ENGINE COOLANT LEAK CHECKING
1. Confirm that the coolant level is up to the filler neck.
Install a radiator cap tester and apply 160 kPa pressure,
and then check for leakage from the radiator hose or
connections.
Caution
(1) Be sure to completely clean away any moisture
from the places checked.
(2) When the tester is taken out, be careful not to
spill any coolant from it.
(3) Be careful, when installing and removing the tester
and when testing, not to deform the filler neck
of the radiator.
2. If there is leakage, repair or replace the appropriate part.
RADIATOR CAP OPENING PRESSURE CHECK
1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the indicator of the gauge
stops moving.
Limit: 83 kPa
Standard value: 93 - 123 kPa
3. Replace the radiator cap if the reading does not remain
at or above the limit.
NOTE
Be sure that the cap is clean before testing, since rust
or other foreign material on the cap seal will cause an
improper indication.
ENGINE COOLANT REPLACEMENT
1. Remove the under cover.
(Refer to GROUP 51 - Front Bumper.)
2. Drain the engine coolant by removing the drain plug and
then the radiator cap.

3. Remove the cylinder block drain plug from the cylinder
block to drain the engine coolant.
4. Remove the reserve tank to drain the engine coolant.
5. When the engine coolant has drained, pour in water from
the radiator cap to clean the engine coolant line.
6. Coat the thread of the cylinder block drain plug with the
specified sealant and tighten to the specified torque.
Specified sealant:
3M Nut Locking Part No. 4171 or equivalent
7. Securely tighten the radiator drain plug.
8. Install the under cover.
(Refer to GROUP 51 - Front Bumper.)
9. Install the reserve tank.
10. Slowly pour the engine coolant into the mouth of the
radiator until the radiator is full, and pour also into the
reserve tank up to the FULL line.
Recommended anti-freeze:
MITUBISHI GENUINE COOLANT or equivalent
Quantity: 6.0 L
Caution
Do not use alcohol or methanol anti-freeze or any
engine coolants mixed with alcohol or methanol
anti-freeze. The use of an improper anti-freeze can
cause the corrosion of the aluminium components.
11. Install the radiator cap securely.
12. Start the engine and warm the engine until the thermostat
opens. (Touch the radiator hose with your hand to check
that warm water is flowing.)
13. After the thermostat opens, race the engine several times,
and then stop the engine.
14. Cool down the engine, and then pour engine coolant into
the reserve tank until the level reaches the FULL line. If
the level is low, repeat the operation from step 11.
CONCENTRATION MEASUREMENT
Measure the temperature and specific gravity of the engine
coolant to check the antifreeze concentration.
Standard value: 30 - 60 % (allowable concentration range)
RECOMMENDED ANTI-FREEZE
AntifreezeAllowable concentration
MITSUBISHI GENUINE COOLANT
or equivalent30 - 60 %
Caution
If the concentration of the anti-freeze is below 30 %, the
anti-corrosion property will be adversely affected. In
addition, if the concentration is above 60 %, both the
anti-freezing and engine cooling properties will decrease,
affecting the engine adversely. For these reasons, be
sure to maintain the concentration level within the
specified range.

EVAPORATIVE EMISSION CONTROL SYSTEM
GENERAL INFORMATION
The evaporative emission control system prevents
fuel vapours generated in the fuel tank from
escaping into the atmosphere.
Fuel vapours from the fuel tank flow through the
fuel tank pressure control valve and vapour
pipe/hose to be stored temporarily in the canister.
When driving the vehicle, fuel vapours stored in
the canister flow through the purge solenoid and
purge port and go into the intake manifold to be
sent to the combustion chamber.When the engine coolant temperature is low or
when the intake air quantity is small (when the
engine is at idle, for example), the engine control
unit turns the purge solenoid off to shut off the
fuel vapour flow to the intake manifold.
This does not only insure the driveability when the
engine is cold or running under low load but also
stabilize the emission level.

EXHAUST GAS RECIRCULATION (EGR) SYSTEM
GENERAL INFORMATION
The exhaust gas recirculation (EGR) system lowers
the nitrogen oxide (NOx) emission level. When the
air/fuel mixture combustion temperature is high,
a large quantity of nitrogen oxides (NOx) is
generated in the combustion chamber. Therefore,
this system recirculates part of emission gas fromthe exhaust port of the cylinder head to the
combustion chamber through the intake manifold
to decrease the air/fuel mixture combustion
temperature, resulting in reduction of NOx.
The EGR flow rate is controlled by the EGR valve
so as not to decrease the driveability.
OPERATION
The EGR valve is being closed and does not
recirculate exhaust gases under one of the following
conditions. Otherwise, the EGR valve is opened
and recirculates exhaust gases.DThe engine coolant temperature is low.
DThe engine is at idle.
DThe throttle valve is widely opened.
