GENERAL INFORMATION
DThe steel fuel tank is located under the floor of the rear seats to provide increased safety and increase
the amount of luggage compartment space.
DThe fuel tank has been equipped with a valve assembly which incorporates a fuel cut-off valve to
prevent fuel from leaking out in the event of a collision for adjusting the pressure inside the fuel
tank.
DThe fuel pump module contains a fuel pump, fuel filter, and fuel pressure regulator.

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.
