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
