Mechanics - Vehicles - What to know under the bonnet

Brake fluid

Transmits the braking force to the four wheels of the car when you press the brake pedal. It flows through the braking system. Located on the pedal side, under the bonnet on the right. Opening is prohibited as this fluid attracts moisture and damages the braking circuit.

Engine oil

Serves to protect against corrosion, cool the engine, clean the engine, lubricate engine parts and prevent friction between engine components.

The oil dipstick

Used to check the oil level. A vehicle's oil level must be checked regularly, approximately every 1,500 km, and particularly before a long journey. Check on level ground with a cold engine. The risks of driving with an inappropriate oil level are significant: breakdown, engine failure, etc.

Coolant

Maintains a constant engine temperature. Prevents overheating and water freezing. Limits the risks of oxidation and limescale deposits in the circuit.

Windscreen washer fluid

Used to clean the car windows. Ensures good road visibility for the driver and therefore maximum safety.

The battery

Component located under the vehicle's bonnet.

Knowing the main components under your vehicle's bonnet is essential to ensure its longevity and your safety on the road. Regular checks of engine oil, brake fluid, coolant, washer fluid and the battery will allow you to anticipate problems and avoid costly breakdowns. Remember that these simple checks can make all the difference between a peaceful journey and a roadside emergency. Take care of your vehicle, and it will take care of you.
