From daily drivers to modified vehicles, The 6.6L Mishimoto Chevrolet Duramax high-temperature thermostats are a surefire way to have your Chevy/GMC's engine operating efficiently, especially for drivers who live in colder environments. Precision designed and manufactured, the Mishimoto high-temperature thermostat uses a high-quality wax and new rubber gaskets that are deliberately calibrated for precise operation. When warming up your engine, the thermostat effectively opens up at a slightly lower operating temperature than your OEM thermostat. In effect, this allows a steady flow of coolant to flow through your vehicle's engine sooner, keeping your engine optimally cool through any and all environments and applications.
