2.
Hold the hexagonal part of drive belt auto-tensioner pulley with a
hexagonal socket (A) securely. Then move the wrench handle in
the direction of arrow (loosening direction of tensioner).
CAUTION:
Never place hand in a location where pinching may occur if
the holding tool accidentally comes off.
3.
Insert a stopper pin (A) in diameter such as short-length screw-
driver into the hole of the retaining boss to fix drive belt auto-ten-
sioner pulley.
• Keep drive belt auto-tensioner pulley arm locked after drive
belt is removed.
NOTE:
Use approximately 3.0 mm (0.118 in) dia. hard metal pin as a
stopper pin.
4.
Remove drive belt.
INSTALLATION
1.
Install drive belt.
CAUTION:
• Check that drive belt is completely set to pulleys.
• Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
2.
Release drive belt auto-tensioner, and apply tension to drive belt.
3.
Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4.
Check that the indicator (notch on fixed side) of drive belt auto-tensioner is within the range when new
drive belt is installed. Refer to
MA-98, "DRIVE BELT : Checking"
.
ENGINE COOLANT
ENGINE COOLANT : Inspection
INFOID:0000000010503164
LEVEL
• Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
• Adjust the engine coolant level as necessary.
• Check that the reservoir tank cap is tightened.
WARNING:
Never remove reservoir tank cap when engine is hot. Serious
burns could occur from high-pressure engine coolant escaping
from reservoir tank.

Shifte air cleaner cover
to car front side and remove air
cleaner element
.
INSTALLATION
Install in the reverse order of removal.
• Insert the projection
of air cleaner element
in such a way so
that it becomes the position (upper front side of car) of illustration.
• Verify that there is no looseness in air cleaner cover and has been
fixed accurately.
• Check that pawls of air resonator are engaged.
AIR CLEANER FILTER : Inspection (Dry Paper Type)
INFOID:0000000011497306
INSPECTION AFTER REMOVAL
Examine with eyes that there is no stain, clogging, or damage on air cleaner element.
• Remove dusts (such as dead leafs) on air cleaner element surface and inside cleaner case.
• To clean air cleaner element
, blow air on it from the air intake manifold side
to remove trash or dust.
CAUTION:
• When blowing air on the air cleaner element, attach the
cover to the air cleaner case and stay away from the vehicle
as much as possible to prevent the entry of dirt into the air
cleaner case.
• Never blow air from the ambient air side to prevent clogging.
When the ambient air side needs to be cleaned, attach the
cover to the intake manifold side and lightly dust by hand.
• If clogging or damage is observed, replace the air cleaner element.

INSPECTION AFTER REMOVAL
Examine with eyes that there is no stain, clogging, or damage on air cleaner element.
• Remove dusts (such as dead leafs) on air cleaner element surface and inside cleaner case.
• If clogging or damage is observed, replace the air cleaner element.
CAUTION:
Never clean the viscous paper type air cleaner element by blowing as there is a risk of deterioration of
its performance

INFOID:0000000011497320
ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1.
Pull out oil level gauge and wipe it clean.
2.
Insert oil level gauge and check that the engine oil level is within
the range
shown in the figure.
3.
If it is out of range, adjust it.
ENGINE OIL APPEARANCE
• Check engine oil for white turbidity or heavy contamination.
• If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Oil cooler
• Intake valve timing control solenoid valve
• Exhaust valve timing control solenoid valve
• Front cover
• VTC cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and camshaft bracket
• Mating surface between camshaft bracket and rocker cover
• Mating surface between camshaft bracket and high pressure fuel pump
• Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to get burned, as engine oil may be hot.
• When checking engine oil pressure, shift position should be “Parking position”, and apply parking
brake securely.
1.
Check engine oil level.

2.
Disconnect harness connector at oil pressure sensor
, and
remove oil pressure sensor using a deep socket (commercial
service tool).
CAUTION:
Never drop or shock oil pressure switch.
3.
Install oil pressure gauge [SST: ST25051001] (A) and hose
[SST: ST25052000] (B).
4.
Start engine and warm it up to normal operating temperature.
5.
Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
If difference is extreme, check oil passage and oil pump for oil leakage.
6.
After the inspections, install oil pressure switch as follows:
a.
Remove old liquid gasket adhering to oil pressure switch and engine.
b.
Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Liquid Gasket or equivalent.
c.
Check engine oil level.
d.
After warming up engine, check that there is no leakage of engine oil with running engine.

WARNING:
• Be careful not to get burned, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1.
Warm up the engine, and check for engine oil leakage from engine components. Refer to
2.
Stop the engine and wait for 10 minutes.
3.
Loosen oil filler cap.
4.
Remove drain plug and then drain engine oil.
