Here's a general outline of the process. Specific steps may vary slightly depending on your exact Tahoe model (2WD vs 4WD, engine type). Always consult a repair manual specific to your year and model for detailed instructions and torque specifications.
Tools You'll Need:
* Socket set (metric): You'll need various sizes, likely including 10mm, 13mm, 15mm and possibly larger.
* Wrench set (metric): Similar to the socket set, you might need both open-end and box-end wrenches.
* Ratchet: A good quality ratchet will make the job much easier.
* Extensions and U-joints: These are helpful for reaching tight spaces.
* Torque wrench: Crucial for tightening bolts to the proper specification, preventing damage.
* Refrigerant recovery/recycling system: Absolutely essential to safely recover the refrigerant from the AC system before disconnecting anything. Improper handling of refrigerant is harmful to the environment and potentially dangerous.
* Vacuum pump: Used to evacuate the system after repairs.
* New compressor clutch: Make sure you get the correct part for your Tahoe.
* Possibly a clutch pulley puller: Depending on how stubborn the clutch is, you might need this specialized tool.
* Gloves, safety glasses, and appropriate work attire.
Steps (General):
1. Safety First: Disconnect the negative battery terminal. This prevents accidental shorts and protects electronic components.
2. Refrigerant Recovery: Use the refrigerant recovery system to safely remove the refrigerant from the AC system. This is extremely important.
3. Access the Compressor: Locate the AC compressor. On a Tahoe, it's typically located near the front of the engine. You'll likely need to remove some components to access it properly – this may involve removing belts, pulleys, and possibly other accessories. Consult your repair manual for the exact procedure for your specific vehicle.
4. Disconnect Components: Disconnect the electrical connector to the compressor clutch. You may also need to disconnect the AC lines (high and low pressure). Again, consult your repair manual for the exact location and procedure – be careful, as these lines contain pressure even after the refrigerant is recovered.
5. Remove the Old Clutch: This can be tricky. You may need to use a clutch pulley puller to remove the clutch from the compressor shaft.
6. Install the New Clutch: Carefully install the new compressor clutch onto the compressor shaft, ensuring it's properly seated.
7. Reconnect Components: Reconnect the AC lines (carefully), the electrical connector, and any other components you removed.
8. Evacuate and Recharge: Use the vacuum pump to evacuate the system thoroughly to remove any moisture or air. Then, recharge the system with the correct amount of refrigerant. Improperly charging the system can damage the compressor.
9. Test the System: Turn on the AC system and check for proper operation. Make sure there are no leaks and that the system is cooling efficiently.
Important Considerations:
* Repair Manual: A factory repair manual for your specific 2000 Chevy Tahoe is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Professional Help: If you lack the necessary experience or tools, it's best to have a qualified mechanic perform this repair. Improperly repairing the AC system can lead to costly damage.
* Environmental Concerns: Properly handling refrigerant is critical to protect the environment.
This is a general overview. The actual process can be more complex depending on your vehicle's specific configuration. Always refer to a repair manual for your 2000 Chevy Tahoe for precise instructions and safety precautions. Take your time, be careful, and if in doubt, seek professional help.
