🔌 Function

The gasket seals beneath the impeller plate so the water pump can develop the suction and pressure required to cool the engine.

Common signs of failure:

• Weak or absent tell-tale stream

• Engine overheats despite a serviceable impeller

• Water or air bypasses beneath the pump plate

• Gasket tears during water-pump disassembly

• Plate will not sit flat because old gasket material remains
