Good To Know
Q: Why does the Duramax engine use two different temperature thermostats? A: The dual-thermostat system allows progressive coolant flow. The 180-degree thermostat opens first for light cooling needs, while the 185-degree thermostat opens under heavy loads to maximize coolant circulation through the radiator.
Q: Should I replace both thermostats at the same time? A: Yes, it is highly recommended to replace both thermostats as a pair to maintain balanced cooling performance and prevent thermal shock in the engine block.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
