Oil Pressure
Testing
lf the oil pressure warning light stays on with the engine
running, check the engine oil level. It the oil level is
correct:
Connect a tachometer.
Remove the oil pressure switch and install an oil pres
s u r e g a u g e .
Start the engine. Shut it off immediately if the gauge
regasters no oil pressure. Repair the problem before
c o n t i n u i n g .
Allow the engine to reach operating temperature (fan
comes on at least twicel. The pressure should be:
Engine Oil Pressure:
At ldle:
70 kPa {O.7 kgficmr, tO psil
minimum
At 3,OOO rpm: 34O kPa (3.5 kgf/cmr, 50 psil
minimum
a lf oilpressure is within specifications, replace the
engine oil pressure switch and recheck.
