Oil Pressure Inspection
WARNING: This page is about a different car, the 2005 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.
- Hot engines and engine oil are hot, they can cause burns. Turn off the engine and wait until it and engine oil have cooled.
- Remove the oil pressure switch.
- Screw the SST into the oil pressure switch installation hole.
- Warm up the engine to normal operating temperature.
- Run the engine at the specified speed, and note the gauge readings.
- If the pressure is not within the specification, inspect amount of engine oil, and inspect for oil leakage or any wear parts inside of engine and so on. Repair or replace if necessary.
NOTE:- The oil pressure can vary with oil viscosity and temperature.
Oil pressure (approx. quantity)
- 295-392 kPa {3.0-4.0 kgf/cm2, 43-56 psi} [3,000 RPM]
- Stop the engine and wait until it is cool.
- Remove the SST. CAUTION:
- Do not apply liquid gasket to the tip of the oil pressure switch by 1.0-2.0 mm {0.4-0.7 in}.
- Apply silicone sealant to the oil pressure switch threads as shown in the figure.
- Install the oil pressure switch.
Tightening torque
- 12-17 N.m {1.2-1.8 kgf.m, 9-13 ft.lbf}
- Start the engine and inspect for oil leakage.
