Motorcraft 180 Degree Thermostat Assembly 2014-2019 Fiesta ST

$ 59.27

Keeping your Fiesta ST's coolant temps under control is easy with the Ford Motorcraft 180 Degree thermostat.

This Fiesta ST thermostat activates at 180°F vs. the stock 207°F allowing the coolant to flow through the engine earlier.

If you are sitting in bumper to bumper traffic on hot summer days or at the track heating things up, adding this lower temperature thermostat will be the answer in keeping engine temps down.

While installing the lower temp thermostat, it's a great time to upgrade your radiator hoses. whoosh brand silicone kits can be found HERE

Great choice with radiator upgrade

I chose this over the Mishimoto 160° and I am very happy with it. I installed this when I replaced my radiator with a Mountune radiator. I haven’t seen a temperature above 206° yet and that’s on a warm humid day with the A/C on and driving aggressively on mountain roads. I like that the engine is not too cold and should provide adequate heat in the winter. Quality was Very good. Not the easiest install but a confident mechanic should be able to handle this job easily.
