Auxiliary Drive Belts & Serpentine Belts

If you've never heard of a drive belt, there's certainly something useful for everyone to know about that essential car part. Actually, the drive belt is a loop of flexible rubber that routes around a series of pulleys and runs your alternator, water pump, power steering pump, air pump, and an A/C compressor. Older autos have several V-shaped drive belts per each device, whereas in newer vehicles, engine-mounted accessories are controlled by a serpentine belt.

Unfortunately, drive belts are not everlasting. It especially applies to the vehicles with a single serpentine belt: if that one fails, the water pump won't be in action, hence you risk overheating your car. As far as you know, it's not that safe to drive when the engine is hot. Besides, steering will be really hard. If, however, you have an old-style setup comprised of individual belts, you will probably be able to drive a couple of miles and get to the service center.

We aim to provide our customers with the finest Auxiliary Drive Belts & Serpentine Belts the industry can offer, which is why we accept no compromise when it comes to the quality. Created by the most reputable names in the industry, such as Dorman, Continental ContiTech, Gates, Dayco, Bando, Mitsuboshi the Auxiliary Drive Belts & Serpentine Belts we've gathered for you feature precise design and everlasting durability.


Let's find out why drive belts can wear out or even get completely damaged, how to know when you need a new part, and finally, what should be done to extend the service life of the belts. Heat accumulation in the engine compartment is destructive to the belt and will eventually result in its failure. Also, the trouble can be due to improper tension. Engine oil leakage and the pieces of debris stuck between the ribs of the belt are likely to add fuel to the fire.

A good piece of advice is to consider any uncommon sounds alarming you of the belt's troubles. A squealing or whistling noise wins the first place. They are usually noticeable when starting the engine or turning the steering wheel to the limit. You may also hear a chirping noise after driving in the rain. Finally, a buzzing noise is due to a worn out bearing inside the tensioner. If you remove the drive belt and see cracks, tears, or cuts on its underside, it's high time you installed a new part.

So, when exactly do you need to get rid of the old belt? On the average, any V-belt should be serviced every 36,000 miles, however, serpentine belts can boast of a longer lifespan, say, from 40,000 to 50,000 miles. Replacing a drive belt may become your second nature. But if you're a newbie in such kind of job, look first in the owner's manual to study a routing diagram, which is a key to the successful replacement. Though, if you have no idea what should be done to the forest of the pulleys and how to route the belt, then seek the help of your mechanic.

Guides & Articles
Look up "fan belt" in any modern automotive dictionary, and you'll typically find a definition that reads, "An endless belt used to transmit power from a crankshaft-driven pulley to a pulley driving the fan, alternator, or other engine accessory. It is usually V-shaped in cross section with the point of the V fitting into a groove in the pulley".
This article will guide you through a generic tune up on most any car or light duty gasoline-powered vehicle built within the last 20 years or so. We will presume that you are tuning up your engine because it has reached the mileage or time point to do so, and that you are NOT performing a tune up to cure an engine performance defect. We make this distinction...
Internal combustion engines are extremely complex and feature a wide array of components that rotate, move up and down, pump, seal, or remain stationary. When repairing or rebuilding your engine, you will come across many different terms when referencing repair manuals and ordering parts. We know it can be confusing, especially when the repair is complex. Even if...
