Good To Know
Q: Why replace both front and rear thermostats at the same time? A: The Duramax 6.6L uses two thermostats working together; replacing only one can lead to uneven cooling and early failure of the other.
Q: Will this thermostat kit work with my stock cooling system? A: Yes, it is designed as a direct replacement for the original thermostats in the Duramax 6.6L cooling system with no modifications needed.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
