Freightliner FLA/FLB/FLC/FLD/FLL. Manual - part 35
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.
7.
Fill the reservoir with approved power steering
fluid. See
IMPORTANT: Do not start the engine while
draining the system.
8.
Place the disconnected end of the steering gear-
to-reservoir hose in a drain bucket. 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.
9.
Remove the caps (as applicable) from the ports
and fitting. For a 3-line system, remove the fitting
from the pump-to-reservoir hose and attach it to
the reservoir port. Connect the hose(s) to the
reservoir. Tighten each hose fitting nut finger-
tight, then tighten with a wrench until resistance
is felt. Tighten one-sixth turn more. Do not over-
tighten.
Remove the jack stands and lower the vehicle.
10. Fill the reservoir with the same fluid used above,
as needed. Start the engine and let it idle. Have
someone turn the steering wheel to full stop in
each direction until no bubbles are seen in the
reservoir. Shut down the engine.
11. Install the cover and capscrew on the reservoir.
Tighten the capscrew 10 to 15 lbf·ft (14 to 20
N·m). If equipped with a thumbscrew, install the
cover and thumbscrew, and tighten the thumb-
screw finger-tight. For a 9-quart reservoir, install
a new O-ring, the band clamp, and the cover.
Tighten the clamp bolts 40 lbf·ft (54 N·m).
Install the dipstick.
12. Start the engine. Check the reservoir for fluid
leaks around the cover. If fluid leaks are present,
shut down the engine and install a new reservoir
cover gasket.
13. Check the power steering fluid level in the reser-
voir. If the fluid level is low, add more of the
same fluid used above to bring the level up to
the full mark on the dipstick.
