How to know if you should change your auxiliary belt and pulley
The auxiliary belt, also known as the serpentine belt or the accessory belt, is a rubber belt that drives various components in your car’s engine, such as the alternator, the power steering pump, the air conditioning compressor, and the water pump. The auxiliary belt is subject to wear and tear over time, and may need to be replaced periodically to ensure optimal performance and avoid breakdowns.
One of the most common signs of a worn or damaged auxiliary belt is a squeaking or squealing noise coming from the engine bay, especially when you start the car or accelerate. This noise is caused by the belt slipping on the pulleys due to insufficient tension or misalignment. If you hear this noise, you should inspect the belt for cracks, chunks, or pilling (rubber material building up in the grooves). These are indications that the belt is nearing the end of its life and should be replaced as soon as possible.
Another sign of a faulty auxiliary belt is the malfunctioning of the belt-driven accessories, such as the power steering, the alternator, the air conditioning, or the cooling system. If you notice that the steering becomes heavy, the battery warning light comes on, the air conditioning stops working, or the engine temperature light comes on, it could mean that the belt is not turning the corresponding components properly. This could lead to serious problems, such as loss of control, battery drain, overheating, or engine damage. Therefore, a mobile mechanic should check the belt for signs of wear or damage, and have replace it if necessary.
In addition to the belt, you should also check the condition of the pulleys, the tensioner, the idler, and the overrunning alternator pulley. These are the components that support the belt and keep it in the right position and tension. They are also subject to wear and tear, and can cause the belt to fail prematurely if they are not functioning properly. Some of the symptoms of a bad or failing pulley or tensioner are grinding or squeaking noises, unusual belt wear, belt vibration, or belt misalignment. If you find any of these problems, you should have the affected component replaced along with the belt.
The auxiliary belt is a vital part of your car’s engine, and you should not ignore any signs of trouble. Replacing the belt and the pulleys is a relatively simple and inexpensive procedure, but it can save you from costly and dangerous consequences. The recommended replacement interval for the auxiliary belt varies depending on the car model, the driving conditions, and the quality of the belt, but it is generally between 40,000 and 100,000 miles. You should consult your owner’s manual or a qualified mechanic for the specific guidelines for your car.
