🔌 Function

The gasket closes the joint between the thermostat assembly and cylinder head so cooling water cannot escape or bypass the thermostat.

Common signs of failure:

• Cooling water leaks around the thermostat flange

• Salt deposits form at the cylinder-head joint

• Engine runs too cold because water bypasses

• Engine overheats because the gasket is distorted

• Gasket tears during thermostat removal

• Mating surfaces will not seal after corrosion cleaning
