FLUID ISSUES

CONDITIONPOSSIBLE CAUSESEVALUATION/CORRECTION
LOW FLUID LEVEL WITH VISIBLE LEAK1. 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. 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 (7 kPa) 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. Refer to STANDARD PROCEDURE .

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

WARNINGFluid level should be checked with the engine OFF to prevent personal injury from moving parts and to assure an accurate fluid level reading.
CAUTIONThere is an Electro-Hydraulic Power Steering (EHPS) pump on some vehicles requiring a different fluid. Do not mix power steering fluid types. Damage may result to the power steering pump and system if any other fluid is used. The mechanical power steering pump systems on this vehicle require the use of Power Steering Fluid +4, which meets material specification MS-9602 or equivalent. The EHPS system uses fluid which meets material specification MS-11655 or equivalent. Do not overfill.
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. Refer to «FLUID, STANDARD PROCEDURE»(ref-489286-S35246970972012072600000) . When the fluid is at normal ambient temperature, approximately 21° - 27° C (70° - 80° F), the fluid level should read between the MAX and MIN markings. When the fluid is hot, fluid level is allowed to read up to the MAX line. CAUTION: Do not fill fluid beyond the MAX mark. Check cap seal for damage and replace if needed.
  2. Remove the cap from the fluid reservoir and fill the power steering fluid reservoir up to the MAX marking with the correct power steering fluid as follows: With a mechanical power steering pump - Mopar® Power Steering Fluid +4 or equivalent, which meets Chrysler Material Standard MS-9602. With an Electro-Hydraulic Power Steering (EHPS) - Mopar® Hydraulic Power Steering Fluid or equivalent, which meets Chrysler Material Standard MS-11655.
  3. For EHPS systems, cycle the steering wheel lock-to-lock three times with the engine off .
  4. Tightly insert the (special tool #9688A, Cap Adapter, Power Steering Pump) (4) into the mouth of the reservoir (3): CAUTION: Failure to use a vacuum pump reservoir (1) may allow power steering fluid to be sucked into the hand vacuum pump.
  5. Attach (special tool #C-4207-A, Vacuum Pump, Hand) (2) or equivalent, with reservoir (1) attached, to the Power Steering Cap Adaptor (4). CAUTION: Do not run the vehicle 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.
  6. Using Hand Vacuum Pump (2), apply 68-85 kPa (20-25 in. Hg) of vacuum to the system for a minimum of three minutes.
  7. Slowly release the vacuum and remove the special tools.
  8. Adjust the fluid level as necessary. Refer to 1 .
  9. Repeat 1 through 8 until the fluid no longer drops when vacuum is applied.
  10. Start the engine and cycle the steering wheel lock-to-lock three times. NOTE: Do not hold the steering wheel at the stops.
  11. Stop the engine and check for leaks at all connections.
  12. Check for any signs of air in the reservoir and check the fluid level. If air is present, repeat the procedure as necessary.

NON-SRT POWER STEERING FLUID LEVEL CHECKING

WARNINGFluid level should be checked with the engine OFF to prevent personal injury from moving parts and to assure an accurate fluid level reading.
CAUTIONThis vehicle features an Electro Hydraulic Power Steering (EHPS) pump which requires a different power steering fluid. Do not mix power steering fluid types. Damage may result to the power steering pump and system if any other fluid is used. The EHPS system uses fluid which meets material specification MS-11655 or equivalent.

Note. Although not required at specific intervals, the fluid level may be checked periodically. Check the fluid level anytime there is a system noise or fluid leak suspected.

Note. The power steering fluid reservoir (4) is integrated with the Electro Hydraulic Power Steering (EHPS) pump.

  1. Raise and support vehicle. Refer to «HOISTING, STANDARD PROCEDURE»(ref-489279-S05318852982012072600000) .
  2. Remove right front wheel mounting nuts, then tire and wheel assembly.
  3. Remove right front wheelhouse splash shield. Refer to «SHIELD, SPLASH, FRONT WHEELHOUSE, REMOVAL»(ref-489285-S40885179682012072600000) or «SHIELD, SPLASH, REAR WHEELHOUSE, REMOVAL»(ref-489285-S25264909042012072600000) .
  4. Ensure that the fluid is at the correct level in the power steering reservoir (4).

SRT POWER STEERING FLUID LEVEL CHECKING

WARNINGFluid level should be checked with the engine OFF to prevent personal injury from moving parts and to assure an accurate fluid level reading.
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.

Note. Although not required at specific intervals, the fluid level may be checked periodically. Check the fluid level anytime there is a system noise or fluid leak suspected.

The power steering fluid level can be viewed on the dipstick attached to the filler cap. There are two sides to the dipstick, one is for checking the fluid when it is cold, the other is for checking the fluid when it is hot. Before opening the power steering system, wipe the reservoir filler cap free of dirt and debris. Remove the cap and check the fluid level on its dipstick.

Use the COLD side of the dipstick (1) to measure 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 ADD and FULL COLD lines.

Use the HOT side of the dipstick (2) to measure when the vehicle has been running and the fluid is hot. When the fluid is hot, the fluid level is allowed to read up to the FULL HOT line. Only add fluid to the system when the vehicle is cold.

Use only Mopar® Power Steering Fluid + 4 or Mopar® ATF+4 Automatic Transmission Fluid in the power steering system. Do not overfill the power steering system.
