🔌 Function

The O-ring seals the upper water-pump housing so cooling water cannot escape around the cartridge or outlet passage.

Common signs of failure:

• Weak tell-tale or cooling-water output

• Engine overheats despite a serviceable impeller

• Water leaks around the pump housing

• O-ring becomes flattened, cut or hardened

• Pump output remains poor after the housing is installed
