Removal Procedure

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
  1. Relieve the fuel system pressure. Fuel Pressure Relief
  2. Disconnect the battery negative cable. Battery Negative Cable Disconnection and Connection
  3. Drain the cooling system. Refer to Cooling System Draining and Filling (LF4 Static Fill) , or Cooling System Draining and Filling (LF4 GE 47716)
    4. CAUTION:

    With wheels of the vehicle facing straight ahead, secure the steering wheel utilizing steering column anti-rotation pin, steering column lock, or a strap to prevent rotation. Locking of the steering column will prevent damage and a possible malfunction of the SIR system. The steering wheel must be secured in position before disconnecting the following components:

    • The steering column
    • The intermediate shaft (s)
    • The steering gear

    After disconnecting these components, do not rotate the steering wheel or move the front tires and wheels. Failure to follow this procedure may cause the SIR coil assembly to become un-centered and cause possible damage to the SIR coil. If you think the SIR coil has become un-centered, refer to your specific SIR coil's centering procedure to re-center SIR Coil.

  5. Secure the steering wheel so it will not turn when the mid intermediate steering shaft is disconnected.
