If the water level dropped rapidly in the expansion tank of a closed diesel engine cooling water system, you should suspect a __________.

🔍 Key Concepts

• Closed cooling water system operation and the role of the expansion tank • How a leak between fresh water and raw (sea) water would affect system levels • Differences between problems on the freshwater side vs the raw water side of the cooling system

💭 Think About

• Which component or fault could actually remove cooling water from the closed system quickly, causing the expansion tank level to fall? • For each choice, decide: Does this fault change the amount of water in the closed system, or only its movement/temperature? • Think about where the closed cooling water can physically escape to if there is a failure in a heat exchanger or pump.

✅ Before You Answer

• Identify which options affect circulation only versus actual fluid loss • Consider where the freshwater and raw water circuits meet in a typical marine diesel cooling system • Ask: In which fault would the expansion tank level drop rapidly, not slowly or not at all?
