Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Oil Pressure Test
If the oil pressure indicator stays on with the engine running, check the engine oil level. If the oil level is correct:
- Remove the engine oil pressure switch, and install an oil pressure gauge (A).
- 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: 176 °F (80 °C)
Engine Oil Pressure:
At Idle: 250 kPa (2.5 kgf/cm 2 , 36 psi) min.
At 3,000 RPM: 590 kPa (6.0 kgf/cm 2 , 85 psi) min.
- If oil pressure is out of specifications, inspect these items:
- Inspect the oil pressure relief valve (see OIL PUMP OVERHAUL ).
- Check the oil filter for clogging.
- Inspect the oil pump (see INSPECTION ).
