- the pipes and connectors for the fast idle and
EGR solenoid valves,
- the brake servo pipe,
- the accelerator and clutch cables,
- the diesel fuel filter connector,
- the compressor feed wire (if fitted).
Remove:
- the cooling assembly (see section 19
"Radiator"),
- the alternator belt (see section 16),
- the compressor mounting bolts (if fitted) and
attach it to the front cross member.
NOTE: cut the base of tool Mot. 1159 to 30 mm.
