3. INSPECT FLOW CONTROL VALVE ASSEMBLY
(a) Coat the flow control valve assembly with power
steering fluid and check that it falls smoothly into the
flow control valve due to its own weight.
If the control valve does not fall into the hole
smoothly, replace the vane pump assembly.
(b) Check the flow control valve assembly for leaks.
Close one of the holes and apply compressed air,
392 to 490 kPa (4 to 5 kgf/cm
2, 57 to 71 psi), into
the opposite side hole, and confirm that air does not
come out from the holes in the ends of the flow
control valve assembly.
If air leaks, replace the vane pump assembly.
4. INSPECT FLOW CONTROL VALVE COMPRESSION
SPRING
(a) Using vernier calipers, measure the free length of
the flow control valve compression spring.
Minimum free length:
29.2 mm (1.150 in.)
If the length is less than the minimum, replace the
vane pump assembly.
5. INSPECT PRESSURE PORT UNION
If the union seat in the pressure port union is severely
damaged, replace the vane pump assembly.
6. INSPECT TOTAL PRELOAD
(a) Check that the pump rotates smoothly without
abnormal noise.

Recommended service bolt:
Thread diameter:
10 mm (0.39 in.)
Thread pitch:
1.25 mm (0.0492 in.)

50 mm (1.97 in.)
(c) Using a torque wrench, check the pump rotating
torque.
Rotating torque:
0.27 N*m (2.8 kgf*cm, 2.4 in.*lbf) or less
If the rotating torque is not as specified, check the
vane pump housing oil seal.

(7) The A/C system does not function due to air in
the refrigeration system.
CAUTION:
The low-pressure piping may be very hot
and cause serious burns.
(8) The A/C system does not function effectively
due to an expansion valve malfunction.
Symptoms Probable Cause Diagnosis Corrective Actions
Pressure extremely high on both
low and high-pressure sides- Excessive refrigerant
- Cooling performance of
condenser insufficient- Condenser is dirty
- Condenser fan motor is
malfunctioning
- Excessive refrigerant1. Clean condenser
2. Check condenser fan motor
operation
3. If 1 and 2 normal, check the
amount of refrigerant and supply
appropriate volume of refrigerant
Symptoms Probable Cause Diagnosis Corrective Actions
- Pressure extremely high on both
low and high-pressure sides
- The low-pressure piping is too
hot to touchAir in refrigeration system- Air in refrigeration system
- Vacuum purging insufficient1. Check if compressor oil is dirty
or insufficient
2. Evacuate air and charge new
refrigerant

2. INSPECT COMPRESSOR OIL
(a) When replacing the compressor and magnetic
clutch with a new one, after gradually removing the
refrigerant gas from the service valve, drain the
following amount of oil from the new compressor
and magnetic clutch before installation.
Standard:
(Oil capacity inside new compressor and
magnetic clutch:
225 + 15 cc (7.6 + 0.5 fl.oz.)) - (Remaining oil
amount in the removed compressor and
magnetic clutch) = (Oil amount to be
removed when replacing)
NOTICE:
• When checking the compressor oil level,
observe the precautions on the cooler
removal / installation.
• Because compressor oil remains in the pipes
of the vehicle, if a new compressor and
magnetic clutch is installed without removing
some oil inside, the oil amount becomes
excessive, preventing heat exchange in the
refrigerant cycle and causing refrigerant
failure.
• If the remaining oil in the removed
compressor and magnetic clutch is too small
in volume, check for oil leakage.
• Be sure to use ND-OIL 8 for compressor oil.
3. INSPECT COMPRESSOR AND MAGNETIC CLUTCH
(a) Disconnect the connector from the compressor and
magnetic clutch.
