If you mean the ignition lock cylinder:

Ignition Lock Cylinder CAUTION
If the car is equipped with an air bag, do not service the steering column or dashboard components. Extreme danger of air bag deployment exists even with the battery removed! Serious injury could occur. REMOVAL & INSTALLATION Without Air Bag

  1. Place the ignition switch in the RUN position.
  2. Remove the lockplate, turn signal switch and buzzer switch.
  3. Remove the screw and lock cylinder. NOTE: If the screw is dropped on removal, it could fall into the column, requiring complete disassembly to retrieve the screw. To install:
  4. Rotate the cylinder clockwise to align cylinder key with the keyway in the housing.
  5. Push the lock all the way in.
  6. Install the screw. Tighten the screw to 14 inch lbs. (2 Nm) for adjustable columns and 25 inch lbs. (3 Nm) for standard columns.
With Air Bag CAUTION
Before proceeding, refer to Section 6 for information on disabling and enabling the SIR (air bag) system; otherwise, serious injury could occur.
  1. Turn the steering wheel so the vehicles wheels are pointed straight ahead.
  2. Place the ignition switch into the LOCK position to prevent undercentering of the coil assembly.
  3. Disable the SIR system. Disconnect the negative battery cable.
  4. Remove the coil assembly retaining ring, then disconnect the inflatable restraint coil assembly. Let the switch hang freely if removal is not needed. To remove the coil assembly proceed.
  5. Remove the wave washer, then the shaft retaining lock ring with tool J-23653-SIR to push down on the shaft lock. Dispose of the ring, it is not reusable. Fig. 1: Special tool J-23653-SIR or equivalent is required for pushing down the shaft lock to remove the shaft ring how to replace the ignition on a 1991 oldsmobile - 86818085.gif
  6. Remove the shaft lock, then disconnect the canceling cam assembly.
  7. Remove the upper bearing spring, race seat and race.
  8. Position the turn signal to the right turn (up) position.
  9. Remove the multi-function lever and hazard knob assembly. Unfasten the round washer head screw and signal switch arm, along with the turn signal switch screws.
  10. Remove the turn signal switch assembly by unfastening the connector from the bulkhead connector. Gently pull on the harness through the column and disconnect.
  11. Make sure the coil assembly does not become uncentered, this could happen if the centering spring is pushed down letting the hub rotate while the coil is removed from the steering column.
  12. Remove the inflatable restraint coil assembly with the wiring harness from the column assembly.
  13. Remove the wire protector, then attach a length of mechanics wire to the coil terminal connector to aid in reassembly. Then gently pull the wire through the column.
  14. Remove the key from the steering column lock cylinder set, then remove the buzzer switch assembly.
  15. Reinsert the key into the lock cylinder, turn it to the LOCK position.
  16. Remove the lock retaining screw, then the cylinder. To install: NOTE: Make sure all fasteners are securely seated before applying the necessary torque. If you fail to do so, component damage or malfunctioning of the steering column may occur.
  17. Install the lock cylinder assembly, insert the retaining screw, then tighten to 22 inch lbs. (2.5 Nm).
  18. Insert the key into the lock cylinder. Install the buzzer switch assembly. Turn the key to the LOCK position.

  21. Attach the signal switch arm with the round washer head screw, tighten the screw to 20 inch lbs. (2 Nm).
  22. Install the hazard knob assembly and the multi-function lever.
  23. Install the inner race, upper bearing race seat and spring. Attach the turn signal cancelling cam assembly, apply grease for lubrication.
  24. Replace the shaft lock and install a new shaft lock retaining ring. Use tool J-23653–SIR or equivalent to push down on the shaft lock. The ring must be firmly seated in the groove on the shaft. NOTE: Set the steering shaft so that the block tooth on the race and upper shaft is at the 12 o'clock position. The wheel on the car should be straight ahead. Set the ignition switch to the LOCK position, as this will ensure no damage to the coil assembly.
  25. Install the wave washer, then attach the coil assembly, make sure it is centered correctly. Fig. 2: Centering the coil assembly is important in assembling the column assembly 86818086.gif

  26. Attach the coil assembly retaining ring, the ring must be firmly seated in the groove on the shaft.
  27. Gently pull the lower coil assembly, turn signal, and pivot (pulse) wires to remove any kinks that may be inside the steering column assembly. If you fail to do this you can damage the wiring.

SOURCE: ignition

First you need to go to the local parts store and get a steering wheel puller and a clock spring compressor tool. You can rent them but just cheaper to buy it and return it. I got mind like 35 bucks together.
You will remove the horn button just by pulling it towards you be careful not to rip the horn wire out. Next there may be a retainer clip remove it with a pair of needle nose pliers. Next get a breaker bar or a impact gun to back the center nut off. Once off use the steering wheel puller by inserting the threaded bolts into the threaded holes directly beside the center pin. ease the puller onto the center pin and tighten down until the steering wheel starts to move back towards you continue until off. On some trucks there is a steel plate covering the housing to the left side and towards the top are two small torx screws remove them and remove the cover. Next grab your clock spring compressor and install it similar to the way you did the wheel puller you will tighten down the center bolt slightly decompressing the clock spring. as you compress the clock spring look to the center there is a small retainer clip that looks like it is made into the center pin pry the clip off making sure not to damage it and remove the compressor tool, remove the clock spring making sure to pay attention on how it comes apart you can put it all back together. Remove the turn signal switch should be 3 phillips head screws. You may need to disconnect the horn wire at this point it just turns slightly and pulls out. After you remove the clock spring you will see the lock cylinder body, follow the body towards the center pin. There will be a small torx bit to it will be silver and very shinny at the end of the lock housing remove it and slide the lock cylinder out. Install the new one and reverse the steps.
hope this helps.....good luck!

How to replace starter in a 1991 Cutlass Ciera


I had to do mine recently. You have to remove the radiator to make elbow room. Then jack up the car, as the trick is to remove the motor mount, then jack up the motor itself as high as you can get it to go. At that point you should be able to see the starter. That frees up getting to the starter. The rest is easy, no explanation required, it's just figuring out how to get to it that's a bear. Good luck.

Could someone have removed my pcv valve before I got the 91 olds cutlass cierra and it would still run?


Sure they could have.

BUT NOT LIKLEY.

The PVC valve is needed to clear the mixed gases from the crank case

RECOMENDATION:

Go to your local Parts store and have the attendant point out your PVC valve and replace it.

1991 is way past due for replacement.

Hope this tip helps.

How do I change out headlight bulb on 91 olds cutlass cierra


Behind the headlight, you should see the nylon bulb holder. Turn it counter clockwise, about a 1/4 turn, and it should come out. Pull the old bulb straight out, and replace it with the new one. Don't touch the glass part of the new bulb with bare fingers, or you'll be replacing it again. Use cotton gloves or a paper towel. Put the holder back in the headlight, turn it clockwise until it locks.
