4 Signs of a Failing Serpentine Belt

A serpentine belt, also known as a drive belt, is a crucial engine component. It is responsible for driving various engine accessories such as the alternator, power steering pump, and air conditioning compressor. If the serpentine belt fails, it can cause a range of problems for your vehicle and interrupt your daily schedule. Keep reading to discover a few signs of a failing serpentine belt.

1. Squealing Noise

A loud squealing noise is one of the most common signs of a failing serpentine belt. This noise is typically caused by the belt slipping on the pulleys. If you notice the squealing noise when the engine is started or when the car is accelerating, visit a professional mechanic near you to diagnose and repair the issue

2. Power Steering and AC Not Working

If the serpentine belt is not functioning properly, it can prevent the power steering pump and air conditioning compressor from operating. This fault can make steering more difficult and make it impossible to use the air conditioning.

3. Engine Overheating

The serpentine belt is also responsible for driving the water pump, which is responsible for circulating coolant throughout the engine. If the belt fails, the water pump may not function properly, which can cause the engine to overheat.

4. Cracks and Wear On the Belt

A visual inspection of the serpentine belt can also reveal problems. If you see cracks or significant wear on the belt, it may be time to have the belt replaced.
