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.

Part come well packaged and was easy to install. Great machine finish and a much beefier part than the weak stock piece. Have been running it for almost 2 years without an issue. Well worth the money for the upgraded reliability.

I have had the cheaper stamped steel housings which seem to always warp and cause leaks. This housing is very solid and seals extremely well. I'm confident its the last one I'll buy.
