Mishimoto engineers know you love your Ford which is why we've developed a line of Powerstroke performance parts. A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 7.3L cooling system with a Mishimoto Ford 7.3L Powerstroke Low-Temperature Thermostat! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto low-temperature thermostat has a lower activation temperature (189°F) compared to the factory thermostat (195°F). 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 Powerstroke performance parts, this low-temperature thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship. Whether your Ford is stock or modified, trust Mishimoto and our line of Powerstroke performance parts to keep your Powerstroke cool.
