Poly-V belts are used in cars in order to transmit torque with a greater force. Poly-V belt is considered to be a drive of all major auxiliary units - generator, oil pump, coolant pump. In vehicles with a climate system they are drive of the climatic compressor.

Due to the peculiarities of their structure, poly-v belts can withstand fairly substantial longitudinal loads. To date, poly-V belts are the result of a long work of engineers and developers to improve the elements of the drive. Belts of this type combine the high flexibility of flat belts with improved power transmission of the V-belts. On the surface poly-V belts are notable for flat outer surface and wedge-shaped longitudinal ribs on the inside surface. To improve performance and increase durability, the poly-V belt is reinforced with a rope cord.

So, the poly-V belt provides a greater capacity to the drive. Due to the design with a truncated profile of the wedge section, poly-V belts have increased flexibility, reduced heat generation and an increased resistance to cracking.

Use of high-quality poly-V belts will reduce the cost of car repairs. If you have a need to replace the poly-V belt in your car, do not waste time for shopping or garages. Contact our online store.

What is necessary to know about V-belt replacement: lifetime limits, common defects and their signs, tips and recommendations

No exact lifetime limits are presupposed for the V-belt. However, specialists recommend to inspect this part every 50,000 – 80,000 kilometers of mileage. The drive V-belt is replaced due to appearance of abrasions and cracks on its surface, delamination, breakage of reinforcing fibers.

Poor condition of the component is indicated by foreign noise under the bonnet: whistling or screeching. Moreover, failures of power supply may occur in the car electric system. This can be noticed by, for example, the fact that the battery charge stops.

Check of the V-belt lies in its visual inspection. If part edges are irregular and there are mechanical damages on the surface, the belt should be replaced. In many cases, necessity of new component installation is indicated by tensioning loosening.

It is better to entrust replacement to specialists, as it is important to follow the appropriate procedure during installation of the alternator drive belt. Moreover, proper adjustment of tensioning and positioning of the part will be required. By necessity, specialists will also replace the idle and tension rollers.
