Automotive fluids are essential substances used in vehicles to ensure proper operation and maintenance. These fluids include engine oil, transmission fluid, coolant, brake fluid, and power steering fluid. Each type serves a specific purpose, such as lubricating engine components, transferring power, regulating temperature, and enabling safe braking. Regular checks and changes of these fluids are crucial for vehicle performance and longevity. For instance, engine oil helps reduce friction, while coolant prevents overheating. Neglecting fluid maintenance can lead to mechanical failures and costly repairs, making it important for vehicle owners to stay informed about their automotive fluids.
