(1) Remove the oil pan. (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - REMOVAL)
(2) Remove the pressure relief valve by remove the
threaded retaining cap from the oil pump housing.
CAUTION: Oil pump pressure relief valve must be
installed as shown in (Fig. 97) or engine damage
may occur.
(3) Remove spring and relief valve (Fig. 97).
INSTALLATION
(1) Lubricate relief valve with oil.
CAUTION:
The
pressure
relief
valve
must
be
installed as shown in (Fig. 97), or engine damage
may occur.
(2) Install relief valve, spring and retainer cap
(Fig. 97). Tighten cap to 12 N·m (105 in. lbs.).
(3) Install the oil pan. (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - INSTALLATION)
OIL PRESSURE SWITCH
DESCRIPTION
The engine oil pressure switch is located on the
right side of the engine block. The switch screws into
the engine main oil gallery. The normally closed
switch provides an input through a single wire to the
low pressure indicator light on the instrument clus-
ter.
REMOVAL
(1) Raise vehicle on hoist.
(2) Remove heat shield that covers oil pressure
switch.
(3) Disconnect oil pressure switch electrical con-
nector.
(4) Position
an
oil
collecting
container
under
switch location.
(5) Remove switch by unscrewing from the engine
block.
INSTALLATION
(1) Apply Mopar
t Thread Sealant to the switch
threads.
(2) Install oil pressure switch.
(3) Connect electrical connector.
(4) Install oil pressure switch heat shield.
(5) Lower vehicle.
(6) Start engine and check for leaks.
(7) Check engine oil level and adjust as neccessary.
OIL PUMP
REMOVAL
The oil pump pressure relief valve can be serviced
by removing the oil pan.
