Engine Oil PressureINSPECTION
1) Remove the oil pressure switch from engine cylinder block.
2) Connect the oil pressure gauge hose to cylinder block.
3) Connect the battery ground cable to battery.
4) Start the engine, and then measure the oil pressure.
Oil pressure: 98 kPa (1.0 kg/cm2, 14 psi) or more at 800 rpm 294 kPa (3.0 kg/cm2, 43 psi) or more at 5,000 rpm
CAUTION:
^ If the oil pressure is out of specification, check oil pump, oil filter and lubrication line.
^ If the oil pressure warning light is turned ON and oil pressure is in specification, replace the oil pressure switch.
NOTE: The specified data is based on an engine oil temperature of 80°C (176°F).
5) After measuring the oil pressure, install the oil pressure switch.
