If you are wondering what a serpentine belt is, then you have come to the right spot. This mechanism is a long, winding cincture that ties the air conditioning system, alternator, water pump, and power steering pump together. In other words, it keeps them running in perfect harmony. Built to last a very long time, you should have to change yours out until somewhere between 60,000 and 100,000 miles. Thanks to advancements in rubber technology, the new parts are more durable than ever before. However, if yours is manually tensioned, it may need to be adjusted. Most come with a self-tensioning device, but that also might need servicing at some point due to wear and tear. One thing to keep in mind, the vehicle will not run if the belt breaks. While the serpentine belt wears many hats, it can fray, crack, peel, or even become glazed at any point. The following are signs of a belt that need replacing. Chipping or squealing - These unusual sounds happen when the serpentine belt slips out of place, has low tension, or is contaminated by antifreeze or an oil leak. Poor performance - If the battery suddenly drains or your power steering stops working, then your belt is compromised. This may also lead to damage to the alternator, water, air conditioning, and other components. Contact Ford Parts BC to learn more!
