Review on πŸš— Mishimoto MMTS-JGC-99L Jeep Grand Cherokee 3.7L/4.7L Racing Thermostat 1999-2010: Performance Upgrade for Optimal Engine Cooling by James Vilchez

Revainrating 5 out of 5

Only after a day or so, but

I can already see the difference in the temperature sensor. Honestly, I hope this lasts as long as the thermostat I pulled out. I'm glad to see that I can actually scream about the difference in the sensors. Now I just hope this will help the motor last longer.

Pros
  • Mishimoto activation: 180Β°F (82Β°C) / OEM activation: 195Β°F (90.5Β°C)
Cons
  • Weight
