2011-2025 Powerstroke Fleece Thermostat Housing Upgrade (FPE-FMC-TH-1125)

Fits

Eliminate coolant leaks from your plastic OEM or aftermarket thermostat housing on your 6.7L Power Stroke with the Fleece's Thermostat Housing Upgrade.  This upgrade is made from durable cast aluminum and works with all factory and replacement thermostats.  

What can often happen is the housing can crack leading to coolant leakage around the thermostat housing area, leading to a low coolant level, or the smell of coolant during engine operation or after operation.  This prompted Fleece to come up with the thermostat housing upgrade, which solves the problem and prevents future leakage.
