If the serpentine belt becomes worn, damaged, or misaligned, it can cause friction and generate smoke.

Is my serpentine belt too tight?

If your serpentine belt is causing issues like excessive noise or accelerated wear on the pulleys, it may indicate that the belt is too tight.

Why did my serpentine belt come off?

Serpentine belts can come off due to factors such as belt wear, improper tension, misaligned pulleys, or a faulty tensioner.
