Removal and Installation of Front Oil SealABS004X5
REMOVAL
1. Remove the following parts:

Front engine undercover (With power tool)

Drive belt; Refer to EM-15, "DRIVE BELTS" .
2. Remove crankshaft pulley with the following procedure:
a. Remove rear cover plate (2WD) or starter motor (AWD) and set
ring gear stopper (SST) as shown in the figure. Refer to SC-10,
"STARTING SYSTEM" .
b. Loosen crankshaft pulley bolt and locate bolt seating surface as
10 mm (0.39 in) from its original position.
CAUTION:
Do not remove crankshaft pulley bolt as it will be used as a
supporting point for suitable puller.
c. Place suitable puller tab on holes of crankshaft pulley, and pull
crankshaft pulley through.
CAUTION:
Do not put suitable puller tab on crankshaft pulley periph-
ery, as this will damage internal damper.

in figure.
INSPECTION AFTER INSTALLATION

Before starting engine, check the levels of engine coolant, engine oil and working fluid. If less than
required quantity, fill to the specified level.

Use procedure below to check for fuel leakage.
–Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil, working fluid,
fuel and exhaust gas.Slinger bolts:

SHAFT END PLAY" .

Loosen bolts in several different steps.
a. Remove cover attached to the rear left side of cylinder block
(next to the starter motor housing).
NOTE:
Bolts (No. 27 shown in the figure) are installed on the inside of
cover.
b. Loosen side bolts (M10) starting from 30 to 21 to remove.
c. Loosen main bearing cap sub bolts (M9) starting from 20 to 11 to
remove.

CAUTION:AKS007MT

Installation or removal of the connector must be done with the lighting switch OFF.

When the lamp is illuminated (when the lighting switch is ON), do not touch the harness, HID control unit,
inside of the lamp, or the lamp metal parts.

To check illumination, temporarily install lamp in the vehicle. Be sure to connect power at the vehicle-side
connector.

If the error can be traced directly to the electrical system, first check for items such as burned-out fuses
and fusible links, broken wires or loose connectors, pulled-out terminals, and improper connections.

Do not work with wet hands.

Using a tester for HID control unit circuit trouble diagnosis is prohibited.

Disassembling the HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.

Immediately after illumination, the light intensity and color will fluctuate, but there is nothing wrong.

When the bulb has reached the end of its lifetime, the brightness may drop significantly, it may flash
repeatedly, or the light may turn a reddish color.
