Upgrade the weak factory plastic thermostat housing on your 6.7L Powerstroke with the Fleece Performance Thermostat Housing Upgrade. Designed as a direct replacement for 2011-2025 Ford Super Duty applications, this cast aluminum housing offers improved durability, leak resistance, and long-term reliability over factory or aftermarket plastic units that can become brittle over time.
Coolant leaks, low coolant levels, and overheating concerns are common signs of a failing thermostat housing. Fleece engineered this upgrade to eliminate those weak points with a heavy-duty aluminum construction that installs in the factory location and works with OEM or replacement thermostats. New O-rings are included for a complete, leak-free installation.
