Engine Lubrication: Testing and Inspection
Oil Pressure CheckCaution: Be careful not to burn yourself, as the engine and oil may be hot.
1. Warm up engine.
2. Stop engine and remove oil pressure switch.
3. Install pressure gauge with sealant.
4. Start engine and check oil pressure with engine running under no-load.
Oil pressure at idling should be more than 78 kPa (0.8 kg/cm2 ,11 psi).
5. Install oil pressure switch.
Tighten: 13.17 N.m (1.3-1.7 kg-m,9-12 ft-lb)
The above image shows data tested when SAE 1OW-30 oil is used and oil temperature is between 77 and 83°C (171 and 181°F). Slight difference will be found because of oil viscosity or oil temperature. If difference is extreme, check oil passage and oil pump for oil leaks.
