ENGINE MAINTENANCE

INSPECTION AFTER REMOVAL

Use standard type spark plug for normal condition.

Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

●

Frequent engine starts

●

Low ambient temperatures

Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions 
such as:

●

Extended highway driving

●

Frequent high engine revolution

CAUTION:

●

Do not drop or shock spark plug.

●

Do not use 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

NLS0005S

1.

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

2.

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

EC-32, "EVAPORATIVE EMISSION SYSTEM"

Checking Exhaust System

NLS0001P

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 Clutch Fluid Level and Leaks

NLS0001Q

If fluid level is extremely low, check clutch system for leaks.

Checking M/T Oil Leakage

NLS0001R

●

Check if oil is leaking from transmission or around it.

CHASSIS AND BODY MAINTENANCE

Changing M/T Oil

NLS0001S

1.

Drain oil from drain plug and refill with new gear oil.

2.

Check oil level from filler hole as shown in the figure.

CAUTION:

Do not reuse gaskets.

Checking A/T Fluid

NLS0001T

1.

Warm up engine.

2.

Check for fluid leakage.

3.

Loosen the level gauge bolt.

4.

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.

a.

Park vehicle on level surface and set parking brake.

b.

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

c.

Check fluid level with engine idling.

d.

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.

e.

Re-insert A/T fluid level gauge into A/T fluid 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 A/T fluid
charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.

f.

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

CAUTION:

Do not overfill.

5.

Drive vehicle for approximately 5 minutes in urban areas.

6.

Make the fluid temperature approximately 65

°

C (149

°

F).

Oil grade and 
viscosity:

Refer to

NOTE:
Fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to per-
form operation while checking data with CONSULT-II.

a.

Connect CONSULT-II to data link connector.Refer to 

GI-37, "CONSULT-II Start Procedure"

 .

b.

Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.

c.

Read out the value of “ATF TEMP 1”.

7.

Recheck fluid level at fluid temperatures of approximately 65

°

C

(149

°

F) using “HOT” range on A/T fluid level gauge.

CAUTION:

●

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

●

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

8.

Check fluid condition.

●

If fluid is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.

●

If ATF contains frictional material (clutches, bands, etc.), replace radiator and flush cooler line using
cleaning solvent and compressed air after repair of A/T. Refer to 

CO-13, "RADIATOR"

  and 

AT-14, "A/T

Fluid Cooler Cleaning"

 .

9.

Install the removed A/T fluid level gauge in the A/T fluid charging
pipe.
