Fluid level should be checked with the engine OFF to prevent personal injury from moving parts and to assure an accurate fluid level reading.
MOPAR® Power Steering Fluid + 4 or MOPAR® ATF+4 Automatic Transmission Fluid is to be used in the power steering system. Both Fluids have the same material standard specifications (MS-9602). 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 another fluid is used. Do not overfill the system.
If the air is not purged from the power steering system correctly, pump failure could result.
Be sure the vacuum tool used in the following procedure is clean and free of any fluids.
- Before servicing the vehicle, refer to the Precautions Section.
Check the fluid level.
- The power steering fluid level can be viewed through the side of the power steering fluid reservoir.
- Compare the fluid level to the markings on the side of the reservoir. When the fluid is at normal ambient temperature, approximately 70-80° F (21-27° C), the fluid level should read between the MAX and MIN markings.
When the fluid is hot, the fluid level is allowed to read up to the MAX line.
NOTEDo not fill fluid beyond the MAX mark. Check the cap seal for damage and replace if needed.
- Remove the cap from the fluid reservoir and fill the power steering fluid reservoir up to the MAX marking with MOPAR® Power Steering Fluid + 4 or MOPAR® ATF+4 Automatic Transmission Fluid.
Tightly insert the Power Steering Cap Adapter (4), Special Tool 9688, into the mouth of the reservoir (3).
NOTEFailure to use a vacuum pump reservoir (1) may allow power steering fluid to be sucked into the hand vacuum pump.
Attach the Hand Vacuum Pump (2), Special Tool C-4207, or equivalent, with reservoir (1) attached, to the Power Steering Cap Adapter (4).
WARNINGDo not run the vehicle while vacuum is applied to the power steering system. Damage to the power steering pump can occur.
NOTEWhen performing the following step make sure the vacuum level is maintained during the entire time period.
- Using Hand Vacuum Pump (2), apply 20-25 inches Hg (68-85 kPa) of vacuum to the system for a minimum of 3 minutes.
- Slowly release the vacuum and remove the Special Tools.
- Adjust the fluid level as necessary.
- Repeat above steps until the fluid no longer drops when vacuum is applied.
Start the engine and cycle the steering wheel lock-to-lock 3 times.
NOTEDo not hold the steering wheel at the stops.
- Stop the engine and check for leaks at all connections.
Check for any signs of air in the reservoir and check the fluid level. If air is present, repeat the procedure as necessary.
WARNINGDo not run a vehicle with foamy fluid for an extended period. This may cause pump damage.
