Power Steering Bleeding: Service and Repair11 steps
⚠ WARNING
Fluid level should be checked with the engine OFF to prevent personal injury from moving parts and to assure an accurate fluid level reading.
△ CAUTION
Mopar(R) Power Steering Fluid + 4 or Mopar(R) 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.
△ CAUTION
If the air is not purged from the power steering system correctly, pump failure could result.
ℹ NOTE
Be sure the vacuum tool used in the following procedure is clean and free of any fluids.
△ CAUTION
Do not fill fluid beyond the MAX mark. Check cap seal for damage and replace if needed.
△ CAUTION
Failure to use a vacuum pump reservoir (1) may allow power steering fluid to be sucked into the hand vacuum pump.
△ CAUTION
Do not run the vehicle while vacuum is applied to the power steering system. Damage to the power steering pump can occur.
ℹ NOTE
When performing the following step make sure the vacuum level is maintained during the entire time period.
ℹ NOTE
Do not hold the steering wheel at the stops.

  1. 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 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.
  2. Remove the cap from the fluid reservoir and fill the power steering fluid reservoir up to the MAX marking with Mopar(R) Power Steering Fluid + 4 or Mopar(R) ATF+4 Automatic Transmission Fluid.
  3. Tightly insert Power Steering Cap Adapter (4), Special Tool , into the mouth of the reservoir (3).
  4. Attach Hand Vacuum Pump (2), Special Tool or equivalent, with reservoir (1) attached, to the Power Steering Cap Adapter (4).
  5. Using Hand Vacuum Pump (2), apply 68-85 kPa (20-25 in. Hg) of vacuum to the system for a minimum of three minutes.
  6. Slowly release the vacuum and remove the special tools.
  7. Adjust the fluid level as necessary. Refer to 1.
  8. Repeat 1 through 7 until the fluid no longer drops when vacuum is applied.
  9. Start the engine and cycle the steering wheel lock-to-lock three times.
  10. Stop the engine and check for leaks at all connections.
  11. Check for any signs of air in the reservoir and check the fluid level. If air is present, repeat the procedure as necessary.

POWER STEERING SYSTEM BLEED PROCEDURE📷 2
WARNING: The fluid level should be checked with engine off to prevent injury from moving components.
CAUTION: 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.
CAUTION: If 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

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.
