How to replace poly V-belt?

As a rule, it is quite easy to replace the poly V-belt single-handedly if corresponding skills and experience are present. To do so you need to:

  • Remove the battery from the car.
  • Activate the parking brake mechanism.
  • Draw or take a photo of the belt routing scheme.
  • Loose tightening of the component by bypassing and blocking the tensioner.
  • Remove the belt from the pulleys.
  • Inspect the rollers, tensioner and pulleys visually, assess their condition, replace by necessity.
  • Check coaxial alignment of the pulleys.
  • Install a new belt, following the routing scheme adjusting its ribs with pulley grooves.
  • Provide proper tensioning of the belt. For this, you need to unblock the automatic tensioner or adjust tightening manually, using the car manufacturer’s recommendations.

Is it possible to install poly V-belt of different dimensions on your car?

On your car you can install the poly V-belt of only those dimensions, which were presupposed by the manufacturer. It is impossible to mount too wide belt on the pulley. And correctness of tensioning greatly depends on the component length. If the belt is shorter than necessary, it will be tightened too much, so tensioning and idling rollers as well as auxiliary units bearings may quickly break down. The excessively long belt also can not be properly tensioned, so it slips. Moreover, during the component selection, it is essential that spacing and its teeth profile are equal to parameters of grooves of the pulley. In order to exclude mistake, manufacturers usually apply markings of length and ribs quantity on the outer surface of the parts.

Where to find diagram of poly V-belt installation for your car? What characteristics are noted in poly V-belt marking?

Usually, a diagram of poly V-belt installation can be found in the car technical documentation. But in order to understand it you need to familiarize yourself with abbreviations and reference letters of units and assemblies, which are driven by the belt. Most car manufacturers use the following abbreviations:

  • AC – the air-conditioner compressor;
  • CS – the crankshaft;
  • G – the idling roller;
  • T – the tensioning roller;
  • F – the engine cooling system fan;
  • PAS – the power steering pump;
  • GEN – the alternator;
  • SC – the supercharger;
  • VP – the vacuum pump;
  • WP – the cooling system pump.

Usage of the corresponding scheme significantly simplifies installation of the poly V-belt.


Quantity of grooves, perimeter length of the item, the component type and name of the manufacturing company are usually noted in the poly V-belt marking. For example, the next marking: Contitech 5 PK 1546, the sign “Contitech” means that the belt is made by the same-name German company; the digit “5” is used for marking of grooves quantity, letters “PK” note that the belt is poly ribbed, and 1546 is length of the part in millimeters.
