WARNING: SAFETY GOGGLES SHOULD BE WORN
AT ALL TIMES DURING THE FOLLOWING PROCE-

Flushing is required when the power steering sys-
tem fluid has become contaminated. Contaminated
fluid in the steering system can cause seal deteriora-
tion and affect steering gear spool valve operation.
(1) Raise the front end of the vehicle off the
ground enough to allow the front wheels to freely
turn.
(2) Remove the return hose from the pump.
(3) Plug the return hose port on the pump.
(4) Place the open end of the return hose into a
large container to catch the draining fluid.
WARNING: ENGINE WILL BE RUNNING AS FLUID IS
ADDED TO PUMP FLUID RESERVOIR. TO AVOID
PERSONAL INJURY, BEWARE OF MOVING ENGINE
PARTS.
CAUTION: Do not reuse any drained power steering
fluid. Use only fresh Mopar power steering fluid or
equivalent.
(5) While an assistant is carefully filling the pump
reservoir with fresh power steering fluid, start the
engine.
(6) With the engine running at idle, turn the wheel
back and forth.
CAUTION: Do not contact or hold the wheel against

(7) Run approximately a quart of fluid through the
system, then stop the engine and install the return
hose back on the pump.

the Power Steering Pump Initial Operation proce-
dure listed in this section of the service manual
Power Steering Fluid
(Refer to 19 - STEERING/PUMP - STANDARD PRO-
