The Mishimoto MMTS-F2D-11H Primary Coolant Thermostat (High-Temperature) for your Ford 6.7L Powerstroke improves the reliability of your cooling system. A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.7L cooling system with the Mishimoto High-Temperature Thermostat.

The MMTS-F2D-11H 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.
