing sealing surfaces thoroughly and inspect the cooling system for contamination, damaged seals, or restricted coolant flow. Confirm vehicle-specific fitment for your exact year, make, and model before ordering.
