Knowing when to replace the drive belt on your car can save you thousands of dollars in repair costs. Regularly check the belt to avoid getting stranded -- and monster repair bills. Serpentine belts, standard V-belts and "cogged" V-belts are the three main types used.
Belts are common mechanical parts that are popular among many industries. There are various types of belts for you to choose. And some of them can also be further divided into many types such as the V Belt. It is the basic power-transmission belt, providing the best combination of traction, operating speed, bearing load, and service life.
A serpentine belt, also known as a multi-vee, poly-v, or multi-rib belt, is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator,power steering pump, water pump, air conditioning compressor, air pump, etc. The belt may also be guided by an idler pulley and a belt tensioner which may be spring-loaded, hydraulic, or manual. A serpentine belt needs to be replaced every five years or 50,000 miles. Most new cars include a diagram under the hood that explains how to replace it.
Standard V-belt is a half inch wide. Narrower than the serpentine belt, it is typically found on older automobiles. Its tapered sides fit between pulleys or gears and it works best with light loads, since the flat base does not rotate gears precisely. A standard V-belt should be replaced every three years or 36,000 miles, and replacement costs roughly half the price of a serpentine belt, according to International Auto Repair.
The cogged belt is similar to the standard V-belt, except that it has grooved base. These grooves allow a firm grip on gears and engine accessories, making the belt ideal for high-load applications. As does the standard V Belt, the cogged belt should be replaced every three years or 36,000 miles.
