Warning

• Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your

skin by washing with soap and water immediately after working with engine oil.

• Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the

engine oil have cooled.

1. Remove the under cover.
2. Remove the oil pressure switch.
3. Screw the SST into the oil pressure switch

installation hole.

4. Warm up the engine to normal operating

temperature.

5. Run the engine at the specified speed, and note

the gauge readings.

• If the pressure is not as specified, inspect for

the cause and repair or replace as necessary.

Note

• The oil pressure can vary with oil viscosity

and temperature.

Oil pressure [Oil temperature: 100

°C{212°F}]:

L8, LF :

234—521 kPa {2.39—5.31 kgf/cm

2

,33.9—

75.5 psi} min. [ 3,000rpm]

L3 :

395—649 kPa {4.03—6.61 kgf/cm

2

, 57.3—

94.1 psi} min. [ 3,000rpm]

6. Stop the engine and wait until it is cool.
7. Remove the SST.

Caution

• Any sealant stuck at the end of the oil pressure switch can cause operation malfunction of the oil

pressure switch.
Be sure there is no sealant at the end of the oil pressure switch.

8. Apply silicone sealant to the oil pressure switch

threads as shown.

9. Install the oil pressure switch.

Tightening torque:

12—18 N·m {1.2—1.8 kgf·m, 9—13 ft·lbf}

10. Install the under cover.
11. Start the engine and inspect for oil leakage.

• If the oil leaks, specify the faulty part and

Warning

• Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the

engine oil has cooled.

• A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall,

causing death or serious injury. Never work around or under a lifted vehicle if it is not securely
supported on safety stands.

• Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your

skin by washing with soap and water immediately after working with engine oil.

Caution

• In case you spill engine oil on the front pipe, wipe it off completely. If you fail to wipe the spilled

oil, it will produce a white smoke because of the heat.

1. Position the vehicle on level ground.
2. Remove the oil filler cap .
3. Remove the under cover.
4. Remove the oil pan drain plug.
5. Drain the engine oil into a container.

6. Install the oil pan drain plug.

• With washer

1. Install the oil pan drain plug with a new washer.

Tightening torque

30—41 N·m {3.1—4.1 kgf·m, 23—30 ft·lbf}

• Without washer

1. Inspect the seal rubber of the oil pan drain plug and make sure there are no cracks or damage.

— If necessary, replace the oil pan drain plug.

2. Clean the flange surface (seal rubber) on the oil pan drain plug, then install the oil pan drain plug.

Tightening torque

22—30 N·m {2.2—3.1 kgf·m, 16—22 ft·lbf}

Note

• The amount of residual oil in the engine can vary according to the replacement method, oil temperature, etc.

Verify the oil level after engine oil replacement.

7. Refill the engine with the specified type and amount of engine oil.

Oil capacity (Approximate quantity)

L {US qt, Imp qt}

*

: Always verify the oil level with the dipsticks since the engine oil capacity differs according to dipstick

specifications.
