Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your Alero's V6 engine.
* Wrench set: You'll likely need various sizes, including metric.
* Socket set: Again, likely metric sizes.
* Ratchet: A good quality ratchet will make the job easier.
* Jack and jack stands: Essential for safe working conditions. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Gloves: Protect your hands.
* Pliers or a belt tensioner tool: You might need a special tool to release tension on the tensioner pulley, but pliers might work depending on the design.
* Socket extension(s): May be necessary to reach some bolts.
* Wrench for the tensioner pulley bolt (if needed):
* Flashlight: For better visibility in tight spaces.
Steps:
1. Safety First: Park your Alero on a level surface, engage the parking brake, and use wheel chocks. Jack up the front of the car and securely support it on jack stands.
2. Locate the Serpentine Belt: Identify the serpentine belt routing. It's the long belt that runs around various pulleys (alternator, power steering pump, water pump, etc.). Take a picture or make a diagram *before* removing it, so you know how to put the new one on correctly.
3. Release Belt Tension: This is the most challenging part. The Alero likely uses a tensioner pulley. You'll need to locate the tensioner and figure out how to release its tension. This often involves using a wrench or a special tool to loosen a bolt or turn a lever on the tensioner. This step varies significantly between models, so refer to your specific repair manual! Once tension is released, the belt should be able to slip off the pulleys.
4. Remove the Old Belt: Carefully remove the old belt from each pulley.
5. Install the New Belt: Carefully route the new belt onto each pulley, following the diagram or picture you made. Ensure the belt is seated correctly on all pulleys. It may be easiest to install the belt around the tensioner pulley *first*.
6. Re-engage the Belt Tensioner: Once the belt is on all pulleys, carefully release the tensioner and allow it to return to its normal position. This will put the proper tension on the new belt. You might need to gently work the belt onto some of the pulleys while re-engaging the tensioner.
7. Check Belt Tension: After the belt is installed, check its tension by pressing on it midway between pulleys. It shouldn't be too loose or too tight. Consult your owner's manual or a repair manual for the correct tension specifications.
8. Lower the Car: Carefully lower your car from the jack stands.
9. Start the Engine: Start the engine and check for any squealing or unusual noises. If you hear any problems, double-check the belt routing and tension.
Important Notes:
* Repair Manual: A repair manual specific to your 2001 Oldsmobile Alero V6 is highly recommended. It will provide detailed diagrams and instructions for your specific model.
* Professional Help: If you're uncomfortable with any of these steps, or if you experience difficulties, it's best to seek professional help from a qualified mechanic. Incorrect installation can lead to serious engine damage.
* Disposal of Old Belt: Dispose of the old belt properly, according to your local regulations.
