A drive belt is a seamless belt that is used to transmit torque and power from one wheel or shaft to another in a machine or any mechanical system, in this instance a vehicle. A belt drive system typically involves more than two fixed pulleys working together and is very important in the transmission of motion in a machine. In vehicles, it powers the water pump, the air conditioning, power steering, brakes and alternator among other components. It is therefore very important for vehicle owners to regularly check on the drive belt each time they changethe oil. This is to ensure that it is in proper condition and will not negatively affect the system. It is not advisable as it is risky to drive a vehicle with a worn out drive belt.

The first thing to look out for is the tension and general condition of the belt to ensure that the vehicle is always ready to perform. An over stretched belt will easily wear. There are several things to look out for when inspecting the drive belt. These are cracks, the presence of frays, missing ribs or the presence of any logged foreign material. If one observes tiny cracks in grooves, that is normal but deep fissures, splits as well as frayed edges or cracks that run parallel to the ribs should be a cause for alarm. Other warning signs include a belt that exhibits a glossy appearance or one that has some of its rib sections, half an inch or longer missing.
