Engine Oil Pressure Checking Procedure

1. Place the vehicle on a two-post lift.

2. Disconnect the negative battery terminal.

3. Loosen the mounting bolts and remove the engine protective pan.

4. D4F engine: loosen the bolts (1) and remove the heat shield (2).

8. Start the engine.

9. Monitor the engine oil pressure with the engine idling at operating temperature (80°C or when the radiator fan first operates).



10. If the oil pressure is below normal, make sure that the oil filter is not clogged and that there is no dirt or small sawdust in the engine oil. Check the condition of the oil pump.

11. Check oil pressure at 3000 rpm.
