* Most likely, it has a serpentine belt. This single belt drives the alternator, power steering pump, air conditioning compressor, and water pump.
* Some configurations *might* also have a separate belt for the air conditioning compressor. This is less common in the 2002 Malibu, but it's possible depending on options and specific engine.
To know for sure, you need to:
1. Check your owner's manual: This is the best source of information specific to your Malibu's engine.
2. Look under the hood: Carefully inspect the engine compartment. You should clearly see the belt(s). A serpentine belt is a single long belt that loops around several pulleys.
Don't attempt to work on the belts yourself unless you have experience. Improper handling can lead to injury.
