It is necessary to check periodically a belt condition, and at detection of defects, to replace a belt.
The belt tension is carried out automatic натяжителем and check does not require.
Switch off the engine, establish transmission in neutral position. Lift and establish the car on supports.
Note a chalk a belt on good a foreground.
Turn the engine for a pulley of a cranked shaft in a direction of rotation before position at which the cretaceous label is visible. Thus, a site behind a site examine a belt.
Fingers (and using a small lamp if it is necessary) walk on all length of a belt, feeling on presence of cracks and stratifications. Also check up, whether is not present on a belt of attritions and заполированных to shine of sites. The belt should be examined from both parties that means its necessity перекручивания for check of a condition of a seamy side. Be in passing convinced of absence of a rust, cracks and agnails on pulleys. On a working surface of a belt presence of superficial perpendicular cracks is supposed. If these cracks do not overstep the bounds of one edge and not so deep, to replace a belt there is no necessity.
The belt tension is checked by strong pressing on it by a thumb and definitions of degree of its deflection. Deflection size measure by a ruler. If the distance centre to centre pulleys makes from 180 to 280 mm the deflection size should equal 6 mm. If the distance centre to centre pulleys is in limits between 300 and 400 mm, the deflection should be 13 mm.
In the presence of one or several of the specified damages wedge it is necessarily necessary to replace a belt new.

Correctly place a belt on pulleys — it should be strictly on the pulley centre. Even short-term work of incorrectly established belt can lead to its damage.
