Motorcraft Thermostat RT1201 for Ford & Lincoln — Vehicle-Specific Fit, Durable Construction

The Motorcraft RT1201 Thermostat is a premium aftermarket replacement thermostat engineered to restore correct engine temperature control for compatible Ford and Lincoln vehicles.

If your vehicle is running too cold, overheating, or showing fluctuating temperature readings, a properly functioning thermostat is often the simplest repair to restore stable engine operating temperature. The Motorcraft RT1201 is built to Motorcraft specifications and tested for durability and consistent performance so you can replace a worn or failed thermostat with confidence.

How does the RT1201 help engine temperature regulation?
