3. Check each new spark plug gap with a
feeler gauge. Correct it as required.
4. Install spark plugs.
When installing a plug, turn it in two or
three turns by hand and then tighten with a
spark plug wrench. Be careful not to over-
tighten it.
Tightening torque:
14 to 22 ft-lb (20 to 29 N×m)
5. Reconnect the spark plug cables to their
original positions.The filter element should not be cleaned and
reused as it is given a special treatment. We
recommended it be replaced according to the
maintenance intervals. See ªPeriodic mainte-
nanceº in the ª9. Maintenanceº section for
maintenance intervals. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
IOperating the engine with the air
cleaner off can cause you or others to
be burned. The air cleaner not only

maintenanceAdditional information on the following
items with * is found in the ª8. Do-it-
yourselfº section.
Drive belts*:
Check drive belts for wear, fraying or cracking
and also for proper tension. Replace the drive
belts if found damaged.
Air filter:
Under normal driving conditions, 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. Conse-
quently, the element may have to be replaced
more frequently.
EVAP vapor lines:
Check vapor lines and connections for failure
or looseness. If leaks are found, replace the
lines.
Fuel lines:
Check the fuel hoses, piping and connections
for leaks, looseness or deterioration. 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*:
Flush and refill the cooling system.
Engine oil & oil filter*:
Under normal driving conditions, the engine oil
and oil filter should be replaced in accordance
with the maintenance schedule. However, un-
der severe driving conditions, they may have
to be replaced more frequently.
Spark plugs*:
Replace with new plugs having the correct
heat range.
Timing belt:
Replace the timing belt for driving the cam-
shafts.
Chassis and body maintenanceBrake lines & cables:
Check the brake lines and hoses (including
brake booster vacuum hoses, connections &
check valve) and parking brake cables for
proper attachment, leaks, cracks, chafing,
abrasion, deterioration, etc.
Brake pads, rotors, drums & linings:
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 and automatic transmission,
transfer & differential gear fluid:
Visually inspect for signs of leakage and re-
place oil for limited-slip differential. Under se-
vere driving conditions, the oil should be re-
placed at the specified interval.
Steering gear, linkage & transfer gear,
axle & suspension parts & drive axle
shaft boots:
Check for damage, looseness and leakage of
oil or grease. Under severe driving conditions,
more frequent inspection should be per-
formed.
