Oil pressure, checking
The oil pressure warning switch is located at the base of the
oil filter housing.
In 6-cylinder engines access to oil pressure warning switch
connector (arrow) is extremely restricted (intake manifold re.
moved for the purpose of illustration).
V-8 engine oil pressure warning switch (arrow) is at base of
oil filter housing on left engine compartment inner fender.
Oil pressure is tested by removing oil pressure switch and in-
stalling oil pressure gauge in its place.
Unscrew oil filter cap in order to allow engine oil to drain back
down into oil pan.
Disconnect harness connector from oil pressure switch and
remove switch.
NOJE-
Thoroughly clean around the oil pressure switch before
removing it.
Be prepared to catch leaking oil with a shop towel.
- Install pressure gauge in place of oil pressure switch,
- With gauge installed, start engine and allow to reach operat-
ing temperature. Check oil pressure. See Table b.
NOJE-
For the most accurate test results, the engine oil and filter
should be new. The oil should be the correct grade.
Table b. Engine oil pressure
At idle 0.5 bar (7 psi)
At elevated speed
6-cylinder engine 4.0 bar
(59 psi)
V-8 engine 4.5 bar (66 psi)

- Remove pressure gauge and reinstall pressure switch with
new sealing washer.
Tightening torque
Oil pressure switch to oil filter housing 27 Nm (20 ft-lb)
If testing shows low oil pressure, one or more of the following
conditions may be indicated:
Worn or faulty oil pump or faulty pump pressure relief valve
Worn or damaged engine bearings
Severe engine wear
Any of these conditions indicate the need for major repairs.
Oil pressure warning system, testing
4 When the ignition is turned on, the oil pressure warning light
comes on. When the engine is started and the oil pressure
rises slightly, the oil pressure switch (arrow) contact opens
and the warning light goes out. Make sure the oil level is cor-
rect before making tests.
- Turn ignition switch on.
- Warning light on instrument panel must light up
- Remove connector from oil pressure switch.
Warning light on instrument panel must go out.
NOTE-
If the light does not go out, the wiring to the switch is most
likely grounded somewhere between the switch terminaland
the warning light See
ELE Electrical Wiring Diagrams for
electrical schematics.
- If warning light does not light when ignition is on, remove con-
nector from oil pressure switch and use a jumper wire to
ground connector terminal to a clean metal surface. The oil
pressure warning light should come on.
NOTE-
If there are two wires to the oil pressure switch, ground the
brown/green wire that carries the signal to the warning light.
- If the warning light comes on, check the switch as described
in the next step. If the warning light does not come on, the
wiring to the instrument cluster or to the light itself is faulty.

- Remove power steering pump, leaving hydraulic lines con-
nected to pump. Suspend pump using strong wire. See

< Disconnect electrical harness connector (arrow) at oil level
sensor.
< Remove lower oil pan mounting bolts (arrows)
CAUTIOI\C
If the lowerpan does not separate easily from upperpan, a
few taps with a rubber mallet should break it free. Do
notpry
the oil pan loose.
- When installing oil pan:
Thoroughly clean all old
gasltet material from mating sur-
faces and use a new gasket.
4 Install threaded guide studs at locations marked by arrows
to guide new oil pan
gasltet and oil pan into position and to
prevent damage to sealing lip.
- Install new oil pan mounting bolts (threads coated with
sealer).
Remove guide studs and install remainder of oil pan bolts.
- Remainder of reassembly is reverse of disassembly
- After adding engine oil, start and run engine. Raise engine
speed to 2,500 rpm until oil pressure warning light goes out
(about 5 seconds).
