Which action is recommended when the engine shows signs of overheating or abnormal noises?

• A. Increase throttle
• B. Shut down the engine
• C. Ignore and continue
• D. Reduce speed but keep running

Answer: (B)

When you notice overheating or unusual engine noises, the priority is to stop the engine to prevent serious damage. Shutting down as soon as it’s safe to do so reduces heat buildup and stops components from continuing to operate under potentially failing conditions. After safely pulling over, let the engine cool, then inspect for leaks and check coolant and oil levels, and arrange for service as needed. Raising the throttle, continuing to run at a reduced speed, or ignoring the problem would all let the issue worsen, risking severe damage to parts like the head gasket, cylinders, or bearings.
