7.
Fill the reservoir with approved power steering
fluid. See
Table 1
.
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.
8.
Place the disconnected end of the steering gear-
to-reservoir hose in a drain bucket.
Do not start
the engine while draining the system.
Raise the
front of the vehicle with a floor jack and support
it with jack stands. Have someone turn the steer-
ing wheel to full lock left and right, and capture
the fluid flowing from the hose in the drain
bucket. Add fluid to the reservoir, as needed.
Continue turning the steering wheel until clean
power steering fluid flows from the hose into the
drain bucket. Remove the plug from the reservoir
and reconnect the steering gear-to-reservoir
hose to the reservoir.
9.
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.
Remove the jack stands and lower the vehicle.
10. Fill the reservoir with approved fluid, as needed.
Start the engine and let it idle. Have someone
turn the steering wheel from lock to lock until no
bubbles are seen in the reservoir. Turn off the
engine.
11. Install a new cover gasket, the cover, and the
3/8–16 hexnut. Tighten the hexnut 28 lbf·ft (38
N·m). Install the dipstick.
12. Start the engine and check the power steering
reservoir fluid level. If the fluid level is low, add
more of the approved fluid to bring the level up
to the full mark on the dipstick.
