Checking Fluid Level and Leaks (Power
steering)
Check fluid level.
Fluid level can be checked when the fluid is either hot or cold.
CAUTION:
IDo not overfill.
I Recommended fluid is Automatic Transmission Fluid
ªDEXRON
TMº type.
I Check lines for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
Greasing Steering Linkage
Apply multi-purpose grease to point shown in the illustration.
Ventilation Air Filter
FUNCTION
Air inside passenger compartment is kept clean at either recircula-
tion or fresh mode by installing ventilation air filter into cooling unit.
REPLACEMENT PROCEDURES
IRemove glove box.
Refer to BT section.
I Take out ventilation air filter which is secured with one screw,
from cooling unit.

2. Move the following parts.
ITDC sensor harness
I Power steering oil pump
3. Remove the chain cover.
I Remove the holding bolts A to C shown in the figure.
CAUTION:
While the chain cover is removed, be careful not to allow entry
of dust or foreign objects.
4. Set the No. 1 cylinder to the TDC.
1) Turn the crankshaft pulley clockwise, and match the timing indicator of the gear case to the timing mark of the crankshaft
pulley.
2) Make sure that the cam sprocket match mark is in the position shown in the figure.
I If the match mark is not in position, turn the crankshaft pulley
once more and position it.
I When removing at No. 1 cylinder TDC, each sprocket and chain
is fitted using the match mark, therefore there is no need to
apply any match marks beforehand.
5. Remove the chain tensioner.
1) Loosen upper and lower holding bolts.
2) Holding the chain tensioner in your hand, remove the upper holding bolt and release the spring tension.
3) Remove the lower holding bolt, then remove the chain ten- sioner.
I The chain tensioner does not have a mechanism which pre-
vents the ejection of the plunger. (It does have a mechanism
which prevents the plunger from returning.)
CAUTION:
Be careful not to drop the plunger and spring.

I Charge air cooler
I Air inlet pipe
I Throttle body
I Rocker cover
I Oil level gauge guide
I EGR cooler
I EGR guide tube
I EGR volume control solenoid valve
I Fuel hose
I Injection tube

I Cooling fan
I Drive belt
I Vacuum pipe
I Vacuum pump
2. Move the power steering pump.
3. Remove the harness connector from the fuel injection pump.
I After pulling the connector stopper all the way back, remove the
connector.
I When the stopper is pulled all the way back, the interlocked-
connector will come off.
As for installation, when the connector is pushed all the way
forward until the stopper locks, the interlocked-connector is
inserted.
4. Remove the fuel injection pump rear bracket.
5. Remove the chain cover.
I Remove the installation bolts A, B, and C shown in the figure
(left).
CAUTION:
During chain cover removal, seal the opening to prevent for-
eign objects from getting into the engine.
6. Fix the internal mechanism of the idler gear (scissors gear structure).
a. Remove the plug on the front side of the gear case.
b. While turning the crankshaft pulley clockwise, check the tight- ening bolt hole of the idler gear internal mechanism through the
plug hole.
I Conduct the visual check using a mirror.
I When checking, note that there are 2 other holes (with no
thread) beside the tightening bolt hole on the idler gear.

Checking Steering Wheel Play
1. With wheels in a straight-ahead position, check steering wheelplay.Steering wheel play: 35 mm (1.38 in) or less
2. If it is not within specification, check steering gear assembly when front suspension and axle, steering gear assembly and
steering column are mounted correctly.
Checking Neutral Position on Steering Wheel
CHECKING
1. Check that the steering wheel is in the neutral position whendriving straight ahead.
2. If it is not in the neutral position, remove the steering wheel and reinstall it correctly.
3. If the neutral position is between two serrated teeth, loosen tie-rod lock nut and move tie-rod in the opposite direction by the
same amount on both left and right sides to compensate for
error in the neutral position.
Front Wheel Turning Angle
Rotate steering wheel all the way right and left; measure turning
angle. Turning angle of full turns:Refer to section FA for SDS.
Checking and Adjusting Drive Belts
Refer to section MA for Drive Belt Inspection.
Checking Fluid Level
Check the fluid level in the reservoir when the engine is cold. If the
fluid level is below the MIN line, and fluid up to the MAX line.
CAUTION:
IDo not overfill the MAX level.
I Do not reuse any used power steering fluid.
I Use only ªDEXRON
TMº or equivalent.

Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-ture.Temperature: 50É - 80ÉC (122 - 176ÉF)
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360É from neutral position.Steering wheel turning force: 39 N (4 kg, 9 lb) or less
I If steering wheel turning force is not within specification,
perform the following inspection procedure:
E
Measure steering
