Serpentine Belt

Ask PDR: What Happens When a Serpentine Belt Breaks?

The serpentine belt is aptly named since it snakes around under your hood. It may lack its namesake's fangs, but it sure packs a wallop when it breaks.

The serpentine belt powers a lot of engine systems. It runs the alternator, which charges the battery; the water pump (on some vehicles), which cools the engine; the air conditioning, which cools the driver and passengers; and the power steering pump, which allows for easier steering. When the belt breaks, all of these systems shut down.

Okay, so maybe you can live without air conditioning and power steering for a while, but your battery can't live very long without an alternator, and when the cooling system goes down, your vehicle engine will overheat. That's why Urbana drivers should never wait to get a serpentine belt replaced.

Serpentine belts are fairly inexpensive at PDR in Urbana. And they look downright cheap when you compare them to the cost of an overheated vehicle engine, a tow truck, time lost on the road, inconvenience, and the potential safety consequences of being stranded.

Good car care means never putting off preventive maintenance. Do yourself a favor. Ask your friendly and knowledgeable PDR  technician to glance under your hood and give that serpentine belt a quick look-over.

Urbana Car Owners Ask: Why Do I Need to Change My Serpentine Belt?

Any Urbana driver who understands preventive maintenance knows that “if it ain't broke, don't fix it” is bad auto advice. Replacing a part before it breaks is much less costly for Urbana residents than repairing the engine damage that comes after a part breaks or fails. A good example of this is the serpentine belt.

The serpentine belt gets its name because of its circuitous path around the engine. The serpentine belt is driven by the engine and powers a number of systems, as follows:

1. The serpentine belt spins the compressor that generates the cool air for the air conditioning system.
2. The serpentine belt powers the alternator. The alternator generates electricity for use in the vehicle's electrical systems and to charge the battery. Without the alternator, the battery wouldn't last more than a few miles.
3. In many Urbana residents' vehicles, the serpentine belt runs the pumps for both the power steering and the power brakes. In other vehicles, the power steering pump may be electric and the power brakes may use a vacuum boost.
4. On many vehicles, the serpentine belt powers the water pump. The water pump keeps coolant circulating through to maintain appropriate operating temperatures. In some Illinois vehicles, a timing belt runs the water pump.

When a serpentine belt fails, all of these systems fail as well, which can lead to engine impact.

Replacing parts before they break saves money for Urbana residents by preventing more repairs and the frustration of having your vehicle in the shop for an extended period of time. If you're looking for an adage to apply to good car care, you might remember the old story of how “for want of a nail, the kingdom was lost.”

Automotive Tips from PDR: Serpentine Belt Tensioner

The serpentine belt tensioner applies pressure to the serpentine belt, maintaining optimal tension to drive the accessories like the alternator and A/C compressor. At PDR we know that the service life of the belt tensioner is the same as the belt itself, so they should always be replaced together. A worn tensioner prevents the accessories from spinning properly, leading to premature wear and noise for Urbana drivers.

Your vehicle manufacturer has a recommended mileage interval for serpentine belt replacement. A complete accessory drive system service replaces the serpentine belt, the belt tensioner and any idler pulleys your car might have. Your friendly and professional PDR service advisor can inspect your system and let you know if it’s time for a replacement.

Automotive Tips from PDR: Serpentine Belt Overview

The technicians at PDR know your serpentine belt drives important engine accessories like your alternator, air conditioning compressor, and power steering. In some cars it may also power the power brakes or water pump. The serpentine belt is powered by the engine and winds around pulleys and the accessories. Some cars in Urbana have two serpentine belts.


The serpentine belt, the belt tensioner (which maintains the appropriate tension on the belt) and the idler pulleys are together known as the accessory drive system.

Now your serpentine belt and the belt tensioner will just wear out over time – that’s why your vehicle manufacturer has a scheduled belt replacement interval. The team at PDR in Urbana can inspect your serpentine belt for wear and get it replaced if it’s time.

Automotive Tips from PDR: Serpentine Belt System Wear

The primary job of the serpentine belt for Urbana drivers is to provide important traction to spin the accessories. As the belt wears it loses some of its grip and the accessories may not spin at optimal speeds. For example, if your alternator doesn’t spin fast enough, the battery will not completely recharge while you’re driving and you could end up stranded around Urbana with a dead battery.

In short, a worn serpentine belt will stress all of the accessories it powers leading to premature wear and possible early replacement. When as little as 5% of belt material is lost, the serpentine belt cannot provide the proper traction for the accessories. Your friendly and professional PDR service advisor can inspect your belt for excessive wear and replace your serpentine belt system if it’s excessively worn.
