Which component in the lubrication loop is primarily used to cool the lubricating oil?

• A. Strainer
• B. Oil Cooler
• C. LO Header
• D. Pump

Answer: (B)

Keeping lubricating oil at the right temperature is vital for maintaining viscosity and film strength. The component that actually removes heat from the oil is the oil cooler, a heat exchanger that transfers heat from the oil to a cooling medium (often seawater or another coolant). This cooling keeps the oil from thinning too much as it moves past bearings and gears. The strainer removes particulates, the LO header distributes oil, and the pump drives the flow; none of these primarily cool the oil. So the oil cooler is the part that cools the lubrication loop.
