MishimotoMMTS-MUS8-11 Low Temperature Racing Thermostat, Compatible with Ford Mustang V6 & V8, 2011-2018

great product bought my mustang sep 2021 in st. louis drove it home to detroit. it's FBO and immediately my car had been running warm cylinder heads around 225-235 with heat blasting. took it to a shop a few times told everything was fine. about 4 months later my radiator cracked was told my tstat was fine got a new radiator, gut feeling it was my tstat the whole time met a friend through a friend ordered a new tstat replaced it today now car runs at 180-185 no heat blasting coolant around 175 saw the oring issues bought a extra incase had no issues with the one they gave. would reccomend 100% should've trusted my gut earlier would've saved me 800 bucks for another performance radiator lol. if you are concerned about the oring buy a extra it was 8 bucks. tstat works great car is running 40-50 degrees cooler

Worked perfectly on my 2015 f150 5.0. My stock replacement thermostat worked but the fans were always on high cool even in the winter. The best is that the temp display doesn't have 235° above it anymore. O-ring gasket didn't work but I already knit from other reviews. Thanks so much

At first I was skeptical because of the price but decided to buy it anyway. I have a 2013 ford f150 3.5l ecoboost and my cooling fans would run on high constantly. Which are extremely loud and pretty embarrassing at times. So going down the list of possible remedies i gave this lower temp thermostat a shot. With Oem thermostat it would get up to around 215-220. With the mishimoto thermostat installed it hasn't gone above 190 even when towing. So its does what it's supposed to do..but that didn't fix my problem with the fans.... just an FYI for anyone else with this issue it Turns out my ac system was over pressurized and thats what was causing the fans to run on high all the time.

2016 F150 received P0128 error code and check engine light will illuminate. Wouldn't care about light, but this also makes your remote start unusable. Wasted $60 bucks as I threw box away and can't return the item. O-ring was also incorrect size. Replace with an OEM instead.

This thermostat solved my problem. Not because it's a 160 degree. Found out 2 types of thermostats. Hot face and cold face thermostat. If you use a hot face tried 3 before learning in truck overheated with all three.I stalled this cold face thermostat solved it.

It’s advertised as a 160 degree, bought it for my 2019 roush f150, coolant temps stay at around 170-175, would go a different brand next time

Install is very simple and immediately decrease CHT temps but a lot. My car stays under 188CHT during normal driving.

The media could not be loaded. The thermostat itself is ok but come on guys look at this Oring do you think this is right? lol
