This is the Reische Performance 170-degree thermostat for 2011 and newer GT, V6, and GT350 Mustangs, and 2012 to 2013 Boss Mustangs. You're gonna wanna check this out if you're looking for a way to keep engine temps cooler, whether you've done some light modifications or tuning, or some more serious mods. Once you start modding, adding more power, and tuning your Mustang, you're then looking at potentially creating more heat. Over time, and depending on how much more heat you're looking at, you can run into a list of problems, from some very minor things, to some more serious things, like engine wear and detonation. A lower temperature thermostat like this one here can protect your engine from those issues and leave you with a more reliable, better-running car. The install for this is gonna be easy. It's a one-out-of-three wrenches on the difficulty meter, and you can plan on spending an hour getting this installed.The thought process here is that keeping your engine cooler has always been a way to get more longevity out of the car, and open the door to more power. Aftermarket thermostats like this one open sooner, which means that the coolant will circle to the rad sooner, which is then gonna keep the engine temperatures lower. And having a cooler running engine has long been known as a way to avoid detonation in super-charged cars, since it keeps the cylinders cooler.One of the nice things about this thermostat is that it's made with an OEM diaphragm and bypass controller. These are two critical parts of the thermostat that need to be fully functional so that this thermostat can work properly. This isn't a universal unit, it's a direct fit, and the OEM parts guarantee maximum efficiency.Now, customers usually ask about re-tuning to deal with the cooler engine temps and fan timing, and this is something that you're gonna wanna consider. And then again, most of you are probably installing this thermostat on cars that are already getting re-tuned due to the mods that you are or have already added, especially if we're talking about a super-charger. Cooler engine temps mean you can have a more aggressive tune with more timing, without detonation or knock, so overall, more performance.When it comes to price, you can expect to pay about $65 for this thermostat. This is currently the only 170-degree thermostat option on the site, and it's the only one made with OEM parts. You do have the option of going with a 160-degree thermostat from Mishimoto if you wanted to spend a little bit less money.As far as the install goes, this is an easy one. It's a one-out-of-three wrenches on the difficulty meter, and you can plan on spending an hour getting this installed. You will need a new bottle of coolant to top off the system once you're done with the install, and of course, either a jack and jack stands or a lift.You'll remove the plastic underbody work, drain the rad, and remove the intake pipe. Once that's out of the way, you'll have room to get to the thermostat housing. Now, that's held in by two bolts, so you're gonna remove those two bolts and remove the stock thermostat. The new thermostat installs exactly the same way. Just be sure to make sure you're using the O-ring and the gasket that comes with the new thermostat because the stock ones won't work properly with the new one. You're gonna reinstall your intake pipe, and you're ready to refill the coolant system, but don't forget to burp the system and get the air bubbles out. After you check for any leaks, you can reinstall the plastic underbody.That's going to wrap things up for the Reische Performance 170-degree thermostat, but you can always check it out more online, right here at americanmuscle.com.
