1. Turn off the engine, apply the parking brakes,
and chock the tires.
2. Open the hood.
3. Remove the fill cap, nut, and cover from the

mission fluid.
WARNING
Fill only with approved clean fluid. Do not mix
fluid types. Any mixture or any unapproved fluid
could lead to seal deterioration and leaks. Fluid
leakage could cause loss of power steering assist,
possibly resulting in personal injury and property
damage.
9. Place the end of the hose in the drain pan. Do
not start the engine while draining the sys-
tem. Raise the front of the vehicle with a floor
jack and support it with jack stands. Have some-
one turn the steering wheel to full lock left and
right, and capture the fluid flowing from the hose
in the drain pan. Add fluid to the reservoir, as
needed. Continue turning the steering wheel until
clean power steering fluid flows from the hose.
10. Remove the plug from the reservoir and connect
the hose to the reservoir. Tighten the hose fitting
nut finger tight. Then with a wrench, tighten until
there is firm resistance. Tighten one-sixth turn
more. Do not overtighten.
