The Mishimoto MMTS-F2D-03L Low-Temperature Thermostat for your 03-07 Ford 6.0L Powerstroke will improve the reliability of your cooling system. A defective thermostat can result in engine overheating and potential internal damage. Designed as a direct replacement for your aged factory unit, the Mishimoto thermostat provides a lower activation temperature (185 Degrees Fahrenheit) compared to the factory thermostat (192 Degrees Fahrenheit). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates or under extreme towing/driving conditions. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.


  • 185º Activation Temperature
  • Ideal For Warmer Climates & Towing
  • Maintains Lower Engine Temperatures

Note: This thermostat requires the use of the Ford Motorcraft RT-1169 thermostat housing. An early-design thermostat housing was superseded with this housing, so some vehicles might have the early-design housing.

Purchaced this thermostat thinking it would lower my engine coolant temperature, I use a autometer gauge and DID NOT see a noticeable decrease in temperature. Not worth the money
