ENGINE COOLING -GeneralInformation/
Service Specifications/Lubricant/Sealant14-2
GENERAL INFORMATION
The cooling system is designed to keep every part
of the engine at appropriate temperature in
whatever condition the engine may be operated.
The cooling method is of the water-cooled, pressure
forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the
engine. If the coolant temperature exceeds the
prescribed temperature, the thermostat opens to
circulate the coolant through the radiator as well
so that the heat absorbed by the coolant may be
radiated into the air.The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft.
The radiator is the corrugated fin, down flow type.
The cooling fan is controlled by the radiator fan
controller and engine-ECU depend on driving
conditions.

ON-VEHICLE SERVICE
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.
