The engine bay is very important to keeping it maintained and cleaned, allowing dirt and any kicked up debris from the roads to build up in the engine bay can cause wear to external components such as Plastic or Rubber hardware mainly used on Serpentine belts and Vacuum tubes, Electrical harnesses that are exposed as well as Bering’s that are mainly located on any rotating part. Keeping these areas maintained and clean can help avoid any costly damage later on and keep all components functioning and operating smoothly while keeping a clean and sleek look.
