Beginning with the malfunctioning air conditioner, overheating issues, and the battery losing its power faster.
The easy way to find this problem is to check if there is any crack on the belt or not. If there are any cracks and the belt is worn off, then you must change the belt.
Loose serpentine belt:
A serpentine belt is mainly made of rubber. That gives the stretchy texture to the belt to work simultaneously throughout the engine without causing the problem. As time goes by, the flexible state of the belt starts to fade.
As time goes on, the serpentine belt becomes loose, creating a problem. The problem includes malfunction in the power steering system, check engine light, screechy sound from the engine, and draining of battery power.
How to tell if the serpentine belt is bad?

Properly Aligned with The Pulleys:
There are some grooves over the serpentine belt, which helps to stay put with the pulleys. So, if the belt stays good, it will remain attached to the pulleys. But if the belt misplaces anyhow, the engine will not work correctly.
Look if the belts are Slippery:
Slippery belts will not have grip. That will cause the problem of displacement all the time. So, just look for the belt that has a proper grip.

When the belt becomes old, the thin channels start to fade away over time due to constant friction. That ultimately turns the belt to lose from the grooves and creates the engine’s lousy sound.
Due to a bad serpentine belt, the water pump works ineffectively. The water pump plays the role of engine cooling. Gradually the overheating issues cause the vehicle to lose the competence of the engine.
As the alternator helps the battery recharge, a bad serpentine belt aborts the power supply to the battery. That results in the battery to obsolete.
Malfunction in Air Conditioning:
The air conditioning compressor helps the atmosphere of the vehicle to stay cool. As the serpentine belt is directly related to that compressor, a bad belt can create a vast amount of malfunction in the air-cooling system.
Why did my check engine light turn on after changing the serpentine belt?
