Fits/works
Fits well, works well. Despite being Motorcraft brand, there is an “S” imprinted on it. I’m assuming Stant is making these for Ford now but I don’t know. In any case, it fits and works as it should.

Works great! Good quality
This thermostat is made of good quality materials and works great. I didn't like the idea that it doesn't come with a gasket but had to be ordered separately. I do feel it is a good replacement for the original thermostat.

I have heat again!
I bought an off brand and it never worked. I just popped in this motorcraft thermostat and the vents are finally blowing warm air. The needle stays right in the middle. I’m very happy

OEM
I flushed the entire system, added new coolant to specifications. Worked perfect for a couple weeks, now it’s starting to get hotter before it opens. Not sure what’s going on.
