Review on Mishimoto Low-Temperature Racing Thermostat (MMTS-RAM-99L) - Compatible with Dodge Cummins 5.9L & 6.7L (1999-2013) by Todd Worley

Revainrating 3 out of 5

01 Cummins 24v Diesel Engine

It did an excellent job on my Cummins keeping temperatures between 175-195 and towing 28,000 pounds. Worst of all, the spring and bottom washer fell off after 4,000 miles. Much better than Gates T-Stat when lifting weight.

Pros
  • Ideal for vehicles in warm climates or extreme towing/driving conditions
Cons
  • Negative Present
