Tips on checking a drive belt

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 change the 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. Additionally, one should ensure that they inspect the entire length of the belt surface. If any of the above mentioned elements are observed then it is time to change the drive belt. Sometimes, the vehicle may produce a squealing sound. This typically points out to a loose or worn out drive belt. This is because a loose belt may slip and subsequently produce a squealing sound, causing the alternator to vibrate rapidly, thereby wearing it out more easily. If the squeal emanates from underneath the hood, then it is highly probable that the drive belt is either loose or damaged and it will need to be replaced. Belts are in essence supposed to run for up to 50, 000 miles but if signs of wear are observed then it is advisable to replace it.Even though it is important to have the car checked by a certified repair shop, it is also important to be proactive and inspect the drive belt personally. Thus, if the drive belt is to be replaced one could either replace the belt personally or hire mechanic to replace it. This is very important as goes a long way in preventing problems related to the drive belt and acts to maintain the vehicle. However, as a safety precaution, always turn off the engine before belt inspection and do not work around an electric fan if the engine has not cooled off completely. To ensure that the fan does not engage during check up, it is important to disconnect it.
