The Mishimoto high-temperature thermostat for the Ford 7.3L Powerstroke is a direct-fit replacement designed with a higher activation temperature of 205°F versus the factory 195°F. By restricting coolant circulation longer, it promotes faster engine warm-up—helpful in cold climates—and improves thermal management during warm-up. The thermostat is covered by Mishimoto’s Lifetime Warranty for assured quality.
