GENERAL PROCEDURES
System Flushing —
CIII Power Steering Pump
WARNING: Do not mix oil types. Any mixture or any unapproved oil can lead to seal
deterioration and leaks. A leak can ultimately cause loss of fluid, which can result in a loss of
power steering assist.
1. Remove the fuel pump fuse from the battery junction box.
2. Disconnect the power steering return hose. Plug the reservoir.
3. Attach an extension hose between the power steering return hose and an empty container.
4. Raise the front wheels off the floor. For additional information, refer to Section 100 - 02 .
5. Check the fluid level. If necessary, fill the reservoir to the correct level. zUse Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent.
6. CAUTION: Do not crank the engine for more than 15 seconds at a time. Allow the
starter to cool for 1 minute before cranking again. Premature starter failure can occur.
CAUTION: Do not hold the steering wheel against the stops for more than three to
five seconds at a time. Damage to the power steering pump could occur.
Turn the steering wheel from stop- to-stop while cranking the engine until the fluid exiting the
power steering return hose is clear of all contamination and foreign material.
zAdd Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent as
needed.
7. Lower the vehicle.
8. Disconnect the extension hose from the power steering return hose. Remove the plug. Attach the power steering return hose to the reservoir.

NOTE:
All fasteners are important because they can affect the performance of vital parts and systems.
Incorrect installation of the fasteners can result in major repair expenses. They must be installed new
with fasteners of the same part number if installation becomes necessary. Do not install a new part of
lesser quality or substitute a design. Torque values must be used as specified during assembly to
make sure these parts function correctly.
The body of the steering column (3C529) is made of magnesium die castings. The steering column is
attached to a support that is an integral part of the instrument panel. The lower attachments of the
steering column are through a bracket that bends during collapse. The upper attachments are through
plastic shear modules that separate from the main casting during collapse. A clip and washer are
attached to the shear modules to reduce steering column shake and to assist in installation of the
steering column. 45 N621906 Nut

GENERAL PROCEDURES
Supplemental Restraint System (SRS) Deactivation and
Reactivation
Deactivation
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint
system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury
in the event of an accidental deployment.
WARNING: After deployment, the air bag surface can contain deposits of sodium
hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your
hands with soap and water afterwards.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air
bag deployment, which can result in personal injury.
WARNING: Air bag modules with discolored or damaged trim covers must be installed
new, not repainted.
WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and possible
violation of vehicle safety standards.
1. WARNING: To avoid accidental deployment and possible personal injury, the
backup power supply must be depleted before repairing or replacing any front or side air
bag supplemental restraint system (SRS) components and before servicing, replacing,
adjusting or striking components near the front or side air bag sensors, such as doors,
instrument panel, console, door latches, strikers, seats and hood latches.
Please refer to the appropriate vehicle shop manual to determine location of the front air
bag sensors.
The side air bag sensors are located at or near the base of the B- pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and
wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). SECTION 211-
