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 John's Automotive Care 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 San Diego 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 John's Automotive Care service advisor can inspect your system and let you know if it’s time for a replacement.Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotive ... read more

The primary job of the serpentine belt for San Diego 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 San Diego 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 John's Automotive Care service advisor can inspect your belt for excessive wear and replace your serpentine belt system if it’s excessively worn.Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 9212061 ... read more

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 San Diego 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.

Any San Diego 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 San Diego 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 San Diego residents' vehicles, the serpentine belt runs the pumps for both the power steering and the power brakes. In other vehicles, the power steering ... read more
