Your cart is empty.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.

These barely lasted a year. I don't drive my truck very much mostly to haul my camp trailer. I think these have been the cause of my over heating problems I've had everytime I haul my trailer. And now they have completely failed I tested them in boiling water and neither of them open even when the temp is 200degs. I wouldn't buy these again!

I didn't pay attention at first and got warm thermostat and thought my truck had a overheating problem, but looked at what I bought and switched them for the colder ones and it set everything back straight .

Good product. Lowered operating temp from 210 to about 170 in my 05 Duramax. Worth the investment for an LLY known for its overheat problems.

I installed this on my Duramax LBZ and found that the thermostats being to open at the same temperature as specified, checking with the reading on my Edge CTS2 and an infrared thermometer on the housing and inflow/outflow hoses. Seems to be of good quality and reliable so far.
