Maintenance at V&F Auto: Belt Repair
Belt replacement is a key part of auto repair and preventative maintenance. Thanks to modern manufacturing, many of the belts in your engine can last months or even years but that means that replacement recommendations have also had to change and adapt.
When do my belts need to be replaced?
Most mechanics will probably suggest having an inspection of your belts done, so they can see the belts’ conditions before making a recommendation. While some repairs are more difficult to spot, most signs of belt wear can be seen just by simply popping the hood and taking a look. You might notice:Glazing Glazing, as shown in the picture above, is caused by the belt slipping. Friction between the belt and the accessory drive pulley(s) created by slipping has overheated the belt and reshaped the material.
Fraying Fraying typically indicates misalignment between the belt and the pulleys. When the belt is not properly on the pulleys, the scrapes the edges causing the edges to pull apart.
Cracks Tiny cracks in a serpentine belt aren't necessarily bad but deep ones mean it's running out of time. You should ask your mechanic to take a look to see if you need a replacement.
Any of these signs warrant immediate replacement. Once a belt starts to show the fabric cords, it is time to replace it. Belts that have been contaminated by grease or oil should also be replaced, as these fluids tend to deteriorate belt material.
