•  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.

Replace the oil filter, refer to 

3.2  Oil Filter

. 

8 

Lower the vehicle to the ground and fill with the specified amount of SAE 5W30 lubricant.

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

. 

13

Oil Filter Adaptor 

Remove 

 

Disconnection of the battery affects 

 

certain vehicle electronic systems, refer to  

1.1   WARNING, CAUTION and NOTES

 before 

disconnecting the battery. 

1 

Disconnect the battery negative terminal. 

2 

Disconnect the wiring harness connector from the oil pressure sender. 

 

 

3 

Remove the oil filter adaptor attaching bolts (2), four 
places. 

4 

Remove the oil filter adaptor and discard the gasket 
(3). 

5 

Clean the surfaces of the adaptor and cylinder block. 

 

•  Do not use a screwdriver or similar to 

prise the oil filter adapter from the engine 
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.
