A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.0L cooling system with a Mishimoto Ford 6.0L Powerstroke High-Temperature Thermostat and 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. Like all of our Powerstroke Performance parts, this thermostat and housing includes the Mishimoto Lifetime Warranty.

Mishimoto Automotive (“Mishimoto”) warrants its products under this lifetime limited warranty policy (“Warranty Policy”). This Warranty Policy applies solely to: (i) Mishimoto Products purchased directly from Mishimoto or Mishimoto authorized dealers (each a “Mishimoto Product” and collectively, the “Mishimoto Products”) and (ii) the original purchaser of such Mishimoto Product (“Purchaser”). This Warranty Policy is non-transferable and all claims under this Warranty Policy must be accompanied by the original sales receipt.
