        Low quality ford product

        This came new in box in worse condition than the leaking Mr Gasket I am replacing. I have no idea ford quality control was so lacking. This product should not have even made it out to a customer. Be prepared for a VERY rough finished product. You will not be happy with the quality

        Worth the price

        The Ford Performance 90 Degree Thermostat Housing is a much higher quality piece than most of the aftermarket parts I looked at but the fit is where the real difference is. It fits like a glove unlike several if the aftermarket parts I tried and returned

        High quality

        I tried multiple brands t-stat housings all of them leaked or ended up leaking. The Ford performance one here was perfect no leaks, than goodness. Worth the extra money for sure!

        Best Housing

        I should have bought the Ford Performance t-stat housing in the beginning, instead of wasting my time and money on cheap aftermarket. I highly recommend this Thermostat Housing.

        Fit well

        Fit was great. Used a motorcraft thermostat that fit great. Thermostat was inserted to housing and a little twist and it would seat perfect. Made install easy because thermostat would not fall out. I used a gasket from another supplier that was adhesive on one side so it lined up great. Hasn't leaked at all.

        as good as new!

        this housing is better then whats available from aftermarket, just be prepared to do some cleanup, I'm having mine powder coated chrome and another powdered in wrinkle black to match each of my cars under hood treatment. I wish it came drilled and tapped as an option.

        I URGE you to purchase this and not.....

        A knockoff brand. Don't even bother going the cheap budget route or you'll be sorry you did. Last summer I purchased an aftermarket piece out of desperation (Amazon) and needed it ASAP for track day. Well, it leaked. I couldn't see anything wrong with it until I put a straight edge to it. So, learn from my mistake and buy the Ford unit. When you open the box, you'll see the machining and quality are even better than what they used in the 80's. Want another tip? If it's a roller 5.0, toss the o-ring and don't use a gasket. Smear high-temp silicone on the intake side AND on the housing's side. Let it set for a day. Done. Hope this helps someone else.

      3 Top Rated Questions

      does this thermostat housing has the provision drilled out for the temp sensor for the use of aftermarket fans?

      • The Ford Performance 90 Degree Thermostat Housing does not have a pre drilled and taped hole for the sensor.

      Helpful (3)

      What is used to plug the hole in the top of the housing?

      Does this include a replacement gasket for the housing?

      • Unfortunately, this will not come with the gasket. This package will only include the housing itself.
