🔍 Key Concepts

• engine jacket (cooling) water system and heat removal • effects of lubrication or mechanical failure on temperature • how fuel quality or filters affect combustion vs. cooling

💭 Think About

• Ask which option directly reduces the effectiveness of heat removal from the engine metal surfaces. • Consider which choices would mainly affect combustion efficiency rather than the cooling system itself. • Think about what would happen to jacket water flow, temperature, and engine metal temperatures if each choice occurred.

✅ Before You Answer

• Identify which option would most logically cause more heat to be transferred into the jacket water or less heat to be removed. • Eliminate options that mainly affect fuel delivery or combustion quality without immediately overheating the cooling water. • Decide whether higher water level in the expansion tank would raise or lower the risk of overheating, based on how the system works.
