🔌 Function

The gasket seals the thermostat cover to the engine cooling passage so water flows through the thermostat instead of leaking around the cover joint.

Common signs of failure:

• Water leaking around the thermostat cover

• Salt or mineral deposits at the gasket joint

• Engine overheating after thermostat service

• Cooling-system pressure loss

• Gasket torn or compressed during cover removal
