Fleece Performance Cast Aluminum Thermostat Housing Upgrade for Select 2011-2025 Ford F-250/F-350 (6.7L)

Fits select 2011-2025 Ford F-250 and F-350 Super Duty trucks (6.7L Power Stroke).

Replace the fragile factory plastic thermostat housing on your 6.7L Power Stroke with this high-strength cast aluminum upgrade from Fleece Performance. The original equipment plastic housing is a known failure point, frequently becoming brittle and cracking over time. These cracks lead to coolant leaks, low coolant levels, and potential engine overheating. This direct-replacement component provides a permanent solution, maintaining a reliable seal where the thermostat housing meets the coolant crossover manifold.

This housing is a drop-in upgrade designed to work seamlessly with all factory and aftermarket thermostats. The kit includes new O-rings to ensure a professional, leak-free installation. Whether you are addressing an active leak or performing preventative maintenance during a coolant flush, this aluminum housing eliminates the risk of plastic fatigue.
