🔍 Key Concepts

• Raw (sea) water cooling system purpose in a diesel engine • Relationship between cooling water flow and jacket water temperature • What typically happens to lubricating oil viscosity when temperature changes

💭 Think About

• Think about what happens to engine metal parts and enclosed water passages if cooling flow is blocked but the engine keeps running under load. • Consider how temperature affects viscosity: when oil gets hotter, does it become thicker or thinner? • Ask yourself which of the options describes a direct and immediate result of losing raw water flow, not a rare or long‑term side effect.

✅ Before You Answer

• Identify which component of the engine is directly cooled, and how a loss of raw water flow would show up on engine temperature gauges. • Verify in your notes how jacket water temperature normally behaves if cooling is reduced or stopped. • Double‑check your understanding of how oil viscosity vs. temperature works before choosing any option mentioning lube oil.
