Here's a general overview of the process. This is NOT a comprehensive guide and specific steps may vary slightly depending on your Taurus's exact configuration. Always consult a repair manual specific to your 1999 Ford Taurus for detailed instructions and diagrams.
Tools You'll Likely Need:
* Wrench set (metric): Various sizes, likely including 10mm, 13mm, 15mm and possibly others.
* Socket set (metric): Similar size range as the wrenches.
* Ratchet and extensions: To reach difficult-to-access fasteners.
* Torque wrench: Essential for tightening bolts to the correct specification.
* Refrigerant recovery/recycling system: Absolutely crucial to safely remove the refrigerant from the system. Do not attempt this repair without one. Discharging refrigerant into the atmosphere is illegal and harmful to the environment.
* Safety glasses: Protect your eyes from flying debris.
* Gloves: Protect your hands.
* AC clutch puller: May be needed to remove the clutch from the compressor.
* New AC clutch: Make sure you get the correct replacement part for your model.
* Possibly a pulley holding tool: This prevents the pulley from spinning while you work on the clutch.
General Steps (Consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery cable. This prevents accidental shorts.
2. Refrigerant Recovery: Use your refrigerant recovery system to evacuate all refrigerant from the AC system. This is the most critical step to protect the environment and yourself.
3. Access the Compressor: Locate the AC compressor. This is usually near the engine's front on the passenger side. You'll likely need to remove some belts, pulleys, or other components to gain access.
4. Disconnect Electrical Connections: Carefully disconnect the electrical connector from the AC clutch.
5. Remove the AC Clutch: This is often the most challenging part. You might need to use an AC clutch puller to remove the clutch from the compressor shaft. Some designs may involve removing the pulley first.
6. Install the New Clutch: Carefully install the new AC clutch onto the compressor shaft, ensuring it's properly seated. Use the correct torque specification from your repair manual.
7. Reconnect Electrical Connections: Re-connect the electrical connector to the new clutch.
8. Reassemble: Reinstall any components you removed to access the compressor. Make sure everything is securely fastened.
9. Recharge the System: After reassembly, use your refrigerant recovery/recycling system to recharge the AC system with the proper amount and type of refrigerant (check your owner's manual). This usually requires a charging hose and gauges to monitor pressure.
10. Test the System: Turn on your car's AC to check for proper operation. Listen for any unusual noises and verify that the AC is blowing cold air.
Disclaimer: This is a simplified overview. Improper AC repair can lead to significant damage to your vehicle's AC system and potential injury. Consult a repair manual specific to your 1999 Ford Taurus and consider seeking professional help if you're unsure about any step. The environment and your safety are paramount. Improper handling of refrigerants is illegal and dangerous.
