Engine accessories are components that enhance the performance, efficiency, and functionality of an engine. These can include items like alternators, starters, and water pumps, which help in generating electrical power, starting the engine, and cooling it, respectively. They play a crucial role in ensuring that the engine operates smoothly and reliably. Additionally, engine accessories may also encompass belts, hoses, and filters. Belts transfer power between different engine parts, hoses carry fluids, and filters keep contaminants out of the engine. Together, these accessories contribute to the overall health and longevity of the engine, making them essential for vehicle maintenance.
