Here's a general outline. Consult a repair manual specific to your 1997 Ford Taurus SHO for detailed instructions and diagrams. This is crucial for proper torque specifications and component identification. Repair manuals can be found online or at auto parts stores.
Tools You'll Likely Need:
* Socket set: Various sizes, including likely a 10mm, and possibly others depending on the specific bolts securing the coil packs.
* Ratchet and extensions: To reach the coils comfortably.
* Wrench(es): May be needed depending on bolt/nut types.
* Torque wrench: Essential for proper tightening to avoid damage.
* Gloves: Protect your hands from grease and grime.
* Safety glasses: Protect your eyes from debris.
* Shop rags or paper towels: For cleaning.
* New ignition coils: Make sure you get the correct ones for your vehicle.
Steps (General Outline - Refer to your repair manual for specifics):
1. Disconnect the Battery: This is the most crucial first step. Disconnect the negative (-) terminal first to prevent accidental short circuits.
2. Access the Ignition Coils: The 1997 SHO's Yamaha 3.2L V6 has the ignition coils mounted directly on the spark plug tubes. This means you likely need to access them from the top of the engine. You'll probably need to remove some plastic engine covers to get a good view.
3. Disconnect Electrical Connectors: Carefully unplug the electrical connectors from the ignition coils. Take note of their locations for reassembly. Some connectors may require gentle prying with a small flat-head screwdriver.
4. Remove the Coils: Each coil is likely secured with bolts. Carefully remove these bolts (consult your repair manual for the correct size and torque specifications). Once the bolts are out, the coil should lift off. Again, refer to your repair manual for any unique removal procedures.
5. Install the New Coils: Carefully place the new ignition coils onto the spark plug tubes, ensuring they are seated correctly. Tighten the bolts to the specifications in your repair manual; over-tightening can damage the coils or the engine block.
6. Reconnect the Electrical Connectors: Carefully plug the electrical connectors back onto the new coils, ensuring they are firmly seated.
7. Reconnect the Battery: Reconnect the battery's positive (+) terminal.
8. Check for Leaks: Visually inspect for any leaks or loose connections.
9. Test the Vehicle: Start the engine and check for smooth operation. Listen for any misfires or unusual noises.
Important Considerations:
* Firing Order: The 1997 SHO's firing order is critical. If you misplace the coils, the engine will not run correctly, or at all. Your repair manual will have this information.
* Torque Specifications: Using the correct torque when tightening the bolts is paramount to prevent damage. Use a torque wrench and follow the specifications in your repair manual.
* Coil Pack Condition: Inspect the old coils for any signs of damage or wear, like cracks or corrosion, that might indicate a problem beyond just the coils themselves.
Again, this is a general outline. You absolutely must consult a repair manual specific to your 1997 Ford Taurus SHO before attempting this repair. Failure to do so could lead to engine damage or injury. If you're not comfortable with this level of automotive repair, take your vehicle to a professional mechanic.
