Engine accessories are driven by a single multi-ribbed belt.
This reduces the overall length, weight and number of engine parts
Automatic tensioner eliminates the need to adjust belt tension
The automatic belt tensioner consists of a tensioning pulley, a lever and a tensioner
The idler pulley maintains the belt tension under the force of the spring, which is located in the tensioner
One of two types of mechanism can be used on a car, although their principles of operation are the same and they are interchangeable
The tension of the accessory drive belt is checked in the area between the pulleys of the generator and the power steering pump
A correctly tensioned belt should rotate 90º from the force of the fingers 15-20 N (1.5-2 kgf)
If the belt is loose, the tensioner must be replaced
When inspecting the belt, it must be replaced if tears, abrasions and cord exposure are found.
The presence of cracks on the inner ribs of the belt is considered acceptable, with the exception of the absence of fragments of the ribs
The figure shows the layout of the belt
In order to remove the belt, you need to loosen the belt tensioner using the socket by 19 by turning the key clockwise
Remove the belt and install it according to the diagram
After installation, we check the correct location of the belt ribs in the pulley streams. In case of displacement, reinstall the belt
Checking the technical suitability of the belt according to the maintenance schedule is required every 20 thousand kilometers of the vehicle.
