Description

The Fleece FPE-FMC-TH-1125 Thermostat Housing Upgrade will replace the stock plastic thermostat housing on your Ford 6.7L Powerstroke. A common complaint is that coolant leaks around the thermostat housing area, a low coolant level, or the smell of coolant during engine operation or after operation. This is commonly caused by a cracked thermostat housing that will result in a coolant leak, potentially leading to overheating and engine damage.

If you suspect a leak, carefully inspect your thermostat housing for cracks or damage. Pressure test the coolant system to see if it maintains pressure, and look for leaks at all split lines, including the thermostat housing and coolant crossover manifold.

Upgrade your plastic factory or aftermarket engine coolant thermostat housing on your truck with a more durable cast aluminum unit. This direct-fit replacement thermostat housing works with OE and aftermarket replacement thermostats. This kit comes with new O-rings. Get direct factory replacement for the weak plastic housing that can become brittle over time wen you install the Fleece Performance thermostat housing upgrade.

Features:
  • Includes O-Rings
  • Direct-Fit Replacement
  • CNC-Machined Housing
  • Cast Aluminum Construction
