Engine Oil Pressure Test

1. Special Tools Required Oil pressure gauge attachment 07406-0030000 Oil pressure gauge 07506-3000001 If the oil pressure warning light stays on with the engine running, check the engine oil level. If the oil level is correct: Remove the oil pressure switch, and install the special tools. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
   Engine Oil Temperature: | 80 °C (176 °F)
   Engine Oil Pressure: |
   At Idle: | 70 kPa (0.7 kgf/cm 2 , 10 psi) min.
   At 3,000 rpm (min −1 ): | 300 kPa (3.1 kgf/cm 2 , 44 psi) min.
If the oil pressure is not within specifications, inspect these items: Check the oil screen for clogging. Check the oil pump. |
