LMM/LML Duramax Diesel

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*.

Includes:

• 1 set of Hot 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.
