The Serpentine Belt transfers power from the engine to most of your major engine components: alternator, water pump, power steering pump and air conditioner compressor. Over time, the rubber belt will become brittle and crack. If the belt breaks, you will be left stranded. It’s important to have your belts checked regularly.
NOTE: A new serpentine belt eliminates possible damage to your engine caused from driving after the belt fails. It also prevents you from being stranded and eliminates that annoying chirping sound from a glazed belt.
