3.4L (VIN X) Engine



Specific to:

Buick Century 1997-2000

Buick Regal 1997-2000

Chevrolet Lumina 1997-2000

Chevrolet Monte Carlo 1997-2000

Oldsmobile Cutlass Supreme 1997

Oldsmobile Intrigue 1998-2000


WARNING
The subframe of the vehicle carrying the engine and transaxle must be loosened and lowered a small amount to allow removal the rack and pinion assembly. This requires lifting and jacking equipment that likely is unavailable to the nonprofessional. There is a potential for vehicle damage. This is not a job for the inexperienced or ill-equipped.

  1. Remove the air cleaner and duct assembly.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Center the front wheels, then remove the key to lock the steering column. This is important to protect the SIR (air bag) coil inside the steering column. This procedure requires the steering intermediate shaft to be disconnected from the rack and pinion stub shaft. If the steering column is allowed to turn, the SIR coil will become uncentered, requiring a rewind procedure or unnecessary SIR coil replacement.
  6.  
  7. An engine support fixture is required to hold the weight of the powertrain. Install tools J 28467-A, J 28467-90 and J 36462, or equivalent engine support fixtures.
  8.  
  9. Raise and safely support the vehicle.
  10.  


WARNING
Verify that the front wheels are straight ahead and that the ignition switch is in the LOCK position. Failure to follow these procedures could result in damage to the SIR coil assembly.

  1. Remove the left wheel and tire assembly.
  2.  
  3. Loosen the right side engine splash shield.
  4.  
  5. Remove both tie rod ends from the knuckle using the procedures found in this section.
  6.  


CAUTION
Failure to disconnect the intermediate shaft from the rack and pinion stub shaft may result in damage to the steering gear. This damage may cause a loss of steering control and may cause personal injury.

  1. Remove the intermediate shaft lower pinch bolt at the steering gear (end of the steering column shaft).
  2.  
  3. Remove the intermediate shaft from the stub shaft.
  4.  
  5. Detach the electrical connection from the steering gear pressure switch.
  6.  
  7. Remove the exhaust pipe and catalytic converter assembly.
  8.  
  9. Using safety stands, securely support the vehicle. A hydraulic jack may be useful to support the subframe and then to lower it after the retaining bolts are loosened. Unfasten the frame retaining bolts, then carefully lower the frame about 3 inches (7.6 cm).
  10.  
  11. Unfasten the steering gear heat shield screws, then remove the heat shield.
  12.  
  13. Remove the power steering line clamp from the steering gear.
  14.  
  15. Unfasten the steering gear bolts.
  16.  
  17. Disconnect and plug the pressure and return lines from the steering gear.
  18.  
  19. Remove the steering gear through the left wheel opening.
  20.  
  21. Replace the stud shaft shields.
  22.  

To install:

  1. Install the rack assembly through the left wheel opening.
  2.  
  3. Unplug and connect the pressure and return lines to the steering gear.
  4.  
  5. Install the steering gear bolts and tighten to 59 ft. lbs. (80 Nm).
  6.  
  7. Fasten the power steering line clamp at the steering gear.
  8.  
  9. Install the steering gear heat shield and secure with the retaining screws. Tighten the screws to 54 inch lbs. (6 Nm).
  10.  
  11. Raise the frame assembly and align the steering gear stub shaft to the intermediate steering shaft.
  12.  
  13. Install the frame retaining bolts and tighten to 125 ft. lbs. (170 Nm). Remove the safety stands supporting the subframe.
  14.  
  15. Install the exhaust pipe and catalytic converter assembly.
  16.  
  17. Attach the electrical connection to the steering gear pressure switch.
  18.  


WARNING
When installing the steering column to the intermediate shaft, make sure that the shaft is seated before pinch bolt installation. If the bolt is inserted into the coupling before shaft installation, the two mating shafts may disengage. The front wheels on the vehicle should still be straight ahead and set the column should still be locked. Failure to follow these procedures could result in damage to the SIR (air bag) coil assembly.

  1. Install the intermediate steering shaft pinch bolt at the steering gear. Tighten the bolt to 35 ft. lbs. (47 Nm).
  2.  
  3. Install the both tie rod ends, as outlined earlier in this section.
  4.  
  5. Tighten the right side engine splash shield.
  6.  
  7. Install the left tire and wheel assembly.
  8.  
  9. Carefully lower the vehicle.
  10.  
  11. Remove the engine support fixtures. Connect the negative battery cable, then install the air cleaner and duct assembly.
  12.  
  13. Bleed the power steering system, as outlined later in this section.
