What is a serpentine belt and how does it work?

A serpentine belt is a relatively long, flat, multi-ribbed belt that is driven by the engine'southward crankshaft pulley. The belt drives many, and often all, of the engine accessories such as the alternator, air conditioning compressor, power steering pump, water pump, and air pump. The serpentine belt is tensioned past a hydraulic or leap-loaded automated tensioner. Some older cars employ a serpentine belt to bulldoze nearly accessories but will likewise have a shorter five-way belt to bulldoze, for case, the power steering pump.

Belts

When to consider replacing the serpentine belt:

Regularly scheduled maintenance. Typically, chugalug manufacturers recommend belt replacement at 90,000 miles. However, the chugalug must be inspected for wear or damage at regular intervals prior to this high mileage.
Squealing racket, belt slippage, visible chugalug damage. Should the belt fail or wear out prematurely, you may hear noise or y'all may run across visible signs of deterioration such every bit missing chunks of rubber, excessive corking, or a shredded appearance on the edge of the belt.
Battery Light. A loose chugalug, perhaps acquired by a defective tensioner, may not drive the alternator at adequate speed and thus the bombardment may discharge, causing the warning lite to illuminate.
Engine overheating. Often, the serpentine belt drives the water pump. In those applications, if the belt breaks the engine volition overheat in seconds to minutes. If the belt is inadequately tensioned, you may notice higher-than-normal engine operating temperature.

How do mechanics supercede the serpentine belt?

Prior to removing the belt, the mechanic must run the engine to decide if the idler caster and the chugalug tensioner are noise-free. Those rotating components accept grease filled bearings and are field of study to wearable. In addition, the mechanic volition ensure that all pulleys and accessories are turning in the aforementioned plane. These steps help brand certain your new chugalug volition operate trouble-gratuitous for its full-service life.
The belt's routing path through the various components is noted. The belt tensioner is released, unremarkably with a wrench or lever, to release the tension from the belt. With the tension off, the belt slides off the pulleys.
All rotating components — that is the alternator, air conditioner compressor, etc. — are checked for smooth operation and no dissonance.
If everything checks out, the new belt is slipped over all of the pulleys while holding the tensioner away from the belt. Once the chugalug is centered on all pulleys, the tensioner is released and the installation is consummate. The engine is run to ensure normal operation.

Is it prophylactic to drive with a serpentine belt problem?

No. Should the belt have visible damage, you risk unexpected and sudden breakage that could potentially leave you stranded. Serpentine belt bug that issue in the alternator non charging may cause the bombardment to discharge, which will result in loss of electrical power to the vehicle. Additionally, if a deteriorated belt breaks and that belt drives the water pump, the engine will overheat in a matter of seconds.

When replacing the serpentine belt keep in listen:

On many cars, the expected service life of a serpentine chugalug is effectually 90,000 miles. Should the belt neglect well prior to that, a very careful inspection should be performed to check for out-of-alignment pulleys, a mayhap out-of-position crankshaft harmonic balancer on which the bulldoze pulley is mounted, binding pulleys, or a lacking belt tensioner.
Attending should always exist given to serpentine chugalug routing, since proper routing is critical to proper chugalug tension, and function of the driven components.
Sometimes information technology is hard to distinguish serpentine chugalug related noise from other engine noises. In these cases, a mechanic will determine the origin of the noise by momentarily running the engine without the serpentine belt attached.
