Here's a general overview of the process. Remember, this is not a complete guide and omits crucial safety steps and details. Incorrect procedures can lead to injury or damage to your vehicle's A/C system.
1. Safety First:
* Refrigerant Recovery: This is CRUCIAL. You MUST recover the refrigerant from the system using a proper A/C recovery machine. Releasing refrigerant into the atmosphere is illegal and harmful to the environment. If you don't have the equipment, take it to a professional.
* Eye Protection: Wear safety glasses or goggles throughout the process.
* Gloves: Wear gloves to protect your hands from sharp edges, oil, and potentially dirty parts.
2. Preparation:
* Disconnect the Battery: Disconnect the negative battery terminal to prevent accidental shorts.
* Gather Tools: You'll need various wrenches (likely metric), sockets, a clutch puller, possibly a serpentine belt tensioner tool, and potentially a torque wrench.
* Access the Compressor: Locate the A/C compressor (usually near the engine's front). You'll likely need to remove some components for better access, such as the serpentine belt and possibly other related parts. Consult your repair manual for the exact steps.
3. Removal of Old Clutch:
* Disconnect Electrical Connector: Disconnect the electrical connector from the compressor clutch.
* Remove Serpentine Belt: Remove the serpentine belt to access the compressor clutch. You may need a belt tensioner tool to relieve tension.
* Remove Clutch: Use a clutch puller to remove the old compressor clutch. This is usually a threaded device that screws onto the center of the clutch to pull it off the compressor shaft. Be careful not to damage the compressor shaft.
4. Installation of New Clutch:
* Clean the Shaft: Clean the compressor shaft thoroughly before installing the new clutch.
* Install New Clutch: Carefully align the new clutch and press it onto the compressor shaft using the correct tool or by hand. Ensure it's fully seated.
* Reattach Electrical Connector: Reconnect the electrical connector to the new clutch.
* Reinstall Serpentine Belt: Reinstall the serpentine belt.
5. Recharging the System:
* Vacuum the System: After reassembly, use a vacuum pump to evacuate any remaining air and moisture from the A/C system. This is essential for proper function and to prevent damage.
* Recharge with Refrigerant: Recharge the system with the correct amount and type of refrigerant using an A/C charging machine. Consult your repair manual for the proper refrigerant type and charge amount.
6. Testing:
* Start the Engine and Test: Start the engine and turn on the A/C. Check for leaks and proper cooling.
Again, this is a simplified overview. Consult a repair manual specific to your 2001 Ford Windstar SE for detailed, step-by-step instructions, torque specifications, and safety precautions. If you are not comfortable performing this repair, take your vehicle to a qualified mechanic. Improper handling of refrigerant and A/C system components can lead to serious injury or damage.
