Refill with new engine oil.
Engine oil specification and viscosity:

●

Refer to

Engine oil capacity (Approximate);

Unit:

(US qt, lmp qt)

CAUTION:

●

The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.

●

Always use the oil level gauge to determine when the proper amount of engine oil is in
engine.

Warm up engine and check area around drain plug and oil filter for oil leakage.

Stop engine and wait for 15 minutes.

10. Check engine oil level. Refer to

REMOVAL

Open oil filter installation/removal cover on engine undercover.

Using the oil filter wrench (SST), remove the oil filter.

CAUTION:

●

The oil filter is provided with a relief valve.
Use genuine NISSAN oil filter or equivalent.

●

Be careful not to get burned when engine and engine oil
are hot.

●

When removing, prepare a shop cloth to absorb any
engine oil leakage or spillage.

●

Do not allow engine oil to adhere to drive belts.

●

Completely wipe off any engine oil that adhere to engine
and vehicle.

INSTALLATION

Remove foreign materials adhering to the oil filter installation surface.

Apply engine oil to the oil seal circumference of new oil filter.

ENGINE MAINTENANCE

Screw oil filter manually until it touches the installation surface,
then tighten it by 2/3 turn. Or tighten to specification.

INSPECTION AFTER INSTALLATION

Start engine, and check there is no leak of engine oil.

Stop engine and wait for 15 minutes.

Check the engine oil level an add engine oil. Refer to

LU-6, "ENGINE OIL"

Changing Spark Plugs (Platinum-Tipped Type)

ELS000KX

REMOVAL

Remove engine cover with power tool. Refer to

EM-11, "ENGINE ROOM COVER"

Remove ignition coil. Refer to

EM-28, "IGNITION COIL"

Remove spark plug using the spark plug wrench (commercial
service tool).

INSPECTION AFTER REMOVAL

●

Use standard type spark plug for normal condition.

The hot type spark plug is suitable when fouling occurs with the standard type spark plug under conditions
such as:

●

Frequent engine starts

●

Low ambient temperatures

The cold type spark plug is suitable when spark plug knock occurs with the standard type spark plug under
conditions such as:

●

Extended highway driving

●

Frequent high engine revolution
Spark plug (Platinum-tipped type):

Oil filter:

:14.7 - 20.6 N·m (1.5 - 2.1 kg-m, 11 - 15 ft-lb)

CAUTION:

●

Do not drop or shock spark plug.

●

Do not use a wire brush for cleaning.

●

If plug tip is covered with carbon, spark plug cleaner may
be used.

●

Checking and adjusting plug gap is not required between
change intervals.

INSTALLATION

Install in the reverse order of removal.

Checking EVAP Vapor Lines

ELS000KY

Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.

Inspect fuel tank filler cap vacuum relief valve for clogging, sticking, etc.
Refer to

EC-684, "EVAPORATIVE EMISSION SYSTEM"

Checking Cooling Fan Fluid Level and Lines

ELS000KZ

●

Check that there is no fluid leaking from any hose connection or
any other part.

●

Check the fluid level with level gauge on reservoir tank cap. If
there is too much or too little, adjust the amount of fluid.

●

Check that under the fluid temperature conditions below, the
fluid level is within the “COLD” or “HOT” range on level gauge.

NOTE:

●

There is no specified timing for replacing the fluid.

●

The total fluid volume is 777 ml (26.3 US fl oz, 27.4 lmp fl oz) (with the cold maximum on level gauge
when engine is cold).

Cleaner air pressure:

Less than 588 kPa (6 kg/cm

, 85 psi)

Cleaning time:

Less than 20 seconds

SMA773C

Spark plug:

: 24.6 N·m (2.5 kg-m, 18 ft-lb)

COLD

: Fluid temperature 0 - 30

C (32 - 86

HOT

: Fluid temperature 50 - 80

C (122 - 176

Checking Exhaust System

ELS0001C

Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, chafing or deterioration.

●

If anything is found, repair or replace damaged parts.

Checking A/T Fluid

ELS0001G

Warm up engine.

Check for fluid leakage.

Remove the tightening bolt for A/T fluid level gauge.

Before driving, fluid level can be checked at fluid temperatures of 30 to 50

C (86 to 122

F) using “COLD”

range on A/T fluid level gauge as follows.

Park vehicle on level surface and set parking brake.

Start engine and move selector lever through each gear position. Leave selector lever in “P” position.

Check fluid level with engine idling.

Remove A/T fluid level gauge and wipe clean with lint-free paper.

CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.

Re-insert A/T fluid level gauge into charging pipe as far as it will go.

CAUTION:

To check fluid level, insert the A/T fluid level gauge until the cap contacts the end of the charging
pipe, with the gauge reversed from the normal attachment conditions.

Remove A/T fluid level gauge and note reading. If reading is at low side of range, add fluid to the charging
pipe.

CAUTION:

Do not overfill.

Drive vehicle for approximately 5 minutes in urban areas.

Make the fluid temperature approximately 65

C (149

F).
