Mishimoto engineers know you love your Ford which is why we've developed a line of 2011–2016 Ford 6.7L Powerstroke performance parts. A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 2011–2016 Ford 6.7L Powerstroke primary cooling system with the Mishimoto 2011–2016 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 2011–2016 Ford 6.7L Powerstroke Aluminum Primary Performance Radiator for a complete cooling system overhaul.
