1. Connect a tachometer.
2. Remove the oil pressure switch and replace it with an oil pressure gauge.
1. hole for the engine oil pressure sensor
2. oil pressure gauge, 07506-3000000
3. adapter for oil pressure gauge. 07406-0030000
3. Start the engine. If the gauge does not show any oil pressure, stop the engine immediately. Troubleshoot before continuing.
4. Let the engine warm up to normal operating temperature (the fan will turn on at least two times). The pressure must be:
Engine oil temperature: 80°C.
Engine oil pressure:
At the speed of x.x. | 70 kPa (0.7 kgf/cm2) min. |
At 3000 rpm | 340 kPa (3.5 kgf/cm2) min. |
If the oil pressure is out of specification, check the oil pump (see below).
