Drawbacks of the Bad Serpentine Engine

When a belt gets old, the thin channels begin to fade away over time as a result of the constant friction on the belt.
This eventually causes the belt to come loose from the grooves, resulting in the grating sound produced by the engine.
Problems with overheating and battery
The water pump is ineffective as a result of a damaged serpentine belt. It is responsible for the cooling of the engine.
As a result of the problematic belts, the vehicle’s engine gradually loses its ability to perform.
The alternator assists in the battery’s recharge, but a faulty serpentine belt causes the power supply to the battery to be cut off. Battery Obsolete As a result, the battery becomes no longer functional.
Failure Of The Air Conditioning Compressor
The air conditioning compressor is responsible for keeping the atmosphere of the car cool.
The serpentine belt is intimately tied to the compressor, and hence, a faulty serpentine belt can cause a significant degree of malfunction in the air-cooling system.
