Your vehicle’s water pump, power steering pump, alternator and A/C compressor are all driven by belts, or a
single serpentine belt. The timing belt, on the other hand, is hidden under the engine’s front cover and will
need to be changed once or twice in a vehicle’s lifespan. Shop Advance for great deals on belts from top brands
like Continental, Gates and Dayco.
The serpentine belt powers accessories like the alternator, A/C compressor and water pump. It takes the place
of multiple V-belts that you'd find on pre-1990s vehicles and has the advantage of saving space under the
hood and putting less parasitic drag on the engine. The serpentine belt needs a tensioner, however, and this
tensioner has no lubrication point and can eventually seize. If you are replacing the belt, it's a good idea
to replace the tensioner at the same time.
