A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.7L primary cooling system with the Mishimoto Ford 6.7L Powerstroke High-Temperature Thermostat! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has higher activation temperatures (199°F/206°F) compared to the factory thermostat (194°F/201°F). The higher activation temperatures restrict coolant flow longer to allow a quicker engine warm-up, making this thermostat ideal for use in cold climates. Pair this thermostat set with the Mishimoto 6.7L Powerstroke Aluminum Primary Performance Radiator for a complete cooling system overhaul. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
