Which belt drives multiple engine accessories with a single drive?

Explanation:
A single belt that runs around multiple pulleys to drive several engine accessories is the serpentine belt. It’s a long, continuous belt powered by the crankshaft pulley and routed across multiple accessory pulleys (like the alternator, power steering pump, and AC compressor), with a tensioner keeping it tight. This setup lets one belt do the work for several components at once, which is why it’s described as driving multiple accessories with a single drive. If that belt fails, several systems can go down at once, which is a key reason for its importance. The other options aren’t belts: a coolant pressure cap is part of the cooling system, windshield wipers are driven by a motor and linkage, and indicator lights are electrical indicators.
