Review & Install Video

Protect that Power. If you're adding some bolt-on performance to your mustang, you're adding more heat and power loads. The Reische Performance Thermostat operates at 170 degrees compared to the 180 to 195 degrees of your OEM unit, which allows your motor to run cooler, longer, under higher output. Installing this thermostat is a simple but critical investment in protecting your engine.

Tune it? Cool it. If you're advancing timing on your motor or operating a custom tune, a lower temperature thermostat is a critical investment in engine life. Lower temperatures allow for safer timing advancement and tuning without causing engine wear or detonation, which can ruin your motor.

Made to Fit Mustangs. Unlike cheaper, generic units that are "universal", each Reische Performance Thermostat is made using the same diaphragm and bypass control as OEM thermostats. Each unit is modified by hand with U.S made parts to ensure they run at the right temperature for your Mustang.

All-Weather Capable. Running a lower temperature thermostat has been said to reduce performance – but with the Reische's consistent operation and 170-degree "sweet spot", no drivers have reported any loss of power or MPGs in colder weather.

Application. The 170-Degree Reische Performance Thermostat is specifically designed as a direct replacement-upgrade for all 2011-2017 GT, V6, GT350, and '12-'13 BOSS Mustangs.

Tuning Note. While no tuning is required for installation, we do highly recommend lowering your fan settings for more consistent coolant temperatures.

If I already have a map installed on my ECU with my handheld tuner, all I need to do is drop this in correct?

  • The Reische Performance Thermostat - 170 Degree does not require a tune, however we strongly recommend a tune to accommodate for the lower opening temperature of this thermostat. Any tune you have now would not have this accommodated for unless you specified this with your tuner.

I have heard complaints that the engine fans don't turn once this part is installed. I am considering buying this along with the Bama x4 tuner. Will the handheld tuner be able to adjust the engine fans or will I have to do that elsewhere?

ZacT

  • The Reische Performance Thermostat will lower the temperature at which the thermostat opens by approximately 25 degrees, reducing the frequency of the electric cooling fans being commanded on due to lower coolant temperatures and not reaching their on point as often. Cooling fans on/of temps can be adjusted with a tuner, but it is not often recommended as this can push the car into running at temps that are not good for performance.

Will I need a tune after this? If not, will my check engine light come on? Thanks.

  • Tuning the motor after installing a lower temperature thermostat is critical to guarantee proper internal temperatures. If you do not tune the vehicle after installing the thermostat, you can expect premature wear of the motor and possible detonation.

  • If you’re advancing timing on your motor or operating a custom tune, a lower temperature thermostat is a critical investment in engine life. Installing this thermostat without loading a new tune can wear the motor or potentially lead to engine detonation.

  • You should not need to make any adjustments in order to have a proper installation of the Reische Performance Thermostat. It is designed to be a direct replacement.

    It actually helps alot

    Before switching this thermostat into my v6, it would run with cylinder temps of 196 with constant spikes to 212 and the rare spike of 235. Since installing ive only gotten to 196 when leaving the car running while not moving after a trip, but while moving it ranges from 174 to 183. Much healthier and actually helps MPG on dailly driving and oil temps while pushing it hard. All in all the peace of mind is definitely worth it! P.S. If there is a loud hissing/screaching its just the air getting out of the system, just squeeze the hoses as its running

    Definitely cooler!

    Could really tell the difference from the 170 on a supercharged 2014. I started to notice that my car would sit higher in the 209ish temp. With this thermostat I now will sit at 199 cylinder head for much longer. As long as I am not driving on a very long highway trip at 80mph this thermostat keeps it cooler. Once I compliment it with a larger radiator I'm sure I will have an extended benefit!

    Seems to lower temps

    I was skeptical about this thermostat, but was having oil pump gears installed and since the stock thermostat had to be removed anyways, i decided to replace it with the reiche 170 degree. Since it's been installed cylinder head temps generally stay at or below 200 degrees. Before with the stock t-stat temps were more in the 210-215 degrees range when fully warmed up. Also make sure you have your tuner adjust your fan settings to take full advantage of the lower temp stat. I have a lund tune and they already account for the lower temp t-stat.

    Beat the Heat!

    Installation took an hour with the vast majority of the time being lifting the car and removing all the lower service panels. Make sure you really drain the coolant system or this will be very messy. After the installation and re-tune my heavily modded N/A build ran 15 degrees cooler than before. Team this with Mishimoto Liquid Chill to run 25-30 degrees cooler! My engine runs much smoother and my exhaust note slightly changed aswell. I highly recommend doing this thermostat if you have moderately or heavily modded your GT. Remember that a tune from your tune specialists is absolutely required for this thermostat to work.
