Mishimoto now offers an alternative to the standard temperature settings of the factory thermostats, Mishimoto low temperature(hot climate) thermostats activate at a lower temperature than the OEM thermostats, making them the perfect solution for Duramax owners who live in warmer climates, or use their trucks under harsh driving conditions. Activating at a lower engine coolant temperature (ECT) means coolant will begin flowing through the system and allow for cooler temperatures. This hot climate thermostat opens at 174/180* vs. OE applications of 180/185*.

The Mishimoto Duramax high temperature(cold climate) thermostats activate at a higher temperature than the OEM thermostats, making them the perfect solution for Duramax owners who live in colder climates, or have trouble reaching operating temperatures. Activating at a higher temperature means the thermostats will allow the coolant to stay in the engine longer delaying the coolant flowing through the radiator, which allows the engine to warm up sooner. This cold climate thermostat opens at 185/191 vs. OE applications of 180/185.
Includes:

• 1 set of Hot or Cold Climate thermostats

DmaxStore Note:

• The oil filler tube and upper coolant pipe seals are not included. They are highly recommended to be replaced during a thermostat replacement to prevent leaks.
