What is the quantity of oil included in a typical serpentine belt service?

In a typical serpentine belt service, the quantity of oil involved is actually not directly related to the number of belts, as serpentine belts are components that drive multiple accessories in the engine. The key factor in this service is the installation of one serpentine belt, which is designed to operate various engine accessories, such as the alternator, power steering pump, and air conditioning compressor.

When performing a serpentine belt service, technicians focus on the inspection, replacement, or adjustment of a single belt, making sure it functions properly. Other components may be checked, but the primary service is centered on that one belt. Therefore, the correct answer reflects that only one belt is included in a typical serpentine belt service.
