WHY REPLACE THE THERMOSTAT HOUSING GASKET?
Coolant leaks around the thermostat housing are common on older 12-valve Cummins engines due to gasket shrinkage, age, and repeated heat cycles. Replacing the gasket during thermostat service helps maintain cooling system pressure, prevent coolant loss, and protect against overheating issues.
