Engine Oil Pressure Test
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:

| 2. | Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
|
| 3. | 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/cm2, 10 psi) minimum | | At 3,000 rpm (min-1): | 300 kPa (3.1 kgf/cm2, 44 psi) minimum |
|
| 4. | If the oil pressure is NOT within specifications, inspect these items:
