Attention! A hot engine and oil can cause severe burns. Before checking, stop the engine and wait until the engine and engine oil have cooled down.
Remove the lower engine cover.
Remove the oil pressure sensor.
Pic. 2.200. Installation of a special tool for measuring oil pressure
Screw the special tool into the oil pressure sensor hole (pic. 2.200).
Warm up the engine to normal operating temperature.
Set the specified engine speed and record the instrument readings.
If the pressure is not as specified, find the cause and repair or replace damaged parts as necessary.
Note. Oil pressure depends on viscosity and temperature.
Oil pressure
Oil temperature - 100°C:
- L8, LF: 234-521 kPa (2.39–5.31 kgf/cm2 at 3000 min–1);
- L3: 395–649 kPa (4.03–6.61 kgf/cm2 at 3000 min–1).
Stop the engine and let it cool down.
Remove the special tool.
Attention! If the sealing material gets on the working part of the oil pressure sensor, it can lead to the failure of the sensor. Make sure that there is no sealing material on the working part of the oil pressure sensor.
Pic. 2.201. The place where the sealant is applied to the threads of the oil pressure sensor
Apply silicone sealant to the threads of the oil pressure sensor, as shown in Figure 2.201.
Install the oil pressure sensor.
Tightening torque: 12–18 Nm.
Install the engine cover.
Start the engine and check for oil leakage. If there is a leak, identify the defective part and repair or replace it.
