Removing the condenser-fluid tank line
Installation Location
Scheme 104
Note. When loosening or tightening the M8 refrigerant lines on the condenser, always counter with a 21-mm open-ended wrench.
Scheme 105
1. Unscrew the fastening screw -1- for the line condenser and pull the line out of the condenser. (Scheme 106)
2. Pull the line out of the line holder.
Scheme 106
3. Counter the fastening nuts -2- and open carefully. (Scheme 107)
Note. Before re-installing the component, check the O-rings of the refrigerant lines for damage and replaced them if necessary. Wet the O-rings of the refrigerant lines with refrigerant oil. Do not open the plugs for the lines and connections until shortly before installation. Close off all lines and connections using suitable plugs during removal.
Scheme 107
4. Pull the line and the rubber sleeve out of the passage to the plenum panel over the wheel housing.
Scheme 108
1. Push line into the plenum panel via the wheel housing and press rubber sleeve into place. Ensure that rubber sleeve is fitted correctly.
Note. When loosening or tightening the M8 refrigerant lines on the condenser, always counter with a 21-mm open-ended wrench.
