2000 NISSAN FRONTIER boot

1. Disconnect the spark plug cables.
When disconnecting, always hold the
boots Ð not the cables. Mark all cables
to identify their original location.
2. Remove the spark plugs with a spark
plug socket.
3. Fit the new spark 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 over-
tighten.Spark plug tightening torque:
14 to 22 ft-lb (20 to 29 N×m)
4. Reconnect the spark plug cables to their
original positions.

EXPLANATION OF
MAINTENANCE ITEMS
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Emission control system
maintenance
Drive belts*Check drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Air cleaner filterUnder normal driving con-
ditions, the air cleaner filter should be re-
placed in accordance with the maintenance
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.
Positive crankcase ventilation (PCV) fil-
terUnder normal driving conditions, the
filter should be replaced in accordance with
the maintenance schedule. If the vehicle is
operated under extremely adverse weather
conditions or in areas where ambient tem-
peratures are either extremely low or ex-
tremely high, the filter may become cloggedmore rapidly. In such an event, replace the
filter immediately.
EVAP Vapor linesCheck vapor lines and
connections for leaks, looseness, or dete-
rioration. If leaks are found, replace the
lines.
Fuel lines (hoses, piping, connections,
etc.)Check the fuel hoses, piping and con-
nections for leaks, looseness or deteriora-
tion. Replace any damaged parts.
Fuel filterIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, the
filter might become clogged. In such an
event, replace the filter immediately.
Engine coolant*Flush and refill the cooling
system.
Engine oil and oil filter*Under 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*Replace with new plugs hav-
ing the correct heat range.
Chassis and body maintenance
Brake lines and cablesCheck 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 and linings
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.
Manual and automatic transmission,
transfer and differential gear oilVisually
inspect for signs of leakage and replace oil
for limited-slip differential. Under severe
driving conditions, the oil should be re-
placed at the specified interval.
Steering gear (box) and linkage, axle and
suspension parts and drive shaft boots
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, they may have to be inspected more
frequently.
