SERVICE PROCEDURES
POWER STEERING PUMP – INITIAL OPERATION
WARNING: THE FLUID LEVEL SHOULD BE CHECKED WITH ENGINE OFF TO PREVENT INJURY FROM MOVING COMPONENTS.
CAUTION: Use MOPAR Power Steering Fluid or equivalent. Do not use automatic transmission fluid and do not overfill.
Wipe filler cap clean, then check the fluid level. The dipstick should indicate COLD when the fluid is at normal ambient temperature.
(1) Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two minutes.
(2) Start the engine and let run for a few seconds then turn engine off.
(3) Add fluid if necessary. Repeat the above proce­dure until the fluid level remains constant after run­ning the engine.
(4) Raise the front wheels off the ground.
(5) Slowly turn the steering wheel right and left, lightly contacting the wheel stops at least 20 times.
(6) Check the fluid level add if necessary.
(7) Lower the vehicle, start the engine and turn the steering wheel slowly from lock to lock.
(8) Stop the engine and check the fluid level and refill as required.
(9) If the fluid is extremely foamy or milky look­ing, allow the vehicle to stand a few minutes and repeat the procedure.
CAUTION: Do not run a vehicle with foamy fluid for an extended period. This may cause pump damage.

GENERAL INFORMATION
STEERING COLUMN
The tilt and standard column (Fig. 1) has been designed to be serviced as an assembly; less wiring, switches, shrouds, steering wheel, etc. Most steering column components can be serviced without remov­ing the steering column from the vehicle.
SERVICE PRECAUTIONS
Safety goggles should be worn at all times when working on steering columns.
To service the steering wheel, switches or airbag, refer to Group 8 M and follow all WARNINGS and CAUTIONS.
WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTRO-MECHANICAL UNIT. BEFORE

ATTEMPTING TO DIAGNOSE, REMOVE OR INSTALL THE AIRBAG SYSTEM COMPONENTS YOU MUST FIRST DISARM THE AIRBAG FIRING MECHANISM. FAILURE TO DO SO COULD RESULT IN ACCIDEN­TAL DEPLOYMENT OF THE AIRBAG AND POSSI­BLE PERSONAL INJURY.
WARNING: THE FASTENERS, SCREWS, AND BOLTS, ORIGINALLY USED FOR THE AIRBAG COM­PONENTS, HAVE SPECIAL COATINGS AND ARE SPECIFICALLY DESIGNED FOR THE AIRBAG SYS­TEM. THEY MUST NEVER BE REPLACED WITH ANY SUBSTITUTES. ANYTIME A NEW FASTENER IS NEEDED, REPLACE WITH THE CORRECT FASTEN­ERS PROVIDED IN THE SERVICE PACKAGE OR FASTENERS LISTED IN THE PARTS BOOKS.
