When To Replace Your Serpentine Belt
Posted on September 10,18 by cccadmin
You know that long belt that snakes around the front of your engine? It’s called the serpentine belt. The serpentine belt is driven by the engine as it turns. It powers your alternator, air conditioning compressor and power steering pump. On some vehicles, it also runs the water pump, radiator fan and power brakes. Sounds like a lot stuff doesn’t it?
If your serpentine belt were to break on one of our Glenwood Springs roads, your battery would die after just a short distance. If it runs your fan and water pump, your engine could overheat. And steering and braking could be more difficult. Obviously, the best things is to replace your serpentine belt before it breaks. Check your owner’s manual for when it’s recommended that you replace your serpentine belt- or just ask your Jim’s Automotive Service Advisor by calling 970-945-6666. We can inspect the belt as well, as to see if it’s in trouble.
You may have been told by a service advisor in Glenwood Springs to look for cracks on your belt to see if it needs to be replaced. Of course, cracks are still a concern, but modern belt material doesn’t crack as often as old belts did. What we look for these days is the thickness of the belt. We have a special tool at Jim’s Automotive that measures the depth of the grooves in the belt to see if it needs replacing.
A worn belt can slip or misaligned, putting undue stress on the accessories it runs. Now you can imagine its important for the belt to be tight so there’s a tensioner pulley on your engine that puts pressure on the belt to keep it at the right tension. The spring on the tensioner wears out over time, so we recommend replacing the tensioner pulley at the same time as the serpentine belt. Replacing your serpentine belt on schedule, or when an inspection warrants, it will keep you from an unexpected breakdown. Stop by or give us a call.
