I recently changed out the water pump, thermostat and thermostat stat housing on my 2000 F250 7.3 diesel. The old thermostat housing was not as rusted and pitted as I expected but this aluminum unit from Riffraff will ease any future worries about rust and it comes with stainless steel bolts.
I also bought new bolts for the water pump.. I'm happy with everything.

Perfect fit, new bolts that are included are nice

Superior quality really impressed with it and wonderful stainless steel hardware included shipped on time. I’m on the other side of the country so it took seven days really impressed with Riff Raff diesel and I’m gonna continue to purchase from you. Thank you very much..

Riffraff is the go to for sweetening up the 7.3

Well done RR.

Bought this and a fan clutch and received great customer service and responded to my emails within a couple of hours, extremely satisfied and will use this riffraff again for parts on my ps.

Glad my stock housing came out easy, and this product not only looks amazing but is definitely quality and will last!

The factory housing tends to rust and leak after many years exposed to the elements. This housing is much better and has a beautiful finish on it preventing corrosion. The fit is perfect and it looks good too. If your housing is leaking this is the best option when replacing it.

Replaced all my cooling components when my water pump blew and while I had it apart, I wanted to spruce up the engine bay with this T-stat housing. It gives me much more confidence than the factory 300k mile steel housing.

Perfect fit and hardware. Dresses up that ol 7.3.
