Fig. Fig. 1: Unfasten the power steering pump drive adjusting bolt, then remove the drive belt

  1. Remove the pump drive belt tension adjusting bolt. Disconnect the belt from the pump.
  2.  
  3. Disconnect the return and pressure hoses from the pump. Cover the hose connector and union on the pump and open ends of the hoses to avoid the entrance of dirt.
  4.  
  5. Remove the front bracket from the engine on 1972 and later model vehicles equipped with V8 engines.
  6.  
  7. Remove the two nuts which secure the rear of the pump to the bracket, and the two bolts which secure the front of the pump to the bracket and remove the pump.
  8.  
  9. To install, position the pump in the bracket and install the rear attaching screws. On 1972 and later model vehicles equipped with V8 engines, install the front bracket.
  10.  
  11. Connect the hydraulic hoses. Adjust the drive belt tension.
  12.  
  13. Fill the pump reservoir to the correct level.
  14.  
  15. Start the engine and wait for at least three minutes before turning the steering wheel. Check the level frequently during this time and add fluid as necessary.
  16.  
  17. Slowly turn the steering wheel through its entire range a few times with the engine running. Recheck the level and inspect for possible leaks.
  18.  

If air becomes trapped in the fluid, the pump may become noisy until all of the air is out. This may take some time, since trapped air does not bleed out rapidly.

ENGINES WITH A V-TYPE DRIVE BELT
  1. Loosen the power steering pump adjustment and pivot bolts.
  2.  
  3. Insert the drive lug of a 1 / 2 in. drive ratchet into the adjustment hole in the pump rear bracket and move the pump to relieve tension on the belt.
  4.  
  5. Remove the drive belt.
  6.  
  7. Remove the air cleaner.
  8.  
  9. Disconnect the hoses at the pump and cap the hose ends.
  10.  
  11. Remove the front bracket-to-engine bolts.
  12.  
  13. Support the pump with your hand. Remove the pump-to-rear bracket nuts.
  14.  
  15. Lift out the pump.
  16.  
  17. Installation is the reverse of removal. Torque the pump-to-bracket nuts to 28 ft. lb.; the bracket-to-engine bolts to 33 ft. lb. Install the drive belt. Using the 1 / 2 in. drive ratchet, move the pump to put tension on the belt, tighten the pump adjustment and pivot bolts and check the belt tension with a tension gauge at the mid-point of its longest straight run. Belt tension should be 120-160 ft. lb. for a new belt, or 90-115 ft. lb. for a used belt.
  18.  
  19. When the tension is achieved, tighten the pump pivot nut to 21 ft. lb.; the adjustment bolt to 21 ft. lb.
