However, if you're determined to understand the *general* process (again, do not attempt this yourself), it involves these steps:
1. Disconnect the Battery: This is crucial to prevent accidental deployment. Disconnect the negative (-) terminal first, then the positive (+). Wait at least 10 minutes to allow the system to completely discharge.
2. Remove Steering Wheel: This usually requires specialized tools and knowledge of the specific torque specifications for the steering wheel bolt(s). You'll likely need a steering wheel puller. Be aware of the clock spring, a delicate component that connects the steering wheel to the airbag module. Damage to the clock spring can result in loss of various steering wheel-mounted controls.
3. Disconnect the Airbag: Once the steering wheel is removed, you'll find the airbag module. There will be electrical connectors attached. Carefully disconnect these connectors. Never use force. Some connectors have a locking mechanism that must be released. Consult a repair manual for your specific vehicle.
4. Remove the Airbag: The airbag itself is usually held in place by screws or clips. Remove these fasteners carefully.
5. Install the New Airbag: Install the new airbag, ensuring it's properly seated and aligned.
6. Reconnect the Airbag: Reconnect the electrical connectors, again ensuring they're properly seated.
7. Reinstall the Steering Wheel: Reinstall the steering wheel, tightening the bolt(s) to the manufacturer's specified torque.
8. Reconnect the Battery: Reconnect the battery's positive (+) terminal first, then the negative (-) terminal.
Important Considerations:
* Repair Manual: You absolutely need a repair manual specific to a 2002 Mercury Cougar. This manual will provide detailed instructions, torque specifications, and diagrams.
* Safety Precautions: Wear safety glasses and gloves throughout the entire process.
* Disposal of Old Airbag: Dispose of the old airbag properly. Contact your local waste disposal facility for instructions.
* Airbag Module Reset: After the replacement, the airbag module might need to be reset using a scan tool. A qualified mechanic will have this equipment.
Again, I strongly advise against attempting this repair yourself. The risks are too significant. Take your vehicle to a qualified mechanic or automotive repair shop. The cost of professional repair is far less than the cost of a potential injury or death.
