Mishimoto Low-Temperature Thermostat - 01-16 GM Duramax 6.6L

The Mishimoto Chevrolet Duramax low temperature 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 heavy load or strenuous driving conditions. Activating at a lower temperature means coolant will begin flowing through the system and allow for cooler temperatures.
