Replace

N O T E

• Quicker and more complete draining will

occur if the engine oil is at normal operating
temperature. However, care must be taken to
avoid scalding from the hot oil.

• It recommended the oil filter be changed at

each engine oil change, refer to

3.2 Oil Filter

.

1

Remove the oil fill cap.

2

To ensure complete draining of the oil pan, raise the front and rear of the vehicle to maintain a level attitude. If not
using a hoist, support the vehicle with safety stands, refer to

Section 0A General Information

.

3

Clean any foreign material from around the oil drain plug and place a suitable, clean drain tray under the engine.

The oil may be hot. Avoid contact with the oil.
Ensure that eyes and skin are protected.

4

Remove the drain plug (1), taking care to avoid scalding from the hot oil. Allow the oil to drain.

5

Clean and inspect the drain plug threads. If damaged, replace the drain plug.

Figure 6A1 – 24

Pressure Check

1

Run the engine to bring it to normal operating temperature.

2

Park the vehicle on a level surface. A vehicle not level will affect the accuracy of the level reading.

3

Stop the engine and wait 5 to 10 minutes to allow the oil to drain back into the oil pan.

4

Check the oil level and top up with the recommended engine oil as required, refer to Check, in this Section.

5

Remove the engine oil pressure sensor (1), refer to

Section 6C1-3 Engine Management – V6 – Service
Operations

.

6

Install the oil pressure gauge adaptor, Tool No.
J36648-A into the oil pressure sender hole in the oil
filter housing.

7

Install a suitable oil pressure gauge into the adaptor.

8

Start the engine.

9

Measure and record the pressure reading on the
gauge at idle and 2000 r.p.m. Compare the results
with the specification.

Minimum engine oil pressure
@ idle. . . . . . . . . . . . . . . . ... 69 kPa

@ 2000 r.p.m. . . . . . . . . . . . . . 138 kPa

10

If the engine oil pressure is not to specification, refer to

2.19 Engine Oil Pressure Diagnosis

.

11

After completing the engine oil pressure check, stop
the engine and remove the oil pressure gauge.

Figure 6A1 – 25

12

Reinstall the oil pressure sensor, refer to

Section 6C1-3 Engine Management – V6 – Service Operations

as damage to the sealing surface may
occur.

• If required, use a rubber mallet to tap the

oil filter adapter to loosen the
components prior to separating.
Tapping should be done at bends,
corners or reinforced areas to prevent
distortion of parts.
