3. INSPECTION AND ADJUSTMENT

3.1 CHECKING ENGINE OIL CONSUMPTION

Engine oil consumption relates to the engine oil 
used during combustion in the engine. Since 
engine oil consumption is affected by driving style 
and the use to which the vehicle is put, it is also 
related to average fuel consumption. See 
"Technical data" for the maximum permissible 
engine oil consumption.

Test conditions
1.

An engine oil consumption test is only 
meaningful after the engine has been run in 
(approx. 25,000 km).

2.

Check the engine carefully for engine oil 
leakage before carrying out an engine oil 
consumption test. First repair any leaks.

3.

Check the average fuel consumption and 
engine oil consumption as accurately as 
possible.

4.

Only check the engine oil level when the 
engine is at operating temperature and only 
when the engine has been turned off for five 
minutes.

5.

Make sure the vehicle is horizontal before 
checking the engine oil level.

3.2 INSPECTION, LUBRICATING OIL PRESSURE

1.

Bring the engine up to operating 
temperature.

2.

Remove the plug from the main oil channel. 
It is located on the left, in the centre of the 
engine block.

3.

Connect the special tool  (DAF no. 0535551) 
to the oil pressure gauge connection.

4.

Start the engine and measure the lubricating 
oil pressure at idling speed and at full-load 
engine speed.
Compare the pressure readings with the 
technical data. See "Technical data".

5.

Stop the engine and remove the oil pressure 
gauge. Fit the plug with a new sealing ring.

3.3 PRESSURE TESTING THE OIL COOLER

1.

Remove the oil cooler. See "Removal and 
installation".

2.

Fit the special tool  (DAF no. 1329478).

3.

Apply up to 5 bar of pressurised air to the 
special tool.

4.

Immerse the oil cooler in warm water 
(approx. 50

|C) and check the cooling 

element for leaks.

Note:
The oil cooler should be replaced if it is 
leaking.

5.

Remove the special tool.

6.

Fit the oil cooler. See "Removal and 
Installation".
