Engine Oil Pressure Test

Special Tools Required
Pressure gauge attachment, PT 1/8
07406-0030000
Oil pressure gauge set
07506-3000001
NOTE: If the oil pressure warning light stays on with the engine running, check the engine oil level. If the oil level is correct:

1. Remove the engine oil pressure switch, and install the pressure gauge attachment (A) and the oil pressure gauge (B).

1. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.

1. 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.

1. If the oil pressure is out of specifications, inspect these items:
   - Replace the oil filter.
   - Inspect the oil pressure relief valve.
   - Check the oil screen for clogging.
   - Check the oil pump.
