Oil Pressure Inspection

NOTE:

If the oil pressure indicator light remains on a few seconds, check the indicator system before checking the oil pressure.

Check the oil level (page 3-13).

Warm up the engine to normal operating temperature (approximately 176°F/80°C). Stop the engine and disconnect the oil pressure switch wire connector from the switch.

Remove the oil pressure switch and connect an oil pressure gauge and attachment to the switch hole.

TOOLS:

Oil pressure gauge 07506 3000000

(Equivalent commercially available in U.S.A.) Oil pressure gauge attachment 07510 4220100

(Equivalent commercially available in U.S.A.)

Start the engine and increase the rpm to 5,400 rpm and read the oil pressure.

OIL PRESSURE:

490 kPa (5.0 kgf/cm2 ,71 psi) at 5,400 rpm (176°F/ 80°C)

Stop the engine and remove the tools.

Apply sealant to the threads of the oil pressure switch.

Do not apply sealant to the thread head. 3 4 mm (0.1 0.2 in)

Install and tighten it to the specified torque. TORQUE: 12 N m (1.2 kgf m , 9 Ibf ft)
