Tools You'll Likely Need:
* New alternator belt: Ensure you get the correct belt size for your vehicle.
* Socket set and wrench: Sizes will depend on your car, but you'll need to loosen the alternator mounting bolts.
* Possibly a belt tensioner tool: Some 106s have an automatic tensioner, while others might require a special tool to relieve tension on the belt. Check your repair manual.
* Jack and axle stands (highly recommended): Safely raising and supporting your car is crucial for access and safety.
* Gloves: Protect your hands.
* Wrench or socket for the tensioner pulley bolt (if applicable).
General Steps (Always Refer to Your Repair Manual):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Raise the car using a jack and secure it on axle stands. Never work under a car supported only by a jack.
2. Locate the Alternator and Belt: Identify the alternator and the belt you need to replace.
3. Loosen the Alternator Mounting Bolts (if needed): This might be necessary to provide slack in the belt. The exact location and number of bolts will depend on your specific engine.
4. Release Belt Tension: This is the most crucial and potentially tricky part.
* Automatic Tensioner: If your car has an automatic belt tensioner, it usually has a bolt or a lever that you need to turn or push to relieve the tension. This might be accessed from the top or bottom of the engine bay. Your repair manual will show you exactly how to do this.
* Manual Tensioner: If you have a manual tensioner, you'll likely need a special tool to put pressure on it, releasing the tension on the belt. Again, your manual will be essential here.
5. Remove the Old Belt: Once the tension is released, carefully remove the old belt from the pulleys.
6. Install the New Belt: Route the new belt around the pulleys in the same path as the old belt. Make sure it sits correctly in the grooves of each pulley.
7. Tighten the Belt Tensioner (if applicable): If it's a manual tensioner, now is the time to tighten it up by removing the tensioner tool. For automatic tensioners, the tension should return automatically.
8. Tighten Alternator Mounting Bolts: If you had to loosen them earlier, tighten them back to the manufacturer's torque specifications (found in your repair manual).
9. Lower the Car: Carefully lower the car from the axle stands.
10. Check Belt Tension: After lowering the car, check that the belt is properly tensioned. You should be able to press down slightly on the longest span of the belt midway between the pulleys—it shouldn't deflect excessively. If unsure, consult your repair manual.
11. Start the Engine: Start the engine and check for any unusual noises or squealing, which may indicate incorrect installation or tension.
Important Notes:
* Repair Manual: This is crucial. Pictures and diagrams in a manual specific to your Peugeot 106's year and engine are invaluable.
* Torque Specifications: Always tighten bolts to the manufacturer's recommended torque specifications to prevent damage. Use a torque wrench if possible.
* Safety: Working on your car can be dangerous. If you're not comfortable performing this task, take it to a qualified mechanic.
Failing to follow these steps correctly could lead to belt slippage, premature wear, or even damage to the alternator or other engine components. Always prioritize safety and refer to your vehicle's repair manual for specific instructions.
