Review on ๐ŸŒก๏ธ Mishimoto MMTS-CHV-01DH High-Temperature Racing Thermostat for Chevrolet GMC 6.6L Duramax (2001-2016) by Robert Grimm

Revainrating 5 out of 5

Perfect for cold weather

They fit perfectly and work just as well as thermostats. I put these on high temp because of our cold winters, my truck had a real problem getting so warm my window wouldn't dew. I definitely noticed a difference, the truck heats up just as quickly as before but gets hotter and stays hot so my glass stays thawed. Have used it for 9 months now no problems at all.

Pros
  • Stylish and modern design
Cons
  • Outdoor
