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 Low-Temperature Thermostat! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has lower activation temperatures (189 F/196 F) compared to the factory thermostat (194 F/201 F). The lower activation temperatures allow 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. 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 include the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.Key FeaturesDirect fit for the 2011+ Ford 6.7L PowerstrokeLower activation temperature allows coolant to flow through the engine earlier, maintaining lower temperaturesIdeal for vehicles in warm climates or under extreme towing/driving conditionsMishimoto Lifetime WarrantyPurchase Includes(1) Mishimoto Thermostat(1) Factory-Style O-RingMishimoto Lifetime WarrantySpecificationsApplications2011+ Ford F-250 w/ 6.7L Powerstroke2011+ Ford F-350 w/ 6.7L Powerstroke2011+ Ford F-450 w/ 6.7L Powerstroke2011+ Ford F-550 w/ 6.7L PowerstrokeMishimoto Activation Temperature (F)189OEM Activation Temperature (F)194
