What should you do if you see an abnormal continuous thick white cloud coming from the exhaust?

• A. Increase throttle
• B. Open the radiator
• C. Refill fuel
• D. Shut down the engine

Answer: (D)

White smoke from the exhaust indicates something abnormal getting into the combustion process, most commonly coolant leaking into the engine or an overheating condition. This signals a serious engine problem that can quickly cause major damage if the engine keeps running. The safest move is to shut the engine down to stop any further damage and allow it to cool. After safely stopping, check for coolant loss or leaks and arrange service. Do not open the radiator cap while it’s hot, and avoid revving or forcing the engine. Increasing throttle would just add heat, refilling fuel won’t address a cooling issue, and opening the radiator while hot is hazardous.
