Oil Pressure Check
- With the vehicle on a level surface, allow adequate drain down time, 2-3 minutes, and measure for a low engine oil level. Add the recommended grade engine oil, and fill the crankcase until the oil level measures FULL on the oil level indicator.
- Operate the engine and verify low or no oil pressure on the vehicle oil pressure gauge or the oil indicator light. Listen for a noisy valve train or a knocking noise.
- Inspect for the following :
- Remove the oil pressure switch from the oil filter adapter.
- Install the oil pressure gauge adapter and the oil pressure gauge at the place of the oil pressure switch.
- Start the engine and then allow the engine to reach normal operation temperature.
- Measure the engine oil pressure at idle speed.
- The minimum oil pressure should be 69 kPa (10.00 psi) at idle and 138 kpa (20.01 psi) at 2,000 rpm.
- If the engine oil pressure is below minimum specifications, inspect the engine for one or more of the following :
- After checking the oil pressure, remove the oil pressure gauge and adapter and then install the oil pressure switch to 13 N•m (115 lb-in).
- Check the oil level. Add oil until it reaches the MAX mark if needed.
