Changing Engine Oil

ALS00065

WARNING:

Be careful not to burn yourself, as engine oil is hot.

Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used engine oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible. 

1.

Remove engine undercover with power tool.

2.

Warm up engine, and check for engine oil leakage from engine
components.

3.

Stop engine and wait for 15 minutes.

4.

Loosen oil filler cap, then remove drain plug.

5.

Drain engine oil. 

6.

Install drain plug with new washer. Refer to 

EM-25, "OIL PAN AND OIL STRAINER"

 .

CAUTION:

Be sure to clean drain plug and install with new washer.

7.

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

MA-10, "RECOMMENDED FLUIDS AND LUBRICANTS"

 .

Engine oil capacity (Approximate):

                                                                                                                                                                  Unit: 

 (US qt, Imp 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.

8.

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

9.

Stop engine and wait for 15 minutes.

10. Check the engine oil level.

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):

CAUTION:

Do not drop or shock spark plug.

Do not use a wire brush for cleaning.

Checking EVAP Vapor Lines

ALS00020

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-692, "EVAPORATIVE EMISSION SYSTEM"

 .

Checking Cooling Fan Fluid Level and Lines

ALS00021

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

Check the fluid level with level gauge on the 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 the level
gauge. 

NOTE:

There is no specified timing for replacing the fluid.

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

Spark plug:

 : 24. 6 N·m (2.5 kg-m, 18 ft-lb)
