Its been 5 months now. It worked good with my 1995 Ford Explorer XLT 4x4. Highly recommended.

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

No O-Ring provided like the pictures advertised.

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.

Hello wanted to say that this is an excellent product for the original motorcraft or Ford Ranger Ford Explorer 4.0L V6 OHV engine. Comes complete with oring prevents the union lost the pipette body of the thermostat. Comes in its original bag with the part number that matches the manufacturer in the catalog of spare parts. Open to 92 º C temperature as the original factory next. Hola quería comentarles que este es un excelente producto original motorcraft para las Ford Explorer o Ford Ranger con motor 4.0L V6 OHV.

Two stars because even though Amazon clearly states that this thermostat fits my 2000 Ford Explorer XLT with 4.0 V6 SOHC Engine, after paying extra for ordering it with one day shipping because I needed it in a hurry it did not fit my vehicle. This one is actually notably smaller than the original motorcraft that was already installed in my engine, and it falls through the edges that are meant to hold it in place. I am over seas, so its too expensive to ship it back then pay again to recieve the new one. I had to resort to buying a generic thermostat localy :-/ Make sure this part will fit your vehicle even if Amazon says it will fit. The thermostat itself looks good, its original Motorcraft includes a rubber washer and comes in a transparent plastic bag with all sorts los numbers on an attached yellow tag. Too bad it did not fit my vehicle.
