Ratstat 170 Performance Thermostat - 4D V2

Fits the following:
  • 2015-2017 F150 EcoBoost 3.5L

Ratstat 170-degree thermostats will give you the low coolant temperatures and heat dissipation needed to get the most out of your Ford vehicle. Aftermarket radiator or not, this thermostat will help get your Ford to the temperature it needs to be at. No more long waits for your vehicle to warm up or decreased performance in colder environments like you would get with lesser thermostats. Maintaining the balance between a productive level of performance and high flow to the radiator is important for high performance vehicles. A 170-degree opening temperature is how to reach that balance. All it takes is your fan to be properly set. With that, your temperatures in cooler weather will be in the 170's, while just taking it easy down the road. In the 180's, on those hotter days. Vehicles with extra boost or using advanced levels of timing need this to help defend against detonation, while still getting the highest levels of performance possible. Plus, these thermostats come with a 2-year warranty.

NOTE: This 170-degree thermostat is a different size and designed differently than the OEM thermostat. This is due to a different gasket being used in the construction of the thermostat. You must use the O-Ring from the stock unit and place it around the thermostat to fit Ford's new plastic thermostat housing.


To fully take advantage of this upgrade the PCM/ECU will need to be calibrated with an MPT tune. If you already have an MPT Tune, simply submit a new MPT Tune Form telling us what you have installed and your invoice number for the thermostat purchase. Please allow three business days for tunes to be built/updated.

Easy Install
If you have a 2019 Raptor, this thermostat is super easy to install. Ford moved the thermostat housing (Model year?) and you don't have to remove any air intake or additional items as seen in some installation videos. Truck runs much cooler in Hot as hell Houston TX

This did awesome
I ordered the 170° thermostat to help with some higher temperatures on my newly built 3.5 It arrived a lot sooner than I expected, especially with this COVID-19 thing going around. The guys MPT were great in assisting me, and the thermostat has lowered my temperatures in my built 3.5 from running in the 210 to 218 range down to 175 to 190. I couldn’t be happier with this product and the service that I received, and it did exactly what I wanted it to do. I’d highly recommend buying this from the guys at MPT if you would like your eco-boost to run cooler. Thanks Guys.
