OIL PRESSURE INSPECTION[L3 WITH TC]

id011139800300

Warning

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

engine oil have 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.

1. Disconnect the negative battery cable.
2. Remove the under cover.
3. Remove the oil pressure switch.
4. Screw the SSTs into the oil pressure switch

installation hole.

5. Connect the negative battery cable.
6. Warm up the engine to normal operating

temperature.

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

the gauge readings.

• If not within the specification, inspect for the

cause and repair or replace if necessary.

Note

• The oil pressure can vary with oil viscosity

and temperature.

Oil pressure (reference value) [oil temperature: 100

°C {212 °F}]

297— 551 kPa {3.03— 5.61 kgf/cm

2

, 43.1— 79.9 psi} [3,000 rpm]

8. Stop the engine and wait until it is cool.
9. Disconnect the negative battery cable.

10. Remove the SSTs.

Caution

• Make sure that there is no sealant between 1.0— 2.0 mm {0.04— 0.07 in} from the end of the oil

pressure switch to prevent a possible operation malfunction.

11. Apply silicone sealant to the oil pressure switch

threads as shown in the figure.

12. Install the oil pressure switch.

Tightening torque

12— 18 N·m {1.3— 1.8 kgf·m, 9— 13 ft·lbf}

13. Connect the negative battery cable.
14. Start the engine and confirm that there is no oil

leakage.

• If there is oil leakage, repair or replace the

applicable part.

15. Install the under cover.

1. Position the vehicle on level ground.
2. Warm up the engine.
3. Stop the engine and allow approx. 5 min before continuing.
4. Rotate the service hole cap (installed to charge

air cooler duct) used to remove/install the dipstick
in the direction shown in the figure and remove it.

5. Remove the dipstick and verify that the oil level is

between the MIN and MAX marks on the dipstick.

• If the oil level is below the MIN mark, add

engine oil.

6. Install the service hole cap by rotating it in the

direction shown in the figure.

Warning

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

engine oil have 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

• If engine oil is spilled on the exhaust system, wipe it off completely. If you fail to wipe the spilled

engine oil, it will produce fumes because of the heat.

1. Position the vehicle on level ground.
2. Remove the oil filler cap.
3. Remove the service hole cover (installed to under

cover) used to drain the engine oil.

4. Remove the oil pan drain plug.
5. Drain the engine oil into a container.
6. Install the oil pan drain plug with a new washer.

Oil pan drain plug tightening torque

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

Note

• The amount of residual oil in the engine can

vary according to factors such as the
replacement method and oil temperature.
Verify the oil level after engine oil
replacement.

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

Engine oil capacity (approx. quantity)

Oil replacement: 5.3 L {5.6 US qt, 4.7 Imp qt}
Oil and oil filter replacement: 5.7 L {6.0 US qt, 5.0 Imp qt}
Total (dry engine): 6.4 L {6.8 US qt, 5.6 Imp qt}

Engine oil specification

8. Install the oil filler cap.
9. Start the engine and confirm that there is no oil leakage.

• If there is oil leakage, repair or replace the applicable part.

10. Inspect the oil level. (See 01-11-3 ENGINE OIL LEVEL INSPECTION[L3 WITH TC].)
11. Install the service hole cover.
