Worked Great
My jeep was running hot and not getting enough air due to the bumper and winch combo. Installed this and it made a huge difference and now it runs much cooler.

2012 Wrangler - MichaelW

Works perfectly
I already had the Mishimoto radiator installed but with a 203 degree thermostat from one if the auto parts store and my jeep would still get a little warm when wheeling. I installed a Mishimoto thermostat a few days ago and it dropped the temperature. My jeep now stays cool and the fan has not been on since. I would recommend this thermostat to everyone with a Jeep Wrangler.

Hit or Miss
Saw some good reviews so I bought in April to replace old thermostat. 6 months later it malfunctioned and stopped sending radiator fluid to my engine.
