Review on ๐Ÿš— Mishimoto MMTS-JGC-99L Jeep Grand Cherokee 3.7L/4.7L Racing Thermostat 1999-2010: Performance Upgrade for Optimal Engine Cooling by Tyrazz Abouzar

Revainrating 1 out of 5

Too expensive and doesn't work as expected in my case.

It was expensive. And my coolant temp was still over 200ยฐF. I was expecting the reading to be much lower. I went back to the OEM temperature thermostat. The temperature is still around 200ยฐF, but at least it should be. I replaced the coolant temp sensor and flushed the entire cooling system to get the correct temp reading.

Pros
  • Keeps temperatures cooler and extends engine life
Cons
  • I don't really like it, everything is fine
