1999 NISSAN QUEST spark plugs replace

JUMP STARTING
If jump starting is necessary, see the ``In
case of emergency'' section. If the engine
does not start by jump starting, the battery
may have to be replaced. Contact an autho-
rized NISSAN dealer.
WARNING
Be sure the ignition key is OFF. The
engine could rotate unexpectedly.
1. Visually inspect each belt for signs of
unusual wear, cuts, fraying or looseness.
If the belt is loose or in poor condition,
have it replaced or adjusted by an autho-
rized NISSAN dealer.
2. Have the belts checked regularly for con-
dition and tension in accordance with the
maintenance schedule found in the
``Maintenance'' section of this manual.WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.

Platinum-tipped spark plug
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. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the boots,
not the cables.2. Remove the spark plugs with a spark
plug socket. The plug socket has a rub-
ber 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 plug socket.
3. 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)
4. Holding the boot, re-connect each high
tension cable to its proper spark plug by
pushing it on until you feel a snap.The filter should not be cleaned and reused.
Replace it according to the maintenance
intervals shown in the ``Maintenance'' sec-
tion of this manual. When replacing the
filter, unclip the four clamps and remove the
filter. Wipe the inside of the air cleaner
housing and the cover with a damp cloth
when replacing filter.

Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself operations'' section of this
manual.
Emission control system
maintenance
Drive belts* ÐCheck drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Engine air cleaner filter ÐUnder normal
driving conditions, the air cleaner filter should
be replaced in accordance with the mainte-
nance schedule. However, driving the vehicle
in dusty areas may cause rapid clogging of
the element. Consequently, the element may
have to be replaced more frequently.
Evap vapor lines ÐCheck vapor lines and
connections for leaks, looseness or deterio-
ration. If leaks are found, replace them.
Fuel lines ÐCheck the fuel hoses, piping
and connections for leaks, looseness or
deterioration. Replace any damaged parts.
Fuel filter ÐIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, thefilter might become clogged. In such an
event, replace the filter immediately.
Engine coolant* ÐChanging engine cool-
ant can be performed by your NISSAN
dealer or procedures can be found in the
Service Manual. Improper air relief after
changing coolant can result in reduced
heater performance and overheating.
Engine oil & oil filter* ÐUnder normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs* ÐReplace with new plugs
having the correct heat range.
Timing belt ÐReplace the timing belt for
driving the camshaft.
Chassis and body maintenance
Brake lines & cables ÐCheck the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.Brake pads, rotors, drums & linings Ð
Check these and the other brake compo-
nents for wear, deterioration and leaks. Un-
der severe driving conditions, they may
have to be inspected more frequently.
Automatic transmission fluid* ÐCheck
the fluid level and visually inspect for signs
of leakage.
Under severe driving conditions, the fluid
should be replaced at the specified interval.
Steering gear & linkage, axle & suspen-
sion parts, and drive shaft boots ÐCheck
for damage, looseness and leakage of oil or
grease. Under severe driving conditions, they
may have to be inspected more frequently.
Exhaust system ÐVisually check the ex-
haust pipes, muffler, and hangers for proper
attachment, leaks, cracks, chafing, abra-
sion, deterioration, etc. Under severe driv-
ing conditions, inspection should be per-
formed more frequently.
Supplemental air bag system ÐCheck
the supplemental air bag system compo-
nents for proper attachment, damage, de-
formities, cracks, rust, etc. Work around and
on the supplemental air bag system should
be done by an authorized NISSAN dealer.
