      Great Replacment

      When it came time to replace the thermostat, I decided it would be best to replace the housing rather than fight the corrosion on the original. This thermostat fit perfect, looks great, and an added bonus, has a fitting for adding in an additional sensor, i used this for my auto meter temp gauge, but it could also be used for a fan controller.

      This looks very good, there is 2 issues I have .#1 the ad never said this was a Mr Gasket product,I had read some bad reviews on another site about there water neck and would not have chanced buying this if it was stated in the ad that it was a Mr Gasket product.#2 this is billed as fitting a 75-95 302, that is not true the bypass hose on mid 85 and up has a 5/8 end on the water neck side not 1/2 like the earlier years I already had the 5/8 style hose so I had to get a new 1/2 style I haven't put antifreeze in it yet so we will see if the reviews are true or not .

      Fit is perfect. chrome flaked off in a few months and started to yellow. I expected more for the price I would not recommend.

      Looks great, hose fitment issue.

      I bought this new water neck because I was changing the thermostat and wanted a little bling. It looks great, the only issue is the stock bypass hose is too big for the inlet. I bought the Ford Motorcraft By-Pass Radiator Hose (79-93 5.0L) but the inlet on the neck is smaller than stock. Wish I would have known that before I wasted 10 bucks on this hose from American Muscle.

      Chrome Water Neck

      The chrome fell off in less than a month. This is the only product I have purchased from American Muscle that was junk.

      Excellent finish, poor details

      Excellent finish on sealing surfaces, the chrome looks great under the hood. The parts fit together great and a simple install; however, this would have been a 5 star rating, but what should've been a 1 hour install turned into a 3, when I found out the the new water neck uses a different bypass hose configuration and had to go back to the parts store. Product specifications and install guide failed to mention this important detail.

      Nice piece

      I was hoping to find this part in a satin finish, but this had to do. I opted for the "direct-fluid style" sensor for my electric fan digital controller and needed the added port. This item fit the bill and worked well. One small complaint - while all the fittings I used were correct, the amount of threads anything would go in (the included plug as well) were much less that one would hope for. It seemed like it should screw in much deeper, but so far no leaks (with Teflon tape used). On my car I would have played heck trying to use the supplied hex-head bolts, but nice they included them. I reused the originals. If you need one, this sure is nice otherwise. The chrome seems very solid and the part is weighty and feels very, very solid.

      chrome water neck

      i noticed my water neck was all rusty and ugly when i was changing my water pump and hoses. i tried to combine it with AM's mishimoto racing thermostat. However the shop that i took my car to said that it didnt fit with neither the stock nor chrome waterneck so i bought a stock thermostat from autozone. anyway the waterneck is awesome and looks great!

      It looks nice but it is twice as heavy then the stock one. I am still in the process of rebuild, so I did not have a chance to fit it yet.
