Engine Oil Pressure Test

Special Tools Required
Oil pressure gauge attachment (  07406-0030000)
 

Oil pressure gauge (  07506-3000001)
 


If the oil pressure warning light stays on with the engine running, check the engine oil level. If the oil level is correct:

1.Remove the engine oil pressure switch, and install the special tools.

 

2.Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.

3.Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:

Engine Oil Temperature: 80 °C (176 °F) 
Engine Oil Pressure  
At 820 rpm (min-1): 110 kPa (1.1 kgf/cm2, 16 psi) min. 
At 3,000 rpm (min-1): 410 kPa (4.2 kgf/cm2, 59 psi) min. 

4.If the oil pressure is without specifications, inspect these items:
