1998 NISSAN MAXIMA spark plugs replace

6. Holding the ignition coil, re-connect each
ignition coil to its proper spark plug by
pushing it on until you feel a snap.
7. Tighten all ignition coils.
Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
Always replace with recommended
platinum-tipped spark plugs.

EXPLANATION OF MAINTENANCE
ITEMSAdditional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.Emission control system
maintenanceDrive belts*:Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter:Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines:Check EVAP vapor lines
and connections for failure or looseness. If
leaks are found, replace them.
Fuel lines:Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.Fuel filter:If the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are either
extremely low or extremely high, the filter
might become clogged. In such an event,
replace the filter immediately.
Engine coolant*:Drain and flush the cooling
system.
Engine oil & oil filter*:Under normal driving
conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*:Replace with new plugs having
the correct heat range.
Intake & exhaust valve clearance:Check the
valve clearance if valve noise increases.
Chassis and body maintenanceBrake lines & cables:Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.Brake pads & discs:Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
conditions, they may have to be inspected
more frequently.
Manual & automatic transaxle fluid*:Check
the fluid level and visually inspect for signs of
leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts, and drive shaft boots:Check for dam-
age, looseness and leakage of oil or grease.
Under severe driving conditions, more fre-
quent inspection should be performed.
Exhaust system:Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.
Supplemental air bag, and supplemental
side air bag (if so equipped) systems:Main-
tenance for the supplemental air bags or
supplemental side air bags should be done by
an authorized NISSAN dealer.
