What happens if your car overheats and you keep driving?
If you continue to drive an overheated car, you run the risk of warping your cylinder heads. This result is decreased power, misfiring, and excessive oil burning. However, cylinder heads aren't the only things in your engine that can melt; other components like sensors, belts, and wiring are also at risk.
Can I pour water on my engine to cool it down?
If your engine is still hot, don't pour cold water on it. Pouring cold water on a hot engine can cause serious damage. Instead, let the engine cool down on its own or use a coolant to help speed up the process.
