Note| t | Remove and install V-ribbed belt → Engine, Mechanics; Rep. Gr.13 |
| t | Mark the direction of rotation before removing the V-ribbed belt, the reversal of the direction of rotation can lead to the damage of the belt. |
| t | The stroke of piston of the compressor is variable, it adjusts itself depending upon the determined refrigerating capacity. |
| t | If a new compressor was installed or new refrigerant oil was filled into the compressor (e. g. after blowing through the refrigerant circuit and emptying the compressor via the oil drain plug), the compressor must be turned by hand approx. 10 turns after installing (in order to avoid damage to the compressor before operation). |
