CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA
section (ªChanging Engine Coolantº, ªENGINE MAINTENANCEº). Also, replace the engine oil.
1)Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA section (ªAnti-freeze Coolant Mixture Ratioº,
ªRECOMMENDED FLUIDS AND LUBRICANTSº).
2)After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function CheckNCEC0489Use this procedure to check the overall function of the cooling fan.
During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by
turning it a quarter turn to allow built-up pressure to escape.
Then turn the cap all the way off.
With CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-SR-284.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-SR-284.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with CON-
SULT-II.
5) If the results are NG, go to ªDiagnostic Procedureº, EC-SR-
284.

2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-SR-284.
3) Start engine.
Be careful not to overheat engine.
4) Set temperature control lever to full cold position.
5) Turn air conditioner switch ªONº.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine
compartment side without removing the headlamp body.

Grasp only the plastic base when handling the bulb.
Never touch the glass envelope.
1. Disconnect the battery cable.
2. Turn the bulb retaining ring counterclockwise until it is free
from the headlamp reflector, and then remove it.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
5. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering head-
lamp body may affect the performance of the headlamp.
Remove headlamp bulb from the headlamp reflector just
before a replacement bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should
be in good repair, calibrated and operated in accordance with
respective operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is no-load in vehicle (coolant, engine oil
filled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver’s position).
CAUTION:
Be sure aiming switch is set to“0”when performing aiming
adjustment on vehicles equipped with headlamp aiming
control.

Aiming Adjustment
Before performing aiming adjustment, make sure of the follow-
ing.
a. Keep all tires inflated to correct pressure.
b. Place vehicle on level ground.
c. Check that vehicle is unloaded (except for full levels of
coolant, engine oil and fuel, and spare tire, jack, and tools).
Have the driver or equivalent weight placed in driver’s seat.
1. Set the distance between the screen and the center of the
fog lamp lens as shown at left.
2. Turn front fog lamps ON.
3. Adjust front fog lamps so that the top edge of the high inten-
sity zone is 100 mm (4 in) below the height of the fog lamp
centers as shown at left.

When performing adjustment, if necessary, cover the head-
lamps and opposite fog lamp.

Parts Requiring Angular Tightening
ISome important engine parts are tightened using an angular-
tightening method rather than a torque setting method.
IIf these parts are tightened using a torque setting method,
dispersal of the tightening force (axial bolt force) will be two or
three times that of the dispersal produced by using the correct
angular-tightening method.
IAlthough the torque setting values (described in this manual)
are equivalent to those used when bolts and nuts are tightened
with an angular-tightening method, they should be used for
reference only.
ITo assure the satisfactory maintenance of the engine, bolts
and nuts must be tightened using an angular-tightening
method.
IBefore tightening the bolts and nuts, ensure that the thread
and seating surfaces are clean and then coated with engine oil.
IThe bolts and nuts which require the angular-tightening
method are as follows:
(1) Cylinder head bolts ..... SR, CD, QG
(2) Main bearing cap bolts ..... SR
(3) Connecting rod cap nuts ..... SR, QG
Liquid Gasket Application Procedure
a. Before applying liquid gasket, use a scraper to remove
all traces of old liquid gasket from mating surface and
groove, and then completely clean any oil stains from
these areas.
b. Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
IBe sure liquid gasket is 4.0 to 5.0 mm (0.157 to 0.197
in) wide for SR engine and 3.5 to 4.5 mm (0.138 to
0.177 in) wide for QG and CD engine (for oil pan).
IBe sure liquid gasket is 2.0 to 3.0 mm (0.079 to
0.118 in) wide (in areas except oil pan).
c. Apply liquid gasket to inner surface around hole perim-
eter area.
(Assembly should be done within 5 minutes after coat-
ing.)
d. Wait at least 30 minutes before refilling with engine oil
and engine coolant.
