Chrysler New Yorker. Manual — part 275
CAUTION: Do not use automatic transmission fluid
in power steering system. Only use Mopar Power
Steering Fluid, or equivalent.
(5) Fill the power steering pump reservoir to cor-
rect fluid level.
(6) Start engine and turn steering wheel several
times from stop to stop to bleed air from fluid in sys-
tem. Stop engine, check fluid level, and inspect sys-
tem for leaks. See Checking Fluid Level.
DISASSEMBLY AND ASSEMBLY
POWER STEERING FLUID RESERVOIR (2.7L
ENGINE)
REMOVE
The 2.7 liter engine uses a power steering fluid
reservoir that is integral to the power steering pump.
To replace the power steering fluid reservoir used on
this power steering pump the power steering pump
will need to be removed from the engine.
(1) Remove the power steering pump from the
engine. Refer to the procedure in the Removal And
Installation Section in this group of the service man-
ual.
(2) Remove the 3 bolts (Fig. 14) mounting the
power steering fluid reservoir to the power steering
pump.
(3) Separate the power steering fluid reservoir
from the power steering pump (Fig. 15). The reser-
voir is separated from the power steering pump by
pulling it straight out of the pump.
INSTALL
(1) Lubricate the O-ring seal on the power steering
fluid reservoir (Fig. 16) with fresh clean power steer-
ing fluid.
(2) Install the power steering fluid reservoir on the
power steering pump (Fig. 15). The reservoir is
installed on the pump by pressing the nipple of the
reservoir straight into the pump without twisting or
rotating the reservoir.
(3) Install and securely tighten the three bolts
mounting the power steering fluid reservoir to the
power steering pump. Tighten bolt on pulley side to
13 N·m (115 in. lbs.). Tighten bolts on rear to 24 N·m
(212 in. lbs.).
(4) Install the power steering pump on the engine.
Refer to the procedure in the Removal And Installa-
tion Section in this group of the service manual.

REMOVAL AND INSTALLATION (Continued)
(1) Mount the power steering pump in a vise using
the mounting bosses for the power steering pump
(Fig. 17).
NOTE: Do not press or hammer on the shaft of the
power steering pump in an attempt to remove the
pulley. This will damage the internal components of
the power steering pump.
(2) Remove the power steering pump pulley from
the power steering pump shaft using Puller, Special
Tool C-4333 (Fig. 17).
ASSEMBLE
NOTE: Do not press or hammer on the shaft of the
power steering pump in an attempt to install the
pulley. This will damage the internal components of
the power steering pump.
(1) Place the power steering pump pulley on the
end of the power steering pump shaft. Make sure the
pulley is installed squarely on the end of the shaft.
CAUTION: When installing the pulley on the power
steering pump, Spacer, Special Tool 6936, MUST be
used. The spacer provides for the correct pulley
location on the power steering pump to provide
correct accessory drive belt alignment. The align-
ment is critical in controlling accessory drive belt
noise. It also prevents the pulley from contacting
the power steering pump when it is installed, caus-
ing power steering pump or pulley damage.
(2) Install Spacer, Special Tool 6936, into the hub
of the power steering pump pulley (Fig. 18).
(3) Insert the Pulley Installer, Special Tool C-4063,
(without adapters) through hole in spacer. Thread
the Installer into the end of the power steering pump
shaft (Fig. 19). Tighten the installer into pump shaft.
(4) Holding the Pulley Installer with one wrench
so it will not rotate, turn hex (Fig. 19) down threaded
rod of installer pushing the pulley onto the shaft of
the power steering pump (Fig. 19). Ensure that the
tool and the pulley remain aligned with the pump
shaft so pulley does not become cocked on shaft.
(5) Continue to push pulley onto shaft of power
steering pump until Pulley Installer will no longer
turn. This will ensure the spacer provided is fully
seated against the front of the power steering pump
shaft.
(6) Remove the Pulley Installer from the shaft of
the power steering pump. Remove the Spacer from
the hub of the power steering pump pulley.
(7) Verify the pulley turns properly on the pump
shaft.

DISASSEMBLY AND ASSEMBLY (Continued)
POWER STEERING PUMP PRESSURE FITTING
SEAL
To replace the O-ring seal on the pressure fitting of
the power steering pump, the power steering pump
will need to be removed from the engine.
DISASSEMBLE
(1) Remove the power steering pump from the
engine. Refer to the procedure in the Removal And
Installation Section in this group of the service man-
ual for the procedure to remove the power steering
pump from the engine the vehicle is equipped with.
(2) Remove the power steering pump pressure fit-
ting (Fig. 20) (Fig. 21) from the power steering pump.
Use care to prevent the flow control valve and
the spring from sliding out of the discharge/
flow control valve fitting.
(3) Remove and discard the O-ring seal from the
pressure fitting.
ASSEMBLE
(1) If necessary, clean and install flow control
valve and spring in pump housing bore.
(2) Install a new O-ring seal on the pressure fit-
ting.
(3) Install the pressure fitting into the power
steering pump. Tighten the pressure fitting to a
torque of 84 N·m (62 ft. lbs.).
(4) Install the power steering pump on the engine.
Refer to the procedure in the Removal And Installa-
tion Section in this group of the service manual for
the procedure to install the power steering pump on
the engine the vehicle is equipped with.
