Note
It is not necessary to open the refrigerant circuit to remove and fit the
air conditioning system magnetic clutch
N25
. Refrigerant hoses remain connected.
If refrigerant circuit is opened for another reason, it is better to repair magnetic clutch with air conditioner compressor removed. If the air conditioner compressor has to be removed, take the vehicle to a workshop with suitable equipment and specially trained mechanics because the refrigerant must be extracted using, for example,
air conditioning service station
VAS 6007A
.
The clearance must be redetermined after the
air conditioning system magnetic clutch
N25
has been installed.
