My steel OEM housing had been leaking for years. This fit a 2001 F350 7.3l. I had to buy different cap screws than the ones supplied with this housing the water pump on my truck did not have fine thread. None-the-less, no more puddle of antifreeze under my truck in the mornings.

$50 well spent and got rid of the leak caused by the flimsy, thin stock housing. This billet T-stat housing and Motorcraft F6TZ8575EA T-stat assembly work great together. Looks great too...

So many cool colors to choose from. Love the green, great job giving us so many choices. It's a great quality product.

Well designed, sealed perfectly, nice anodized finish.

Finally stopped my leak. I ordered a off-brand one from amazon because it was cheap. Would not seal no matter what I did. Gave up ordered one from Riffraff and a thermostat, fixed the leak and way better looking part.

Easy to install and perfect fit

Its well worth the money, as it will last a lifetime and you wont ever replace it. Built really well. The stock pot metal one is bound to need replacing as it will eventually pit. Clay I have a suggestion, you should make a Billet Lower Elbow as well.

It has only been installed a couple weeks, so time will tell for sure. Installed with Motorcraft t stat and gasket. No leaks so far. Seems much better than OE pot metal design.

Purchased this high quality part after a recommendation from Stephen Cox on YouTube. Quality manufacturing it’s too pretty to put on my 7.3 power stroke diesel. Considering purchasing the lower curved piece next.
