freightliner MC - Power Steering Fluid and Filter Changing

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.
IMPORTANT: Do not confuse coolant with hy-
draulic fluid. Both are pink in color.
3. Fill the reservoir to a level between the MIN and
MAX marks. Use only Dexron III automatic trans-
mission fluid (ATF), or an equivalent. See
Table 1 for approved power steering fluid.
4. Replace the reservoir cap.
46–03 Power Steering Fluid
and Filter Changing
WARNING
Fill only with approved clean fluid. Failure to use
the proper fluid could cause seal deterioration and
leaks. Fluid leaks could eventually cause loss of
power steering assist. This could lead to an acci-
dent resulting in personal injury or property dam-
age. Wear eye protection when changing the fluid
and filter.
1. Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
rear tires.
2. Place a drain pan under the power steering res-
ervoir.
3. Remove the steering gear-to-reservoir return
hose at the reservoir and position it to drain into
the pan.
4. Plug the return line fitting on the reservoir.
5. Remove the reservoir cover.
For the 1.6- and 2-quart reservoir, unscrew and
remove the reservoir cover. See
Fig. 2.
For the 4-quart reservoir, loosen and then re-
move the retaining ring, filter top plate, and gas-
ket. See
Fig. 3.
NOTE: Always replace the power steering reser-
voir filter when changing the fluid.
6. Remove the power steering filter. It may be nec-
essary to wiggle the filter to remove it from its
base. Do not use pliers to aid in removal of the
filter; pliers could cause metal chips to enter the
steering system.
7. Clean the inside of the reservoir using a lint-free
cloth.
8. Raise the front of the vehicle with a floor jack
and support it with jack stands.
9. Place the disconnected end of the steering gear-
to-reservoir hose in a drain pan.
IMPORTANT: Do not start the engine while
draining the system.
10. Have someone turn the steering wheel to full
lock left and right several times until clean power
