Power Steering Pump Initial Operation

WARNING: The fluid level should be checked and adjusted with the engine off to prevent injury from moving engine components.

CAUTION: Mopar® Power Steering fluid + 4 or Mopar® ATF+4 Automatic Transmission Fluid 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.

Fill the power steering fluid reservoir to the proper level, then let the fluid settle for at least two minutes. (Refer to STEERING/PUMP/FLUID - STANDARD PROCEDURE - POWER STEERING FLUID LEVEL CHECKING) .
Raise the front wheels off the ground.
Slowly turn the steering wheel lock-to-lock 20 times with the engine off while checking the fluid level periodically.
NOTE: Vehicles with long return lines or oil coolers turn wheel 40 times.
Start the engine. With the engine idling maintain the fluid level.
Lower the front wheels and let the engine idle for two minutes.
Turn the steering wheel in both directions 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.
Stop the engine. Check the fluid level and refill as required.
