In hindsight, I should ave bought the OEM part of even the Ford Racing part. After I put this on there were small leaks from where the parts screw in that the hoses connect to. I ended up using plumbers tape to get it to stop leaking. I have no idea who that will hold up in the long run, but it's not leaking. If it does leak in the future I'll just buy the OEM part.

The thing looks fine, and the hoses all fit without leaks, ditto for the beefy gasket which is supplied. FWIW the two mounting bolts require an allen wrench. The wrench I have that fit was marked 5.5... I guess that's millimeters, but not sure.Problem: see that fake-looking threaded "freeze plug" in the pic? I thought it was for bling or something. Nobody tells you to seal the threads on that thing. I fired my car up and coolant is hissing out of that thing... I'm going to have to remove and reinstall the part. Too bad they don't give any instructions about sealing the threads on that thing before installing. In fact, if you're a newb be warned that there are no instructions at all.Update: plumber's tape and the freeze plug doesn't leak.Head's up: if you don't have a diagram of how your serpentine belt goes on, you better make one. Removing the serpentine gave much better access to the tstat housing. If you have AC, the AC lines go over the top of the housing, so the entire housing must come off to seal that freeze plug. $#@!I guess, given that the part is so inexpensive, that one can't go wrong in buying it. It's one third the price of the OEM part, and comes with a serious gasket, just make sure to seal that threaded freeze plug in before installation.Use that gray rtv on all surfaces of the gasket btw. And just for yucks and grins I roughed up the gasket side of the housing using 800 grit paper.

Then Amazon says they didn’t receive the return and charged me for the product. ID LIKE MY REFUND CANT FIND ANYWHERE TO SOLVE THIS ISSUE. You’re company received monies for no product.
