Serpentine Belt

June 22, 2020 by Denver Express Car Care

Your serpentine belt is powered by the engine as it turns.  Your alternator, air conditioning compressor and power steering pump depend on your serpentine belt in order to run.  On some vehicles it also runs the water pump, radiator fan and power brakes.

If your serpentine belt breaks, your battery won’t last long.  If it runs your fan or water pump, your engine could overheat before your battery dies.  Steering and braking would also be affected.  To put it mildly, you could be up a creek without a paddle if your serpentine belt breaks.  Hopefully, we’ve made an impression about how important it is to replace your serpentine belt before it’s worn out.

Your owner’s manual will advise you when they recommend it’s best to replace your serpentine belt.  Your friendly and knowledgeable service adviser at Express Car Care can inspect the belt as well to determine if it’s close to failure.

You may have heard that it’s a good idea to check for cracks in your belt to see if it’s time for a new one.  However, with the newer belts, belt thickness is a more reliable indicator of the status.  At Express Car Care, we use a special tool to measure the depth of the grooves to see if a replacement is in order.

A worn belt can also cause problems even before it breaks.  It can slip out of place and put undue stress on the accessories it runs.

There’s a tensioner pulley on your engine that puts pressure on the belt to keep it at the right tension.  Since the spring on the tensioner wears out like any other part, we recommend replacing the tensioner pulley at the same time you switch out the serpentine belt.

Replacing your serpentine belt on schedule will save you from a dangerous breakdown.

Come in and let us help you keep your vehicle on the road.
