When drain all of engine coolant in the system, open water drain plug on cylinder block. Refer to
EM-82, "
CYLINDER BLOCK" .
3. Remove reservoir tank and drain engine coolant.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to CO-10, "
FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.

If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-82, "CYLIN-
DER BLOCK" .
2. Fill radiator and reservoir tank to specified level.

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (1-3/4 lmp qt) a minute to allow air
in system to escape.

Use Genuine Nissan Anti-freeze Coolant or equivalent
mixed with water (distilled or demineralized). Refer to
MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS".
3. Warm up engine to normal operating temperature with radiator cap installed.
4. Run engine at 3,000 rpm for 10 seconds and return to idle speed.

Repeat two or three times.
CAUTION:
Watch water temperature gauge so as not to overheat the engine.
5. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using a fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.
6. Refill reservoir tank to “MAX” level line with engine coolant.
7. Repeat steps 2 through 5 two or more times with radiator cap installed until engine coolant level no longer
drops.
8. Check cooling system for leaks with engine running.
9. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
10. Repeat step 9 three times.
11. If sound is heard, bleed air from cooling system by repeating steps 2 through 5 until engine coolant level
no longer drops.

reservoir tank with water and reinstall radiator cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water from the system. Refer to MA-28, "
DRAINING ENGINE COOLANT" .
6. Repeat steps 1 through 5 until clear water begins to drain from radiator.
Checking Cooling SystemELS000C4
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter
turn to allow built-up pressure to escape. Carefully remove the cap by turning it all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.

Be careful not to bend or damage the radiator fins.

When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downwards.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downwards.

Use compressed air lower than 490 kpa (4.9 bar, 5 kg/cm2 , 71psi) and keep distance more than 30
cm(11.8 in).
5. Blow air again into all the radiator core surface once per minute until no water sprays out.
CHECKING RADIATOR CAP
1. Pull negative-pressure valve to open it and make sure that it
closes completely when released.

Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.

Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

Aiming Adjustment for HeadlampEKS003CG
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 man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.

Keep all tires inflated to correct pressures.

Place vehicle and tester on one and same flat surface.

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).

2. Use adjusting screws to perform aiming adjustment.

First tighten the adjusting screw all the way and then make adjustment by loosening the screw.
If the vehicle front body has been repaired and/or the headlamp assembly has been replaced, check
aiming. Use the aiming chart shown in the figure.

Adjust headlamps so that main axis of light is parallel to cen-
ter line of body and is aligned with point P shown in illustra-
tion.

Figure to the right shows headlamp aiming pattern for driving
on right side of road; for driving on left side of road, aiming
pattern is reversed.

Dotted lines to point P in illustration show center of head-
lamp.

Basic illuminating area for adjustment should be within the
range shown at right. Adjust headlamps accordingly.
CAUTION:
Be sure aiming switch is set to “0” when preforming aiming
adjustment.
Aiming Adjustment for Driving LampEKS00AP6

Turn the aiming adjusting screw to adjust.

For positions of the adjustment screws and direction to turn,
refer to the figures.

When adjusting for right or left side, adjust upper and lower
adjustment screws at the same time.
PREPARATION BEFORE ADJUSTING
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1. Keep all tires inflated to correct pressures.
2. Place vehicle on level ground.
3. Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position),
