FLUID ISSUES

CONDITIONPOSSIBLE CAUSESEVALUATION/CORRECTION
LOW FLUID LEVEL WITH VISIBLE LEAK.1. Loose power steering hose fittings or connections.1. Check torque on all tube nuts (at gear and pump). Inspect clamps at all rubber hose connections for correct position, damage and tension. Tighten tube nuts as required. Reposition or replace clamps at hose connections. Clean joints and reinspect for leaks.
2. Damaged or missing O-ring at power steering hose tube nuts.2. Remove tube nut and inspect O-ring. If damaged or missing, replace O-ring. Clean joints and reinspect for leaks.
3. Power steering line or hose failure.3. Clean fluid from around suspect areas. Run vehicle and inspect for leaks. Look inside reservoir to see if air is being ingested. Replace hoses as necessary.
4. Power steering component leaking (reservoir, pump, gear).4. Clean fluid from around suspect areas. Run vehicle and inspect for leaks. Look inside reservoir to see if air is being ingested. Replace power steering component as necessary.
AERATED FLUID*1. Low power steering fluid level.1. Check fluid level and fill to proper level as necessary. Check for leaks. Make sure all air is bled from system.
2. Air leak at power steering supply hose, reservoir or pump.2. Inspect components. Put a hand vacuum pump on the reservoir and verify that the system can keep a vacuum. System should not lose more than 1 psi in 2 minutes (make sure vacuum pump is sealed well to the reservoir).
3. Air leak at power steering supply hose, reservoir or pump.3. Inspect components. Place a hand vacuum pump with Adapter 9688 on reservoir and verify that system can sustain vacuum. System should not lose more than 1 psi in 2 minutes (make sure vacuum pump is sealed well to the reservoir). Replace steering component as necessary.
RESERVOIR FLUID OVERFLOW OR FLUID THAT IS MILKY IN COLOR1. Water contamination of power steering fluid.1. Inspect fluid for milky appearance. Completely drain power steering fluid. Refill and bleed system. See STANDARD PROCEDURE .

FLUID ISSUES

Note. Extremely cold temperatures may cause power steering fluid aeration. The air should work its way out of the system as the fluid warms.

WARNINGThe fluid level should be checked with engine off to prevent injury from moving components.
CAUTIONMopar® 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.
CAUTIONIf the air is not purged from the power steering system correctly, pump failure could result.

Note. Be sure the vacuum tool used in the following procedure is clean and free of any fluids.

  1. Check the fluid level. As measured on the side of the reservoir, the level should indicate between MAX and MIN when the fluid is at normal ambient temperature. Adjust the fluid level as necessary. See «STANDARD PROCEDURE»(ref-285324-S09186192622008052100000) .
  2. Tightly insert Power Steering Cap Adapter (4), Special Tool 9688, into the mouth of the reservoir (3). CAUTION: Failure to use a the vacuum pump reservoir (1) may allow power steering fluid to be sucked into the hand vacuum pump.
  3. Attach Hand Vacuum Pump (2), Special Tool C-4207 or equivalent, with reservoir (1) attached, to the Power Steering Cap Adapter (4). CAUTION: Do not run the engine while vacuum is applied to the power steering system. Damage to the power steering pump can occur. NOTE: When performing the following step make sure the vacuum level is maintained during the entire time period.
  4. Using Hand Vacuum Pump (2), apply 68-85 kPa (20-25 in. Hg) of vacuum to the system for a minimum of three minutes.
  5. Slowly release the vacuum and remove the special tools.
  6. Adjust the fluid level as necessary. Refer to step 1 .
  7. Repeat step 1 through step 6 until the fluid no longer drops when vacuum is applied.
  8. Start the engine and cycle the steering wheel lock-to-lock three times. NOTE: Do not hold the steering wheel at the stops.
  9. Stop the engine and check for leaks at all connections.
  10. Check for any signs of air in the reservoir and check the fluid level. If air is present, repeat the procedure as necessary.

Scheme 13: STEERING COLUMN

The tilt and standard column has been designed to be serviced as an assembly; less wiring (1), switches, shrouds, steering wheel, etc. Most steering column components can be serviced without removing the steering column from the vehicle.

To service the steering wheel, switches or airbag, refer to RESTRAINTS - SERVICE INFORMATION article and follow all WARNINGS and CAUTIONS.

Note. When servicing the steering wheel after removing the old bolt a new bolt must be used when installing.

Note. When servicing the steering coupler a new bolt must be used when installing.

WARNINGThe airbag system is a sensitive, complex electro-mechanical unit. Before attempting to diagnose, remove or install the airbag system components you must first disconnect and isolate the battery negative (ground) cable. Then wait two minutes for the system capacitor to discharge. Failure to do so could result in accidental deployment of the airbag and possible personal injury. 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.
CAUTIONDo not hammer on steering column shaft. This may cause damage to the shaft or bearing.
CAUTIONDo not attempt to remove or modify the park lock slider or link.
CAUTIONDo not attempt to remove the pivot bolts to disassemble the tilting mechanism. Do not remove shaft lock plate or plate retainer. This will damage the column.

POWER STEERING FLUID LEVEL CHECKING

WARNINGFLUID LEVEL SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT PERSONAL INJURY FROM MOVING PARTS.
CAUTIONMOPAR® 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.

The power steering fluid level can be viewed on the dipstick attached to the filler cap. There are two ranges listed on the dipstick, COLD and HOT. Before opening power steering system, wipe the reservoir filler cap free of dirt and debris. Remove the cap and check the fluid level on its dipstick. When the fluid is at normal ambient temperature, approximately 21°C to 27°C (70°F to 80°F), the fluid level should read between the minimum and maximum area of the cold range. When the fluid is hot, fluid level is allowed to read up to the highest end of the HOT range. Only add fluid when the vehicle is cold.

Use only Mopar® ATF+4 . Do not overfill the power steering system.
