6C-10 Power Assisted Steering System:
Power Steering System Bleeding
NOTE
• Use clean, new power steering fluid type
only. See the Maintenance and Lubrication
subsection for fluid specifications. Refer
to "Fluid and Lubricant
Recommendations: ".
• Hoses touching the frame, body or engine
may cause system noise. Verify that the
hoses do not touch any other part of the
vehicle.
• Loose connections may not leak, but could
allow air into the steering system. Verify
that all hose connections are tight.
NOTE
Power steering fluid level must be maintained
throughout bleed procedure.
1. Fill pump reservoir with fluid to minimum system
level, FULL COLD level, or middle of hash mark on
cap stick fluid level indicator.
NOTE
With hydro-boost only, the oil level will
appear falsely high if the hydro-boost
accumulator is not fully charged. Do not
apply the brake pedal with the engine OFF.
This will discharge the hydro-boost
accumulator.
2. If equipped with hydro-boost, fully charge the hydro-
boost accumulator using the following procedure:
a. Start the engine.
b. Firmly apply the brake pedal 10-15 times.
c. Turn the engine OFF.
3. Raise the vehicle until the front wheels are off the
ground. Refer to "Lifting and Jacking the Vehicle: ".
4. Key on engine OFF, turn the steering wheel from
stop to stop 12 times.
Vehicles equipped with hydro-boost systems or
longer length power steering hoses may require
turns up to 15 to 20 stop to stops.
5. Verify power steering fluid level per operating
specification. Refer to "Checking and Adding Power
Steering Fluid".
6. Start the engine. Rotate steering wheel from left to
right. Check for sign of cavitation or fluid aeration
(pump noise/whining).
7. Verify the fluid level. Repeat the bleed procedure, if
necessary.
Repair Instructions
Checking and Adding Power Steering Fluid
!
When adding fluid or making a complete fluid
change, always use the proper power
steering fluid. Failure to use the proper fluid
will cause hose and seal damage and fluid
leaks.
1. Clean the area surrounding the reservoir cap.
2. Remove the reservoir cap.
3. Inspect the power steering pump fluid level at regular
intervals. Use the appropriate procedure below.
Add fluid when required. Refer to "Fluid and
Lubricant Recommendations: ".
Fluid Is Hot
a. Run the engine until the fluid reaches about
b. Turn the engine OFF.
c. Remove the reservoir cap.
d. Inspect the fluid level on the capstick.
e. Ensure that the fluid level is at the HOT/FULL
4. If the fluid level is low, add power steering fluid to the
proper level.
5. Install the reservoir cap.
6. When checking the fluid level after servicing the
steering system, bleed the air from the system. Refer
to "Power Steering System Bleeding".
Power Steering System Flushing
NOTE
Do not reuse any drained power steering
fluid regardless of appearance or condition.
1. Turn OFF the engine.
2. Raise the front end of the vehicle off the ground until
the tires and wheels turn freely. Refer to "Lifting and
Jacking the Vehicle: ".
3. Place a large container under the fluid return hose in
order to collect the draining fluid.
4. Remove the fluid return hose at the power steering
pump reservoir inlet connection.
5. Plug the reservoir return hose inlet connection on the
power steering pump.
NOTE
This step may require 4 L (4 qt) of power
steering fluid until the draining fluid appears
clear.
CAUTION
80°C (170°F).
