The Mishimoto low-temperature thermostat set for Ford 6.4L Powerstroke lowers activation to 187°F/197°F compared with factory 192°F/203°F, allowing coolant flow earlier to maintain reduced engine temperatures. Sold as a pair with a replacement gasket, this direct-fit option is suited to warmer climates or heavy towing and complements Mishimoto radiators for improved cooling control.
