Squeaking Serpentine Belt

Do the following:

1. Go down to your local parts store and purchase a new serpentine belt and a can of carb cleaner (or brake clean).
2. Take the old belt off and throw it in the garbage. It's useless now that it has a lubricant sprayed on it.
3. Take the carb cleaner and some paper towels and thoroughly clean all of the pulleys where the belt made contact.
4. Install the new belt.
5. Call it a day.
