9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
MAX level.
10. For QG18DE engine only, open and
close the air release plug(s) to release
air. Then fill the radiator again and install
the radiator cap.
11. Check the drain plugs on the radiator
and the engine block for any sign of
leakage. For QG18DE only, also check
the air release plug for any sign of
leakage.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.3. Turn off the engine.Wait a few minutes
for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.
5. Remove the dipstick again and check the
oil level. It should be between the H
(High) and L (Low) marks. If the oil level
is below the L (Low) mark, remove the oil
filler cap and pour recommended oil
through the opening.Do not overfill.

6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not cov-
ered by warranty.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature, and then turn it off.
3. Remove the oil filler cap.
4. Place a large drain pan under the drain
plug.
5. Remove the drain plug with a wrench and
completely drain the oil.If the oil filter is to be changed, remove
and replace it at this time. See ``Chang-
ing engine oil filter'' later in this section.
CAUTION
Be careful not to burn yourself. The
engine oil may be hot.
cWaste oil must be disposed of prop-
erly.
cCheck your local regulations.

6. Clean and reinstall the drain plug and a
new washer. Securely tighten the drain
plug with a wrench.
Drain plug tightening torque:
22 to 29 ft-lb (29 to 39 Nzm)
Do not overtighten.
7. Refill engine with recommended oil
through the oil filler opening then install
the oil filler cap securely.
See the ``Technical and consumer infor-
mation'' section for drain and refill capac-
ity.
The drain and refill capacity depends on
the oil temperature and drain time. Use
these specifications for reference only.
Always use the dipstick to determine
when the proper amount of oil is in the
engine.
8. Start the engine. Check for leakage
around the drain plug and oil filter. Cor-
rect as required.
9. Turn the engine off and wait several
minutes. Check the oil level with the
dipstick. Add engine oil if necessary.WARNING
cProlonged and repeated contact with
used engine oil may cause skin can-
cer.
cTry to avoid direct skin contact with
used oil. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
cKeep used engine oil out of reach of
children.
CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Place a large drain pan under the oil
filter.
4. Loosen the oil filter with an oil filter
wrench. Then remove the oil filter by
turning it by hand.
CAUTION
Be careful not to burn yourself. The
engine oil may be hot.

5. Wipe the engine oil filter mounting sur-
face with a clean rag.
Be sure to remove any old gasket mate-
rial remaining on the mounting surface of
the engine.
6. Coat the gasket on the new filter with
clean engine oil.
7. Screw on the oil filter until a slight resis-
tance is felt, then tighten an additional
2/3 turn.
8. Start the engine and check for leakage
around the oil filter. Correct as required.9. Turn the engine off and wait several
minutes. Check the oil level. Add engine
oil if necessary.WARNING
cWhen the engine is running, keep
hands, jewelry and clothing away
from any moving parts such as the
cooling fan and drive belts.
cAutomatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.

WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because they last
much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.1. On the 1.8L engine, disconnect the igni-
tion coil connectors. Remove the ignition
coil bolts.
2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.
3. Remove the spark plugs with a spark
plug socket.
The plug socket has a rubber seal that
holds the spark plug so it does not fall
when it is pulled out. Make sure each
spark plug is snugly fitted into the spark
plug socket.
4. Fit the new plugs, one at a time, into the
spark plug socket and install them.Use
only the specified spark plugs.Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb (20 to 29 Nzm)

5. Holding the boot, reconnect each high
tension cable to its proper spark plug by
pushing it on until you feel a snap.
6. On the 1.8L engine, install the ignition
coil bolt.
Ignition coil bolt tightening torque:
33 to 44 in-lb (3.8 - 5.0 Nzm)
Connect the ignition coil connector.
The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance intervals shown in the
``NISSAN Service and Maintenance Guide''.
When replacing the filter, wipe the inside of
the air cleaner housing and the cover with a
damp cloth.
WARNING
cOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops theflame if the engine backfires. If it
isn't there, and the engine backfires,
you could be burned. Do not drive
with the air cleaner removed and be
careful when working on the engine
with the air cleaner removed.
cNever pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
CABIN AIR FILTER (if so
equipped)
The cabin air filter restricts the entry of
airborne dust and pollen particles and re-
duces some objectionable outside odors.
The filter is located behind the glove box.
Refer to the ``NISSAN Service and Mainte-
nance Guide'' for change intervals.
To replace the filter, perform the following
procedure:

Before performing aiming adjustment, make
sure of the following:
a. Use an aiming wall screen.
b. Keep all of the tires inflated to the correct
pressure.
c. Place the vehicle and screen on level
ground.
d. See that the vehicle is unloaded (except
for full levels of coolant, engine oil and
fuel, and that the spare tire, jack, and
tools are stored). Have the driver or anequivalent weight placed in the driver's
seat.
1. Open the hood. Turn headlight low beam
on.
2. Adjust the vertical aim by turning the
adjustment screw.
cCover the opposite light and ensure the
fog lights (if so equipped) are turned off.
cAdjust beam pattern until cutoff line is
positioned at the same height off ground
as bulb center (on H-line).
