Dieselsite Billet Aluminum Thermostat Housing

Fits: 1999-2003 Ford Powerstroke 7.3L

Torque Specs for Thermostat Housing bolts: 100-110 in-lbs

If you've ever tried to change out your thermostat in the Powerstroke Diesel, you'll find that the factory thermostat housing leaves much to be desired. It is a very poor quality stamped steel that doesn't always seal properly when replacing your thermostat and they rust very quickly. The OEM housing is also considered to be "disposable", meaning it's designed for a single usage. If it has to be removed, it must be replaced. The flanges bend under the load of the bolts. The Dieselsite Billet housing is designed to be used over and over again and give you years of trouble-free service.......and it looks great too!

Please check yours for style. Older E-Series have a different style housing.

*If you choose the Dieselsite Stainless Steel mounting bolts with your new Billet Aluminum Thermostat Housing, you are furthering your protection against corrosion. We have experienced that in addition to the stock thermostat housing having corrosion concerns, the stock steel mounting bolts also are susceptible to excessive corrosion. Fully protect against corrosion with these Stainless mounting bolts.
