Description
Engine coolant thermostat designed to regulate coolant flow and maintain optimal operating temperature. Ensures efficient warm-up, prevents overheating, and supports reliable performance with a precise fit. 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.
