  • Did not come with rubber seal ring.
Motorcraft is the best for ford O.E. No arguments there, but be advised this did not come with seal ring as pictured. Did not notice until I started project and return date has passed. Now off to Vato-zone for a silly rubber ring that may or may not be compatible. Definitely get motor craft for ford oe. Don’t forget to check package like I did. ... show more

  • Fits and Works as it should.
Its been 5 months now. It worked good with my 1995 Ford Explorer XLT 4x4. Highly recommended.

  • Does not include necessary gasket for installation
Kinda useless without the gasket THAT IS PICTURED WITH THE THERMOSTAT. This is absolutely top dollar for this part, and cannot be installed without another visit to the parts store. Will be returning and trusting the brick and mortar parts store. Very disappointed.

  • Perfect Fit
Perfect fit for my 1995 Ranger. Solved the problem of not getting up to proper operating temperature.

  • Fits 1996 Ford Explorer 4.0L V6.
I installed the thermostat in a 1996 Ford Explorer 4.0L. My OBD reader reports 195F to 205F degrees while driving and the analog dashboard gauge is slightly below 1/2 scale. Although hotter than the description's rating, it's an acceptable temperature range for this vehicle. For reference, the previous thermostat was the same part number but operated at 180F under all load conditions. A lower temperature is less desirable than the warmer temperature range seen with the new replacement. The thermostat includes the rubber O-Ring gasket. I suggest applying a thin layer of automotive type High-Temp RTV silicone (gasket maker) on the inlet housing's mating surface. ... show more
