Here's why:
* Engine overheating: Water is not a coolant. Putting it under the bonnet can lead to steam build-up, potentially damaging the engine.
* Electrical components: Many electrical components are located under the bonnet, and water can cause short circuits or damage.
* Corrosion: Water can cause rust and corrosion on metal parts.
If your car is overheating:
* Pull over to a safe location: Turn off the engine and allow it to cool down.
* Check the coolant levels: Do not open the radiator cap if the engine is hot. Look for the coolant reservoir and check the level.
* Add coolant if needed: Use the correct type of coolant (refer to your owner's manual) and only add it to the coolant reservoir.
* Call a mechanic: If you're not comfortable with checking the coolant or if the engine is overheating consistently, contact a qualified mechanic.
Always be cautious when working with car fluids and never pour water under the bonnet. Consult your owner's manual or a mechanic for specific instructions and guidance.
