Yes, a serpentine belt can cause smoke. A serpentine belt is an essential component of a vehicle's engine system. It drives various accessories such as the alternator, power steering pump, water pump, and air conditioning compressor. If the serpentine belt becomes worn, damaged, or misaligned, it can cause friction and generate smoke.

The serpentine belt can squeal due to various reasons, including tension issues, worn-out belt, or a problem with the belt's pulleys.

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.

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