Here's a general guide. Specifics may vary slightly depending on the exact engine in your Celebrity (2.0L, 2.5L, or 2.8L V6). Consult a repair manual specific to your year and engine for precise diagrams and torque specifications.
Tools You'll Need:
* New serpentine belt: Get the correct belt for your engine. Auto parts stores can help you identify the right one based on your vehicle's information.
* Socket wrench set: You'll likely need several sizes, depending on the tensioner pulley's bolt.
* Wrench (possibly): Depending on the tensioner design, you might need a wrench to loosen it.
* Pliers or channel-locks (possibly): Might be needed to help with tensioner release.
* Gloves: To protect your hands.
* Jack and jack stands (recommended): This makes accessing the belt much easier and safer. Never work under a car supported only by a jack.
* Repair manual (highly recommended): A manual will have diagrams showing the routing of the belt and specific instructions for your car's model.
Steps (General):
1. Preparation: Locate the alternator belt. It's a single serpentine belt that loops around the crankshaft pulley, alternator, power steering pump (if equipped), and possibly other accessories. Raise the front of your car using the jack and secure it safely with jack stands.
2. Identify Tensioner: Find the belt tensioner. It's a pulley with a mechanism to adjust belt tension. This is usually a spring-loaded device.
3. Release Tension: This is the trickiest part. The method varies slightly depending on the tensioner design:
* Lever-style tensioner: You'll likely need a socket wrench or wrench to loosen a bolt on the tensioner, allowing you to pull the tensioner with a lever (either a tool provided or something like pliers). This will relieve pressure on the belt.
* Other Designs: Some tensioners have different release mechanisms, Your repair manual will show you how.
4. Remove the Belt: Once the tension is released, carefully slip the old belt off the pulleys. Pay attention to the routing of the belt – you'll need to put the new belt back on in the same order.
5. Install New Belt: Carefully route the new belt around the pulleys in the same path as the old one. Make sure it sits correctly in all the grooves.
6. Release Tensioner: Once the belt is in place, release the tensioner and allow it to automatically tighten the belt.
7. Check Tension: Make sure the belt is taut, but not overly tight. You should be able to deflect it approximately ½ inch by pressing on it with your thumb. If the tension isn't correct, re-adjust.
8. Lower the Car: Carefully lower your car.
9. Reconnect Battery Terminal: Reconnect the negative battery terminal.
10. Start the Engine: Start the engine and check for any squeaking or unusual noises.
Important Considerations:
* Belt Routing: Pay very close attention to the path the belt takes. A wrongly routed belt can damage various components. Use your repair manual!
* Tension: Too loose, and the belt will slip. Too tight, and it will put unnecessary stress on the pulleys and alternator.
* Pulley Condition: While you're there, inspect the pulleys for wear and tear. Any signs of damage should be addressed.
If you're not comfortable performing this task yourself, it's best to take your car to a qualified mechanic. They have the experience and tools to do it correctly and safely. Remember to always consult your repair manual for the most accurate and model-specific instructions.
