Well, it won't keep your pants up, but it does transport power to your vital automotive components. 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. If you suspect your serpentine belt is failing, watch out for the following symptoms: Squealing noise from the front of the vehicle. If you notice a squealing noise coming from the front of your vehicle, it could be from the serpentine belt. Power steering and AC not working. Engine overheating. Cracks and wear on the belt. The serpentine belt is a long, winding belt that connects many of your vehicle's components, including the power steering pump, alternator, and air conditioning compressor, and more, to the vehicle's crankshaft pulley. In some engines, the serpentine belt also runs the water pump, radiator fan, and supercharger. A broken serpentine belt leads to a sudden loss of power assist for the steering system, where the steering wheel all-of-a-sudden becomes very hard to turn. Some cars have the water pump driven off the timing belt and some cars have more than one serpentine belt, so which accessories would work and which wouldn't would vary depending upon your car and which serpentine belt was broken.. It is best to not drive a car with a broken belt, even for a short distance.

Serpentine belts are built to last—much longer than before because of advancements in rubber technology. Under ideal conditions, a belt should stick with you for an average of 60, 000 to 100, 000 miles.

Serpentine Belt Replacement Cost It is very inexpensive to replace a serpentine belt. The replacement cost is only going to be between $90 and $200 in most cases. The belt itself will cost between $25 and $75 while the labor costs will probably be between $75 and $120.

A serpentine belt does more work than a timing belt. Timing belts synchronize the movement of the crankshaft and the camshaft while the serpentine belt transmits mechanical power which drives the air conditioner, water pump, alternator, etc. A timing belt needs more work to be replaced because it is covered.

Squealing. When the engine is idling, a bad pulley may make a squealing sound. This is due to the bearings in the pulley going bad. The bearings may also make various other sounds such as clattering or even a rumbling sound, making the vehicle sound as if there was much more wrong than a bad pulley.

The average cost for a drive belt tensioner replacement is between $211 and $239. Labor costs are estimated between $73 and $93 while parts are priced between $138 and $146. Estimate does not include taxes and fees.

Inspecting your vehicle's belts and hoses and having them replaced before they fail can prevent inconvenient breakdowns and costly repairs. To help, Jiffy Lube offers engine services with serpentine belt replacement that includes the following: A visual inspection of the serpentine belt.

Effect of Serpentine Belts on Transmission. As a result, if the serpentine belt is worn out or breaks, it results in engine overheating and losing the powered steering and charging system.

Thanks to improvements in rubber technology, serpentine belts last much longer than they did back in the day. Most serpentine belts generally last between 50, 000 and 100, 000 miles. Eventually, your car's serpentine belt will wear down from continuous exposure to heat and friction and will need to be replaced.

Serpentine belt replacement is easy because today's automatic drive belt tensioners eliminate the need to loosen bolts or pry components into position for retensioning. Just rotate the tensioner, remove the old belt and install a new one.

All these can take you one and a half an hour or more. For an experienced person, it will only take about 20-minutes, as the only concern will be to understand out how to loosen the tensioner bolt, and if the belt is the right one.

Serpentine belt problems usually result from one of three causes: a defective belt tensioner; misalignment of a pulley; or, defective bearings in the tensioner, idler, or one of accessories driven by the belt (including the water pump). Excessive cracking: Other than severe old age, defective tensioner.

In most cases, it's caused by the tensioner pulley being slightly misaligned. When you replace the serpentine belt, it's important to align the pulley with the right tools; such as a serpentine belt removal tool and pulley alignment wrench.

Without a serpentine belt connected to drive these accessories your car will barely be able to function. You won't have any power steering while driving, your alternator won't be charging your battery, and your water pump won't pump water throughout your cooling system.
