The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and, in some cases, your water pump running smoothly and effectively. Without this belt, the battery will not get charged and none of the electrical accessory components in the car will work.

Typically comprised of rubber and guided by hydraulic (or spring-loaded) belt tensioners or idler pulleys, serpentine belts connect your alternator, water pump, power steering system AND air conditioning unit to your crankshaft and transfer power from your engine to these vital components.

Since these belts perform such an important task, having them inspected and changed out regularly is extremely important to your vehicle’s health. If they wear out and snap from constantly being exposed to the intense heat produced by your engine, your engine can shut down completely and cost you a lot of money in repairs to the various systems supported by serpentine belts.

Signs your serpentine belt needs to be replaced include loss of power, noticeable vibrations, audible squealing and steering difficulties. Loud Drive Belt– If there is a noisy squealing coming from the serpentine belt then it is important that you have your vehicle inspected immediately. If the issue is being caused by leaking or spilled motor oil though, it can mean a complete replacement is needed for the belts and it will need to be replaced immediately before any more damages can be caused.
