yes the serpentine belt will be hot after running engine
If it has a serpentine belt it should have an automatic belt tensioner If it doesn't have a serpentine belt then alternator should be the adjustment/pivot point
Look at the ribs on the inside of the belt, if they are cracked or missing small chunks then replace as soon as possible. I usually replace mine every 2 - 3 years.
The alternator, water pump, power steering pump, air conditioner and possibly the air pump receive power from the serpentine belt.
