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

My Cummins started to heat up and then cool down, I switched to this overpriced thermostat in hopes it would be amazing would have driven on the Autobahn first. I was overheated and didn't want to open. I installed it and it's been working fine ever since. 2 months later and still working perfectly. don't get involved. I put a star because they came back right away, maybe $$
