Before you begin:
* Safety First: Disconnect the negative battery cable to prevent electrical shorts.
* Gather Tools: You'll need a socket set (metric), wrenches (metric), a ratchet, extensions, possibly a breaker bar, a jack and jack stands (for easier access), and potentially a serpentine belt tool (depending on the tensioner design). Some tensioners use a special tool while others can be loosened manually.
* New Parts: Obtain a new tensioner pulley and possibly a new serpentine belt, as it's wise to replace it while you're in there.
General Procedure (Adapt to your specific engine):
1. Locate the Tensioner: The tensioner is usually located on the engine's front, near the serpentine belt. It's a pulley on an arm that's spring-loaded to keep tension on the belt.
2. Access the Tensioner: This might involve removing some plastic covers, air intake components, or other parts to gain access. Your repair manual will show you exactly what needs to be removed.
3. Release Tension: This is the trickiest part.
* Manual Tensioner: Some tensioners have a bolt that you can loosen to relieve tension on the belt. This allows you to remove the belt.
* Automatic Tensioner: Others use a lever or similar mechanism. You might need a special tool to push or pull on the tensioner arm to release tension on the belt. Again, check your manual; forcing it incorrectly can damage the tensioner.
4. Remove the Old Belt: Once the tension is released, carefully route the belt off the pulleys. Note the order of the belt on the pulleys, take pictures, or draw a diagram if needed – this will be crucial for reinstallation.
5. Remove the Old Tensioner: Locate the bolts holding the tensioner in place and carefully remove them. You might need to support the tensioner as you remove the bolts.
6. Install the New Tensioner: Carefully install the new tensioner, making sure it's seated correctly. Tighten the bolts to the torque specifications in your repair manual.
7. Install the New Belt: Carefully route the new belt onto the pulleys in the correct order (refer to your notes or diagram). Make sure the belt is seated properly on all the pulleys.
8. Re-tension the Belt: Check the belt tension. It should be firm but not excessively tight. If it's a manual tensioner, tighten the bolt. Consult your repair manual for the correct tension. Incorrect tension can lead to premature belt wear.
9. Reassemble Everything: Put back all the components you removed earlier.
10. Reconnect the Battery: Reconnect the negative battery cable.
11. Test: Start the engine and check for any squealing or unusual noises. Check the belt for proper alignment and tension.
Important Considerations:
* Torque Specifications: Using the correct torque for the bolts is critical to prevent damage. Use a torque wrench.
* Repair Manual: A repair manual specific to your 1996 Chrysler Sebring is absolutely essential. This will give you detailed instructions and diagrams, making the job much easier and safer.
* Professional Help: If you're not comfortable working on your car, take it to a qualified mechanic. Improper repair can lead to serious damage.
This is a general guide. Always consult a repair manual specific to your vehicle for detailed instructions and safety precautions. Remember safety first!
