colored multi rib belt
The multi-ribbed serpentine belt is usually applicable to alternator, air conditioning compressor, power steering pump, and, sometimes, the water pump and so on.
Driven by the crankshaft, the multi-ribbed serpentine belt powers engine accessories. The serpentine belt is a modern, more efficient replacement for the earlier “V” belt design. The name serpentine describes the path of the flexible belt – it goes over and around multiple pulleys. This belt has its own tensioner and requires regular inspection and maintenance.
