DISCHARGING SYSTEM Use the refrigerant recovery unit to discharge refrigerant gas from the system. REFILLING OF OIL IN THE A/C SYSTEM Too little oil will provide inadequate compressor lubrication and cause a
compressor failure. Too much oil will increase discharge air temperature.
When a compressor is installed at the factory, it contains 140 cm
3 (4.7 fl.oz) of
refrigerant oil. While the A/C system is in operation, the oil is carried through the
entire system by the refrigerant. Some of this oil will be trapped and retained in
various parts of the system.
When the following system components are changed, it is necessary to add oil to
the system to replace the oil being removed with the component.
Compressor oil: SUN PAG 56

ADJUSTMENT 1. Select a quiet area for testing. Duplicate conditions as much as possible.
Switch the compressor on and off several times to clearly identify compressor
noise. To duplicate high ambient conditions (high head pressure), restrict air
flow through the condenser. Install a manifold gauge set to make sure
discharge pressure doesn't exceed 2,070 kPa (300.2 psi).
2. Tighten all compressor mounting bolts, clutch mounting bolt, and compressor
drive belt. Check to assure clutch coil is tight (no rotation or wobble).
3. Check refrigerant hoses for rubbing or interference that can cause unusual
noises.
4. Check refrigerant charge. (Refer to
CHARGING
and
DISCHARGING
).
5. Recheck compressor noise as in Step 1 .
6. If noise still exists, loosen compressor mounting bolts and retighten. Repeat
Step 1 .
7. If noise continues, replace compressor and repeat from Step 1 .

GENERAL DESCRIPTION For the heater and air conditioning system, the heater and cooling units are
combined in a single unit, which, with the a mode film damper and flow rate control
valve in the heater unit, reduces ventilation resistance, increases fan power, and
decreases noise. AUTOMATIC AIR CONDITIONING GENERAL DESCRIPTION

SAFETY PRECAUTIONS Because R-134a refrigerant is a hydro fluorocarbon (HFC) which contains
hydrogen atoms in place of chlorine atoms, it will not cause damage to the ozone
layer.
Ozone filters out harmful radiation from the sun. To assist in protecting the ozone
layer, Mitsubishi Motors Corporation recommends an R-134a refrigerant recycling
device.
Refrigerant R-134a is transparent and colorless in both the liquid and vapor state.
Since it has a boiling point of -29.8°C (-21.64°F) at atmospheric pressure, it will be
a vapor at all normal temperatures and pressures. The vapor is heavier than air, non-
flammable, and no
n-ex
plosive. The followin
g precautions must be observed when

WARNING:Wear safety goggles and gloves when servicing the
refrigeration system to prevent severe damage to
eyes and hands.

handling R-134a.
R-134a evaporates so rapidly at normal atmospheric pressures and temperatures that
it tends to freeze anything it contacts. For this reason, extreme care must be taken to
prevent any liquid refrigerant from contacting the skin and especially the eyes.
Always wear safety goggles when servicing the refrigeration part of the A/C
system. Keep a bottle of sterile mineral oil handy when working on the refrigeration
system.
1. Should any liquid refrigerant get into your eyes, use a few drops of mineral oil
to wash them out.
R-134a is rapidly absorbed by the oil.
2. Next splash your eyes with plenty of cold water.
3. Call your doctor immediately even if irritation has ceased.
In most instances, moderate heat is required to bring the pressure of the refrigerant
in its container above the pressure of the system when charging or adding
refrigerant.
A bucket or large pan of hot water not over 40°C (104.0°F) is all the heat required
for this purpose. Do not heat the refrigerant container with a blow torch or any other
means that would raise temperature and pressure above this temperature. Do not
weld or steam-clean on or near the system components or refrigerant lines.
WARNING:Do not heat R-134a above 40 °C (104.0 °F) or it may
catch fire and explode.
CAUTION: Keep R-134a containers upright when charging the
system.
WARNING:The leak detector for R-134a should be used to
check for refrigerant gas leaks.
CAUTION: Do not allow liquid refrigerant to touch bright metal

>>C<< FUEL HIG
H-PRESSURE HOSE INSTALLATION
1. When connecting the fuel high-pressure hose to the fuel rail, apply a small
amount of new engine oil to the O-ring and then insert the fuel high-pressure
hose, being careful not to damage the O-ring.
2. While turning the fuel high-pressure hose to the left and right, install it to the
fuel rail.
3. Check that the injector turns smoothly. If it does not turn smoothly, the O-ring
may be trapped. Remove the fuel high-pressure hose and then re-insert it into
the fuel rail and check again. INSPECTION Check the following points; replace the part if a problem is found. INTAKE MANIFOLD CHECK 1. Check for damage or cracking of any part.
2. Clogging of the negative pressure (vacuum) outlet port, or clogging of the
exhaust gas recirculation passages.
3. Using a straight edge and feeler gauge, check for distortion of the cylinder
head installation surface.
Standard value: 0.15 mm (0.006 inch) or less
Limit: 0.20 mm (0.008 inch)
CAUTION:
Be careful not to allow any engine oil to enter the
fuel rail. Be careful not to bend the fuel high-pressure
hose as it is made of plastics.

2. Bleed air, then turn the steering wheel several times while the vehicle is not
moving so that the temperature of the fluid rises to approximately 50 - 60°C
(122 - 140°F).
3. Start the engine and idle it at 700 +/- 100 r/min.
4. Fully close the shut-off valve of the pressure gauge and measure the oil pump
relief pressure to confirm that it is within the standard value range. Open it
again immediately after checking the pressure.
Standard value: 9.3 - 9.8 MPa (1,349 - 1,421 psi)
CAUTION: The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.
