  4.  
  5. Drain the fluid from the power steering pump reservoir.
  6.  
  7. Disconnect the return hose from the reservoir tank.
  8.  
  9. Disconnect the pressure tube from the power steering pump.
  10.  
  11. Push on the drive belt to hold the pulley in place and remove the pulley set nut. Loosen the idler pulley set nut and adjusting bolt. Remove the drive belt and loosen the drive pulley to remove the Woodruff key.

Tie the hose ends up high so the fluid cannot flow out of them. Drain or plug the pump to prevent fluid leakage.

  1. Remove the bolt from the rear mounting brace.
  2.  
  3. Remove the front bracket bolts and withdraw the pump.
  4.  
  5. Tighten the pump pulley mounting bolt to 29 ft. lbs. (39 Nm).
  6.  
  7. Adjust the pump drive belt tension. The belt should deflect 3.3-23mm (0.13-0.93 in.) under thumb pressure applied midway between the air pump and the power steering pump.
  8.  
  9. Fill the reservoir with DEXRON®II automatic transmission fluid. Bleed the air from the system.

  2.  
  3. Drain the fluid from the power steering reservoir tank.
  4.  
  5. At the power steering pump, disconnect the return hose and the pressure tube.

  12.  

BELT ADJUSTMENT



  1. Inspect the power steering drive belt to see that it is not cracked or worn. Be sure that its surfaces are free of grease or oil.
  2.  
  3. Push down on the belt halfway between the fan and the alternator pulleys (or crankshaft pulley) with thumb pressure. Belt deflection should be 9.5-13mm ( 3 / 8 - 1 / 2 in.).
  4.  
  5. If the belt tension requires adjustment, loosen the adjusting link bolt and move the power steering pump until the proper belt tension is obtained.
  6.  
  7. Do not over-tighten the belt, as damage to the power steering pump bearings could result. Tighten the adjusting link bolt.
  8.  
  9. Drive the vehicle and re-check the belt tension. Adjust as necessary.
  10.  

SYSTEM BLEEDING



  1. Raise and support the vehicle safely.
  2.  
  3. Fill the pump reservoir with the proper fluid.
  4.  
  5. Rotate the steering wheel from lock-to-lock several times. Add fluid if necessary.
  6.  
  7. With the steering wheel turned fully to one lock, crank the starter while watching the fluid level in the reservoir.
  8.  

Do not start the engine. Operate the starter with a remote starter switch or have an assistant do it from inside the car. Do not run the starter for prolonged periods.

  1. Repeat Step 4 with the steering wheel turned to the opposite lock.
  2.  
  3. With the engine idling, turn the steering wheel from lock-to-lock several times.
  4.  
  5. Lower the front of the vehicle and repeat Step 6.
  6.  
  7. Center the wheel at the midpoint of its travel. Stop the engine.
  8.  
  9. The fluid level should not have risen more than 5mm (0.2 in.), repeat Step 7.
  10.  
  11. Check for fluid leakage.
