Power-assisted steering hydraulic circuit.
The oil supplies both the steering circuit and the
suspension circuit. Petrol engine : A power-assisted steering pressure switch
is installed on the hydraulic piping, between the high
pressure pump and the steering valve.

CONDITIONING
250
ESSENTIAL: The compressor lubricant is extremely hygroscopic; always use FRESH oil.
SPECIAL FEATURES : AIR CONDITIONING SYSTEM (R 134.a)
Compressor lubricant.
Checking the compressor oil level.
There are three specific cases :
- 1/Repairs to a system without leaks.
- 2/Slow leak.
- 3/Fast leak.
1/ Repairing a system without leaks..
a) - Using draining/recovery equipment not fitted with an oil decanter.
- Drain the system as slowly as possible via the LOW PRESSURE valve, so as not to lose any oil.
- No more oil should be added when filling the system with R 134.a fluid.
b) - Using draining/filling equipment fitted with an oil decanter.
- Drain the R 134.a fluid from the system in accordance with the instructions in the equipment handbook.
- Measure the amount of oil recovered.
- Add the same amount of NEW oil when filling the system with R 134.a fluid.
c) - Replacing a compressor.
- Remove the old compressor, drain it and measure the oil quantity.
- Drain the new compressor (supplied full), so that the same amount of NEW oil is left in the compressor as was in the old compressor.
- No more oil should be added when filling the system with R 134.a fluid.
