Why Perform a Serpentine Belt Diagnosis Every 50,000 Miles?

A serpentine belt is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air pump, etc. The belt may also be guided by an idler pulley and/or a belt tensioner (which may be spring-loaded, hydraulic, or manual).

By using a single, wider belt instead of multiple, thinner belts, the belt may be put under increased tension without stretching. Higher tension reduces slip, which increases belt life and mechanical efficiency. Reduced slip can allow the use of lower-ratio pulleys; this reduces the load on the engine, increasing fuel economy and available power. The drawback of this single belt is that if the belt breaks or is knocked loose, the vehicle instantly loses multiple critical functions.

Still not sure if your vehicle’s serpentine belt needs servicing? Read our FAQ’s:

I can visually confirm there is cracking in the ribs of my serpentine belt. Now what?

Continuous exposure to high temperatures and the stress of bending around the pulleys leads to cracking. Cracks begin at the rib top and grow to the cord line. As a rule, if cracks appear 1 or 2cm apart, 80% of the life is gone and the belt should be replaced.

My belt has lost material (visually confirmed). Am I safe to drive?

There are a number of causes, including misalignment, new belt on worn pulleys, lack of tension or a combination of these factors. Pilling will occur most frequently in diesel engines, but is not isolated to them.

A local tech inspected my serpentine belt and noticed uneven wear – what’s the cost to replace

A foreign object (i.e. a pebble) in the pulley will cause uneven wear and can cut into the belt and break the tensile cords. Cars where the engine protection shield is missing are likely to have this problem.
