Review on 🏎️ Mishimoto MMTS-RAM-99H High-Temperature Racing Thermostat for Dodge 5.9L 6.7L Cummins 1999-2013: Boost Performance and Reliability! by Enes Patiag

Revainrating 1 out of 5

My engine is overheating

Fit 2007.5 6.7 cummins. Easy installation. Terrible design. It failed on a long drive and the coolant temperature rose to 240 degrees. A complete waste of money. The engine is not worth the risk of this Chinese thermostat. Buy OEM. The "C" clip will come loose and the spring behind it can become loose and possibly get stuck in your cooling system or water pump.

Pros
  • Thermostats
Cons
  • Doubtful purchase for the elderly
