Power Steering Pump: Service and Repair
Power Steering Pump
Initial Operation
STANDARD PROCEDURE - POWER STEERING PUMP - INITIAL OPERATION
WARNING: THE FLUID LEVEL SHOULD BE CHECKED WITH ENGINE OFF TO PREVENT INJURY FROM MOVING
COMPONENTS.
CAUTION: MOPAR (MS-9602) ATF+4 is to be used in the power steering system. No other power steering or automatic transmission fluid is to be
used in the system. Damage may result to the power steering pump and system if any other fluid is used, and do not overfill.
Wipe filler cap clean, then check the fluid level. The dipstick should indicate COLD when the fluid is at normal temperature.
1. Turn steering wheel all the way to the left
2. Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two (2) minutes.
3. Raise the front wheels off the ground.
4. Slowly turn the steering wheel lock-to-lock 20 times with the engine off while checking the fluid level.
NOTE: For vehicles with long return lines or oil coolers turn wheel 40 times.
5. Start the engine. With the engine idling maintain the fluid level.
6. Lower the front wheels and let the engine idle for two minutes.
7. Turn the steering wheel in both direction and verify power assist and quiet operation of the pump.
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.
Removal and Installation
REMOVAL
1. Drain and siphon the power steering fluid from the reservoir.
2. Remove the serpentine belt.
CAUTION: Do not remove the fitting on the pump that the high pressure hose screws into. The fitting may come loose unless it is backed up
using another wrench. If the fitting does come loose, it must be retightened before continuing. (57 - 67 Nm, 40 - 50 ft. lbs.) If this fitting comes
out of the pump body, the internal spring and valve parts will fall out of the pump and they cannot be reinstalled properly. If this occurs the pump
needs to be replaced with a new pump.
3. Disconnect the return hose.
4. Disconnect the pressure hose.
5. Access to remove the three bolts securing the pump to the cylinder head can be gained thru the pulley holes.
