"AATURBOCHARGER ASSEMBLY INSTALLATION
1. Check the internal surface, the eye bolt and the
mating surface of the oil pipe and water pipe for
clogging, and clean if necessary.
2. If deposits of carbon are accumulated on the
turbocharger oil passage, remove them and clean
using the compressed air.
Caution
Be careful not to allow foreign material to enter the
turbocharger.
3. Add clean engine oil through the oil feed pipe port
on the turbocharger.

SECONDARY COIL CHECK
NOTE
It is impossible to check the secondary coil through the
continuity check as a diode is integrated in the secondary
coil circuit of this ignition coil. So, check the secondary coil
in the following procedure.
1. Disconnect the ignition coil connector.
2. Remove the ignition coil and install a new spark plug
to the ignition coil.
3. Connect the ignition coil connector.
4. Earth the side electrode of the spark plug and crank
the engine.
5. Check that spark is produced between the electrodes of
the spark plug.
6. If no spark is produced, replace the ignition coil with a
new one and recheck.
7. If spark is produced with the new ignition coil, replace
the old one as it is faulty. If no spark is produced again,
the ignition circuit is suspected as faulty. Check the ignition
circuit.
SPARK PLUG CHECK AND CLEANING
Caution
1. The spark plug gap for iridium plugs should not be
adjusted.
2. Cleaning iridium plugs may result in damage to the
iridium tip. Therefore, if cleaning is necessary
because the plug is sooty, use a plug cleaner, and
do not clean the plug for more than 20 seconds in
order to preserve the electrodes. A wire brush should
never be used.
3. The spark plugs in GDI engines are special iridium
plugs in which the electrodes can become black even
when the plugs are working normally. Carbon which
may become deposited on these plugs burns off more
readily than with conventional plugs, and so should
not cause any problems with spark plug performance.
Judgement of whether a spark plug is operating
normally or not should be made by checking the
insulation resistance.

WARNING REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring, and interconnecting
wiring. Other SRS-related components (that mayhave to be removed/installed in connectionwith SRS service or maintenance) are
indicated in the table of contents by an asterisk(*).
