🔌 Function

The cooler transfers heat from lubricating oil into the raw-water circuit. Controlling oil temperature preserves viscosity, bearing protection and stable oil pressure during sustained load.

Common signs of failure:

• Lubricating-oil temperature rising above normal

• Low oil pressure after the engine reaches operating temperature

• Oil film in the raw-water discharge or coolant circuit

• Water-contaminated or milky lubricating oil

• External leakage, corrosion or failed pressure test

📦 Condition
