CAUTION: Do not operate engine if the oil level is
above the MAX mark on the dipstick. Excessive oil
volume can cause oil aeration which can lead to
engine failure due to loss of oil pressure or
increase in oil temperature.

OIL PRESSURE SENSOR/
SWITCH
DESCRIPTION
The oil pressure switch is located on the right rear
side of the engine block (Fig. 103). The oil pressure
switch is a pressure sensitive switch that is activated
by the engine’s oil pressure (in the main oil gallery).
The switch is a two terminal device (one terminal is
provided to the wiring harness and the other termi-
nal is the switch’s metal housing that screws into the
engine block).
OPERATION
The oil pressure switch is normally “Closed.” The
switch changes from a
9Closed9 circuit to an 9Open9
circuit, on increasing pressure of 7 psig. The oil pres-
sure switch changes from an
9Open9 circuit to a
9Closed9 circuit, on decreasing pressure, between 2
psig and 4 psig.
REMOVAL
(1) Raise vehicle.
(2) Position oil collecting container under pressure
switch location.
(3) Disconnect oil pressure switch electrical con-
nector and remove switch (Fig. 104).
INSTALLATION
(1) Install oil pressure switch and connect electri-
cal connector (Fig. 104).
(2) Lower vehicle.
(3) Start engine and allow to run a minimum of 2
minutes.
(4) Shut engine off and check engine oil level.
Adjust level as necessary.
OIL PUMP
