You need to make sure you don’t have a defective thermostat in your Powerstroke. If you do, this can cause overheating and internal damage to your engine. Save yourself the time, money, and hassle by investing in Mishimoto's High Temperature Thermostat with CNC Housing.

This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has a higher activation temperature (200°F) compared to the factory thermostat (192°F). The higher activation temperature restricts coolant flow longer to allow a quicker engine warm-up, making this thermostat ideal for use in cold climates. The CNC machined 6061 aluminum housing will provide a proper seal and will not rust over time. This thermostat and housing includes the Mishimoto Lifetime Warranty.
