What happens to a car when the serpentine belt breaks?
The serpentine belt is also known as an alternator belt, fan belt, or accessory drive belt. If your serpentine belt wears out, becomes damaged or contaminated, or breaks, engine accessories will not be able to spin at the proper speed, leading to decreased power to the electrical system.
What are the symptoms of a broken serpentine belt?
A broken serpentine belt may make a flopping or flapping sound under the hood if it’s frayed or completely breaks away. You may hear tiny frequent ticks under the hood when you accelerate as broken bits of the serpentine belt fly into other components.
What happens if oil gets on the serpentine belt?
The serpentine belt usually drives ancillaries like the alternator, water pump, air conditioning compressor and the power steering pump. Oil on the belt could cause the belt to slip. If it slips while you are turning the steering wheel, then the steering could become difficult to turn due to a loss of power steering.
What causes a serpentine belt to crack?
Excessive cracking is usually caused by old age. Serpentine belts stretch with age and use; as time goes on, the rubber becomes dryer and less pliable making cracking more prevalent. However, cracking can also be caused by a defective tensioner. The tensioner is spring-loaded to keep the belt tight on the pulleys.
There are various symptoms that may indicate your car’s serpentine belt is wearing down, including: Squealing or chirping noises: When the serpentine belt starts slipping, it may begin to chirp or squeal . This sound indicates that there is belt stretch, low belt tension, or the pulley and belt are not working together correctly.
Is it safe to drive with a broken serpentine belt?
Do not drive your car with a broken serpentine belt. Your car will overheat because the serpentine belt drives the water pump (and without a serpentine belt, the water pump doesn’t circulate coolant through the engine and radiator) and it also drives the alternator which keeps the battery charged.
What is the average life span of a serpentine belt?
The lifespan of the serpentine belt will depend mostly on the type of material it’s made of. Older style belts generally last about 50,000 miles, while those made from EPDM can last up to 100,000 miles.
