🔌 Function

The O-ring seals the clearance between two mating components. Depending on its installation, it prevents cooling-water leakage, gear-lubricant leakage, oil leakage or water entry.

Common signs of failure:

• Water leaking around a thermostat cover

• Milky or contaminated gear lubricant

• Oil seepage around the installed fitting

• O-ring hardened, flattened or cracked

• Engine overheats after thermostat service

• Gearcase fails pressure or vacuum testing
