  2.  
  3. Remove the pulley and the Woodruff key from the pump shaft.
  4.  
  5. Detach the intake and outlet hoses from the pump reservoir.

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. Installation is performed in the reverse order of removal. Note the following:

BLEEDING



  1. Jack up the front end of the car and safely support it with jackstands.
  2.  
  3. Check that the steering fluid is topped up to within the COLD LEVEL if cold, or the HOT LEVEL if the car has been running. Add fluid if necessary.
  4.  
  5. Start the engine and turn the steering wheel from lock to lock fully three or four times with the engine at idle.
  6.  
  7. Recheck the steering fluid level. Check that the fluid is not foamy or cloudy and does not rise over the maximum when the engine is stopped. With the engine running, the fluid should rise a maximum of 0.20 inch (5mm).
  8.  
  9. Start the engine and let it idle. Turn the steering wheel from lock to lock two or three times.
  10.  
  11. Lower the car to the ground. With the engine idling, turn the steering wheel from lock to lock several times. Center the steering wheel.
  12.  
  13. The bleeding is complete if the oil level in the reservoir has not risen excessively and there is no foaming or clouding of the fluid. If excessive rise and/or foaming is noticed, repeat Step 6 until the fluid level and condition is correct.
