Fought the stock leaking thermostat housing for years. I can not remember a time when I did not have anti-freeze crust all over the area. Bought this and used a good thermostat sealant around the edge and no more leaks. Nice part!!

Worked great

Well built perfect fitting product from RiffRaff and a good upgrade to get rid of the factory stamped steel one.

Probably overkill , but I had to replace OEM that was pitted, corroded. A little price to pay for some Bling that only you will probably see. Thanks, Riffraff

Very nice product is always what to expect from Riff Raff Diesel.
Counter bored bolt provisions with stainless hardware make a nice addition to the billet housing which is a great improvement over the stock housing. Be sure to purchase the correct size Allen Hex for the bolts!

Very nice part to replace my rusted oem part. Looks nice too

Bought a truck that had an unbranded aluminum thermostat housing on it and previous owner appeared to have drilled holes in it for some reason? Bought this to replace it. Excellent fit and excellent sealing. High quality.

much better than stock

Although I was ordering a water pump for my '97 F350 I was still able to order this thermostat housing which is actually for the later model SD' a. I still wasn't reverting to the stock housing so some research and another trip to the parts store and I found a hose that worked. It's a little close to the belt but so far no impact and no leaks.
