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

May 28, 2018

Any Wyoming 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 Wyoming 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 Wyoming 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 Michigan 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 Wyoming 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.”
