REASSEMBLY
1. INSTALL THERMISTOR TO EVAPORATOR
2. INSTALL EVAPORATOR
(a) Install the plate to the evaporator.
(b) Install the evaporator on the insulator.
(c) Connect the heater case with the 13 screws.

one when the A/C unit is reassembled.
(d) Install the 2 new packings.
(e) Install the grommet to evaporator.
HINT:
If evaporator is replaced, add compressor oil to the compressor.
Add 40 ± 50 cc (1.4 ± 1.7 fl.oz.)
Compressor oil: ND ± OIL 8 or equivalent
3. INSTALL EXPANSION VALVE
(a) Lubricate 2 new O±rings with compressor oil and install
the tubes.
(b) Install the liquid tube and suction tube on the expansion
valve.
(c) Using a knife, cut off packing paper of packing while peel
off the paper, as shown in the illustration.
HINT:
Leave the packing paper untaped on the tube side so that the
installation bolt hole for remains visible.
(d) Apply new packing.
NOTICE:
Do not overtape the packing beyond the expansion valve
edge.

ON±VEHICLE INSPECTION
1. CHECK QUANTITY OF GAS DURING REFRIGERATION CYCLE
2. SET ON MANIFOLD GAUGE SET (See page AC±19)
3. RUN ENGINE
Run the engine at 1,500 rpm for at least 5 minutes.
Then check that the high pressure reading is 1.37 ± 1.57 MPa (14 ± 16 kgf/cm
2, 199 ± 228 psi).
4. CHECK EXPANSION VALVE
If the expansion valve is faulty, the low pressure reading will drop to 0 kPa (0 kgf/cm
2, 0 psi).
HINT:
When the low pressure drops to 0 kPa (0 kgf/cm
2, 0 psi), check the receiver's IN and OUT sides is no temper-
ature difference.

A/C UNIT (See page AC±27)
3. REMOVE BLOWER UNIT (See page AC±35)
4. REMOVE EXPANSION VALVE
(a) Remove the piping clamp.
(b) Ply out the packing.
HINT:
Do not reuse the packing.
(c) Using a hexagon wrench, remove the 2 bolts and sepa-
rate the expansion valve and evaporator.

4. INSTALL BLOWER UNIT (See page AC±38)
5. INSTALL GLOVE COMPARTMENT
(See page BO±81)
6. CONNECT LIQUID TUBE AND SUCTION TUBES TO
A/C UNIT (See page AC±33)
7. EVACUATE AIR FROM REFRIGERATION SYSTEM
AND CHARGE SYSTEM WITH REFRIGERANT
Specified amount: 800 ± 50 g (28.22 ± 1.76 oz.)
8. INSPECT FOR LEAKAGE OF REFRIGERANT
Using a gas leak detector, check for leakage of refrigerant.
If there is leakage, check the tightning torque at the joints.

DTC P1190 Fuel Pressure Regulator Malfunction
CIRCUIT DESCRIPTION
The fuel pressure regulator regulates the fuel pressure by reducing the pressure of the compressed fuel from
the fuel tank to the fuel injection pressure, which is 785 kPa (8 kgf/cm
2, 114 psi).
Similar to the fuel shutoff valve for the fuel tank, a fuel shutoff valve is provided on the fuel inlet side of the
fuel pressure regulator to shutoff the supply of fuel when the engine is stopped or during abnormal condi-
tions.
A reservoir that traps the moisture and oil in the fuel is provided on the low pressure side.
A built±in relief valve is provided to protect the parts located on the low pressure side.
While the fuel pressure is being reduced by the fuel pressure regulator, the Joule±Thompson effect
associated with the expansion of the fuel causes the fuel pressure regulator to be cooled excessively, exert-
ing unfavorable influence on the rubber parts such as diaphragms and fuel hoses.
Therefore, to raise the fuel temperature, a water passage is provided in the fuel pressure regulator to allow
the engine coolant to warm the regulator.
