🔍 Key Concepts

• Thermostat function in a diesel engine cooling system • How heat exchangers affect jacket water temperature • Typical effects of air in a cooling system vs leaks or cracks

💭 Think About

• Which problem would more likely cause jacket water temperature to rise instead of fall? • What happens to coolant flow and engine temperature if a thermostat sticks open compared to sticking closed? • Would a cracked water-cooled exhaust manifold remove heat from the jacket water or introduce additional heat into it?

✅ Before You Answer

• Determine which fault would increase engine temperature and eliminate those choices. • Think about whether a blockage in the heat exchanger makes the engine run hotter or cooler. • Recall whether air binding usually causes loss of circulation and higher or lower temperatures at the engine.
