GENERAL DESCRIPTIONM1552000100351
The heater and cooling units are combined in a sin-
gle unit, which, with the mode film damper and flow
rate control valve in the heater unit, reduces ventila-
tion resistance, increases fan power, and decreases
noise.
SAFETY PRECAUTIONS
Wear safety goggles and gloves when servic-
ing the refrigeration system to prevent
severe damage to eyes and hands.
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 refriger-
ant recycling device.
Refrigerant R-134a is transparent and colorless in
both the liquid and vapor state. Since it has a boiling
point of
29.8C (21.64F) at atmospheric pressure,
it will be a vapor at all normal temperatures and pres-
sures. The vapor is heavier than air, non-flammable,
and non-explosive. The following precautions must
be observed when handling R-134a.
Do not heat R-134a above 40C (104.0F) or it
may catch fire and explode.
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 min-
eral oil handy when working on the refrigeration sys-
tem.1. If any liquid refrigerant gets 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.
Keep R-134a containers upright when charging
the system.
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.
A leak detector for R-134a should be used to
check for refrigerant gas leaks.
Do not allow liquid refrigerant to touch bright
metal or it will be stained.
When metering R-134a into the refrigeration system,
keep the supply tank or cans in an upright position. If
the refrigerant container is on its side or upside
down, liquid refrigerant will enter the system and
damage the compressor.
Refrigerant will tarnish bright metal and chrome sur-
faces, and in combination with moisture can severely
corrode all metal surfaces. ITEM SPECIFICATION

CHARGING M1552001200403
Use the refrigerant recovery station to charge the refrigerant.
METHOD BY USING REFRIGERANT RECOVERY
AND RECYCLING UNIT
Using the refrigerant recovery and recycling unit, refill the
refrigerant.
NOTE: Refer to the Refrigerant Recovery and Recycling Unit’s
Instruction Manual for operation of the unit.
DISCHARGING SYSTEM
Use the refrigerant recovery unit to discharge refrigerant gas
from the system.
NOTE: Refer to the Refrigerant Recovery and Recycling Unit’s
Instruction Manual for operation of the unit.
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 dis-
charge air temperature.
When a compressor is installed at the factory, it contains 140
ml 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 sys-
tem.
When the following system components are changed, it is nec-
essary to add oil to the system to replace the oil being removed
with the component.
Compressor oil: ND Oil 8
Quantity:
Evaporator: 40 ml
Condenser: 40 ml

ENGINE COOLING DIAGNOSIS
ENGINE COOLING14-4
INSPECTION PROCEDURE 2: Engine Overheating
DIAGNOSIS
STEP 1. Remove the radiator cap and check for coolant
contamination.
Q: Is the coolant contaminated with rust and oil?
YES : Replace it. Refer to P.14-27.
NO : There is no action to be taken. Go to Step 2.
STEP 2. Check the radiator cap valve opening pressure.
NOTE: Be sure that the cap is clean before testing. Rust or
other foreign material on the cap seal will cause an improper
reading.
(1) Use a cap adapter to attach the cap to the tester.
(2) Increase the pressure until the gauge indicator stops
moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93
123 kPa (14 18 psi)
Q: Does the reading remain at or above the minimum limit?
YES : Go to Step 3.
NO : Replace the radiator cap. Then go to Step 5.
STEP 3. Check thermostat operation.
Refer to 38.
Q: Does the thermostat operate correctly?
YES : Go to Step 4.
NO : Replace the thermostat, then go to Step 5.
STEP 4. Check the drive belt for slippage or damage.
Refer to GROUP 00, Maintenance Service
Drive Belts
(Check Condition). <3.8L Engine>39 .
Q: Is the drive belt loose or damaged?
YES : Adjust or replace the drive belt, then go to Step 5.
NO : There is no action to be taken.
STEP 5. Retest the system.
Check the engine coolant temperature.
Q: Is the engine coolant temperature abnormally high?
YES : Return to Step 2.
NO : The procedure is complete.

The temperature of the surface of the belt should be as
close as possible to underhood temperature.
Do not let any contaminants such as water or oil get
onto the microphone.
If strong gusts of wind blow against the microphone or
if there are any loud sources of noise nearby, the val-
ues measured by the microphone may not correspond
to actual values.
If the microphone is touching the belt while the mea-
surement is being made, the values measured by the
microphone may not correspond to actual values.
Do not take the measurement while the vehicle's engine
is running.
5. Hold special tool MB991668 (microphone) to the middle of
the drive belt between the pulleys (at the place indicated by
the arrow), about 10
20 mm (0.4 0.8 inch) away from the
rear surface of the belt and so that it is perpendicular to the
belt (within an angle of
15 degree angle).
6. Gently tap the middle of the belt between the pulleys (the
place indicated by the arrow) with your finger as shown in

Engine Oil Filter Selection
This vehicle is equipped with a full-flow, throw-away oil filter.
The same type of filter is recommended as a replacement filter
for this vehicle. It is possible, particularly in cold weather, that
this vehicle may develop high oil pressure for a short duration.
Make sure that any replacement filter used on this vehicle is a
high-quality filter. The filter must withstand a pressure of 1,800
kPa (261 psi) [manufacturer's specifications] to avoid filter and
ultimately engine damage. The Genuine Mitsubishi high-quality
filter and is strongly recommended for use on this vehicle.
Any replacement oil filter should be installed in accordance with
the oil filter manufacturer's installation instructions.
.
Oil Filter Replacement
Use care as oil could be hot.
1. Drain the engine oil by removing the oil drain plug.
2. Use an oil filter wrench to remove the engine oil filter.
3. Clean the filter bracket side mounting surface and ensure
the old O-ring has been removed.
4. Apply a small amount of engine oil to the O-ring of the new
oil filter.
5. Where the oil filter O-ring touches the oil pan flange, tighten
the oil filter to the specified torque using the
commercially-available tool.
Tightening torque:
: Approximately 3/4 turn [14
2 Nm]
6. Add new engine oil through the oil filler.
