In accordance with the maintenance regulations, we check the condition of the air conditioning compressor drive belt every 10 thousand kilometers. The belt should not have cracks, tears or delamination of rubber from the fabric base. From the bottom of the car, remove the mudguard of the engine compartment (see Removing the mudguards). Check the tension of the A/C compressor drive belt.
When you press your finger on the belt in the middle between the auxiliary drive pulleys and the compressor with a force of about 10 kgf, the belt deflection should be 5–8 mm.
To tension the belt..
... with a "14" ring wrench, loosen the nut securing the tension roller axis.
Turning the adjusting bolt clockwise with a spanner wrench or a "12" head, we tighten the belt.
After tensioning the belt, tighten the nut of the tension roller axle. To replace the belt, loosen its tension by turning the adjusting bolt counterclockwise with the nut of the tension roller axis released.
Remove the belt from the tension roller.
Remove the belt from the pulleys.
We install the belt and the mudguard of the engine compartment in reverse order.
