1. Engine Oil: Engine oil is a lubricant that reduces friction between moving parts of the engine and helps dissipate heat. It is stored in the oil pan and circulated throughout the engine by an oil pump.
2. Coolant (Antifreeze): Coolant, also known as antifreeze, is a mixture of water and antifreeze chemicals. It circulates through the engine and radiator, absorbing heat from the engine and transferring it to the radiator where it dissipates into the atmosphere.
3. Brake Fluid: Brake fluid is a hydraulic fluid used in the car's braking system. It transmits the force from the brake master cylinder to the brake calipers or wheel cylinders, which in turn apply pressure to the brake pads or shoes to slow down or stop the car.
4. Transmission Fluid: Transmission fluid is a lubricant and hydraulic fluid used in automatic and semi-automatic transmissions. It helps in smooth gear shifting and transfers power from the engine to the wheels.
5. Power Steering Fluid: Power steering fluid is used in vehicles equipped with power steering. It assists the driver in turning the steering wheel by reducing the effort required.
6. Windshield Washer Fluid: Windshield washer fluid is used to clean the windshield and remove dirt, dust, and other debris. It is sprayed onto the windshield through nozzles and wiped away by the windshield wiper blades.
7. Fuel: Gasoline or diesel fuel is used to power the car's engine by burning in the combustion chambers.
8. Hydraulic Fluid: Hydraulic fluid may be used in various systems such as the power convertible top, power seats, or suspension systems, providing power and movement.
Regular maintenance and checks are essential to ensure that these fluids are at their optimal levels and condition for the proper functioning of the vehicle.
