Tools You'll Need:
* New alternator belt: Make sure you get the correct size. Your owner's manual or an auto parts store can help you identify the correct size.
* Socket wrench set: You'll likely need a few different sizes, probably including a 13mm and 15mm.
* Ratchet: To use with your sockets.
* Wrench (possibly): Depending on the tensioner design, you might need a wrench.
* Gloves: To protect your hands.
* Jack and jack stands (optional but highly recommended): Making the job safer and easier by lifting the car.
* Wheel chocks (if using a jack): Essential for safety.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake firmly, and chock the wheels if you are jacking up the car. Disconnect the negative (-) battery terminal to prevent accidental shorts.
2. Locate the Alternator and Belt: The alternator is usually located on the front of the engine, near the crankshaft pulley. The belt runs between the crankshaft pulley, the alternator, and possibly other components like the power steering pump and water pump.
3. Identify the Tensioner: There's a tensioner pulley that allows you to loosen the belt. This is usually a spring-loaded device. Some older vehicles have a manual tensioner that may require a wrench to loosen; others have an automatic tensioner that's released by moving a lever or arm.
4. Loosen the Belt Tension: This is the crucial step. Inspect the tensioner.
* If it's a manual tensioner: Use the appropriate wrench to loosen the tensioner. This might involve turning a bolt or nut.
* If it's an automatic tensioner: There should be a mechanism (often a lever or arm) that you can manipulate to release the tension on the belt. You might need to use a long pry bar or similar tool to help you reach and move the lever. Consult a repair manual for your specific vehicle for details on the location and operation of your tensioner.
5. Remove the Belt: Once the tension is released, carefully slip the belt off the pulleys. It might help to use a flat-head screwdriver or a similar tool to gently pry the belt off.
6. Install the New Belt: Carefully align the new belt onto the pulleys, starting with the largest pulley (usually the crankshaft pulley). Make sure the belt is seated correctly on all the pulleys.
7. Tighten the Belt Tension: Release the tensioner mechanism (if it's an automatic one). If it's manual, tighten the tensioner bolt. The belt should be snug but not overly tight. You should be able to twist the belt about 90 degrees with moderate pressure. Too loose, and it will squeal; too tight, and it will put unnecessary stress on the bearings.
8. Reconnect the Battery: Reconnect the negative (-) battery terminal.
9. Test: Start the engine and check for any squealing or slipping from the belt. If you hear squealing, recheck the tension.
Important Considerations:
* Repair Manual: A Haynes or Chilton repair manual specific to your 1984 Chevrolet Celebrity is highly recommended. These manuals provide detailed diagrams and instructions for your particular vehicle.
* Diagram: Look for a diagram showing the belt routing. Getting the belt on the wrong pulleys can damage the engine components.
* Belt Condition: While you're at it, inspect the other belts (like the serpentine belt if you have one) for wear and tear. If they look worn, consider replacing them as well.
If you're uncomfortable performing this repair yourself, take your vehicle to a qualified mechanic. This is a relatively simple repair, but incorrect procedures can lead to damage to the alternator or other engine components.
