Here's a general overview of the process, but remember this is NOT a substitute for a proper repair manual:
Tools You'll Likely Need:
* Repair manual: Absolutely essential for specific instructions and torque specifications.
* Security bit set: The screws holding the steering column shroud and possibly the ignition cylinder itself are often security torx or other tamper-resistant types.
* Screwdrivers (Phillips and flathead): Various sizes.
* Sockets and wrenches: For removing the steering column shroud and possibly other components.
* Needle-nose pliers: May be needed to manipulate small parts.
* Ignition cylinder removal tool: Specialized tool to remove the cylinder without damaging it (highly recommended). Some use a special key.
* New ignition lock cylinder: Make sure you get the correct one for your 1993 Ford Tempo. You'll likely need your VIN (Vehicle Identification Number) to ensure compatibility.
* Penetrating oil (like PB Blaster): To help loosen any stuck screws or components.
* Protective gloves: To prevent cuts and grease from getting on your hands.
General Steps (Consult your repair manual for precise details):
1. Disconnect the battery: This is crucial to prevent electrical shorts and injury.
2. Remove the steering column shroud: This plastic cover protects the steering column and ignition components. You'll likely need to remove several screws, often security screws.
3. Remove the ignition switch: This is usually held in place by screws or a retaining clip. The repair manual will show you exactly how it's secured.
4. Remove the ignition lock cylinder: This is where the specialized removal tool is essential. Attempting to remove it without the proper tool can easily damage the cylinder and surrounding parts. The tool typically engages with the cylinder's retaining mechanism to allow for safe removal.
5. Install the new ignition lock cylinder: Carefully install the new cylinder using the reverse steps of removal, ensuring it's securely seated and all components are properly aligned.
6. Reassemble everything: Put the ignition switch, steering column shroud, and any other removed components back in place. Tighten all screws to the correct torque specifications (found in your repair manual).
7. Reconnect the battery: Test the new ignition cylinder to ensure it functions correctly.
Important Considerations:
* Steering wheel lock: Be aware of the steering wheel lock mechanism. You might need to carefully manipulate it to get access to the ignition cylinder.
* Keys: You'll need new keys that match the new ignition lock cylinder. Your local locksmith or auto parts store might be able to help cut new keys.
* Anti-theft system: If your Tempo has an anti-theft system, you may need to reprogram it after replacing the ignition cylinder. Consult your owner's manual or a qualified technician.
* Professional help: If you're not comfortable with this type of repair, it's best to take your car to a qualified mechanic.
This is a simplified overview. The actual process can be more complex. Always refer to a 1993 Ford Tempo repair manual for precise instructions and safety precautions. Improperly installing the ignition cylinder can damage your vehicle and create security vulnerabilities.
