The alternator, power steering pump, water pump, and air-conditioning compressor may all be connected to this serpentine belt.

Why does my serpentine belt slip in the morning?
Very small amounts of water appear on the serpentine belt in the morning acting as sort of lubricant, causing the belt to slip. This, combined with the beginning of belt material fatigue will cause this sound. It usually disappears once the belt warms up a bit (like 10 to 20 seconds after the engine is started).
How do you change a serpentine car belt?
If you can find some instructions on how to change the belt they should tell you how tight it should be, but if you can depress it more than half an inch with your fingers (when the engine is off, of course!!!) it’s probably too loose. Loosen both bolts, then push the alternator as hard as you can to tension the belt while you tighten the top bolt.
