Here's a general outline. Specifics may vary slightly depending on the exact engine in your Aveo (1.6L or 1.4L). Always consult your vehicle's repair manual for precise instructions and diagrams.
Tools You'll Likely Need:
* New serpentine belt: Make sure you get the correct size and type for your Aveo's engine.
* Socket wrench set: Various sizes will be needed, likely including metric sizes.
* Wrench set: Also likely metric.
* Ratchet: To use with the sockets.
* Pliers or needle-nose pliers: Possibly for accessing certain parts.
* Jack and jack stands: To safely lift the car.
* Wheel chocks: For safety.
* Gloves: To protect your hands.
* Shop rag or clean cloth: To wipe off grime and grease.
* Possibly a belt tensioner wrench: Some tensioners require a special tool. This is often the most challenging part of the job.
General Steps (Consult your repair manual for accurate specifics):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Raise the vehicle securely using a jack and jack stands. Never work under a car supported only by a jack.
2. Locate the Serpentine Belt: Identify the serpentine belt and its path around the various pulleys (alternator, power steering pump, water pump, etc.).
3. Loosen Tensioner: This is the most crucial and often difficult step. The tensioner pulley needs to be loosened to allow you to remove the belt. The method varies:
* Manual Tensioner: A wrench (often a long one for leverage) may be used to rotate the tensioner pulley, releasing tension on the belt. You may need to hold it in the released position while slipping the belt off.
* Automatic Tensioner: These use a spring and release mechanism. You may need a special tensioner wrench or may be able to manipulate it with a long pry bar or other tool. Be extremely cautious not to damage the tensioner.
4. Remove the Belt: Once the tension is released, carefully work the belt off of the pulleys. Note the routing of the belt before removal to ensure correct installation.
5. Install the New Belt: Carefully route the new belt around the pulleys in the same order as the old belt, following the routing diagram.
6. Tighten Tensioner: Once the new belt is installed, carefully re-tighten the tensioner pulley.
7. Lower the Vehicle: Carefully lower the vehicle using the jack.
8. Check Tension: Ensure the belt is properly tensioned. A slightly deflected belt, when pushed midway between two pulleys, is often sufficient.
9. Test the System: Start the engine and listen for any squealing or unusual sounds. Visually check all pulleys to make sure the belt is running smoothly and is not slipping.
Important Considerations:
* Repair Manual: A repair manual specific to your 2007 Chevrolet Aveo is highly recommended. It will provide detailed diagrams, torque specifications, and crucial step-by-step instructions.
* Tensioner Wrench: If your Aveo has an automatic tensioner, you might need a special wrench to properly release and re-tighten it.
* YouTube Videos: Search YouTube for "2007 Chevy Aveo serpentine belt replacement." You may find helpful videos demonstrating the process. However, always cross-reference with your repair manual.
Remember, this is a general guide. Improper installation can lead to damage to your engine and other components. If you are uncomfortable with any part of this process, seek professional help from a qualified mechanic.
