2003-2007 Powerstroke Low Temperature Thermostat & Housing (MMTS-F2D-03FL)

Note: This thermostat housing replaces the Ford Motorcraft RT-1169 thermostat.

A defective thermostat can lead to overheating and engine damage. Upgrade your 2003–2007 Ford 6.0L Powerstroke with the Mishimoto Low-Temperature Thermostat and CNC-machined aluminum housing. The thermostat activates at 185 °F, which is lower than the factory 192 °F, allowing coolant to flow sooner for improved temperature control. The 6061 aluminum housing provides a reliable, rust-resistant seal, making it ideal for trucks in warm climates or under extreme towing conditions.
