🔌 Function

In water-pump applications, the O-ring seals the lower base to maintain cooling-water pressure. In intake applications, it prevents unmetered air from entering around the carburettor or air-silencer joint.

Common signs of failure:

• Cooling-water pressure becomes weak

• Water leaks around the pump base

• Engine develops a lean or unstable idle

• O-ring becomes flattened, cracked or fuel-soaked

• Sealing problems begin after pump or carburettor servicing
