👉 A car's fluid is a critical component that ensures the vehicle operates smoothly and efficiently. It includes various types of liquids, each serving a specific purpose: the engine oil lubricates and cools the engine, preventing wear and tear; the transmission fluid transfers power from the engine to the transmission, enabling gear changes; the brake fluid facilitates the transfer of pressure from the brake pedal to the brake calipers, ensuring effective stopping power; and the power steering fluid reduces the force needed to steer the vehicle by circulating through the power steering pump. Additionally, there are fluids for the alternator, radiator, and windshield washer fluid, all working together to maintain optimal performance and safety.
