Here's a general guide. This is not a substitute for a repair manual specific to your vehicle's engine. Consult your owner's manual or a repair manual for precise diagrams, torque specifications, and potential variations depending on your engine type (2.4L or 2.7L are common in the 2004 Sebring). Incorrect procedures can lead to damage.
Tools You'll Need:
* New serpentine belt: Get the correct belt for your specific engine. The part number is crucial and can be found in your owner's manual or online auto parts stores.
* Wrench(es): Sizes will vary depending on your specific tensioner and other components. Expect to need several sizes.
* Socket set: Possibly needed depending on the tensioner design.
* Ratchet: To use with the sockets and wrenches.
* Pliers (possibly needle-nose): Might be needed to help with belt routing.
* Jack and jack stands: For safer working conditions. Never work under a vehicle supported only by a jack.
* Gloves: Protect your hands.
* Repair manual (highly recommended): Provides diagrams, torque specs, and detailed procedures.
General Steps (Adapt to your specific vehicle):
1. Preparation: Locate the serpentine belt. It's usually a long, ribbed belt running around several pulleys (alternator, power steering pump, water pump, etc.). Consult your repair manual for its exact path. Jack up the front of your car and securely support it with jack stands.
2. Locate the Belt Tensioner: This is a device that allows you to release tension on the belt so you can remove and install it. It's usually spring-loaded and may require a specific wrench or socket to rotate it. Your repair manual will show you exactly where it is.
3. Release Belt Tension: Use the appropriate wrench or socket to rotate the tensioner, relieving the pressure on the belt. You may need to hold it in the released position while removing the belt.
4. Remove the Old Belt: Once the tension is released, carefully guide the belt off the pulleys. Pay attention to how it's routed; this will be important when installing the new belt.
5. Install the New Belt: Route the new belt onto the pulleys in the same order as the old one. Make sure it sits correctly in all the grooves.
6. Re-engage the Belt Tensioner: Release the tensioner and allow it to return to its normal position. The belt should now be taut. Double-check that the belt is properly seated on all pulleys.
7. Check Tension (Critical): Ensure the belt tension is correct. There should be very little give when you push on it midway between pulleys. Improper tension can lead to premature belt wear or failure.
8. Lower the Vehicle: Carefully lower your vehicle from the jack stands.
9. Start the Engine: Briefly start the engine to verify that everything is working correctly. Check for any squeaking or unusual noises from the belt or pulleys.
10. Final Check: Inspect the belt again after a short drive.
Important Considerations:
* Tensioner Type: The exact method for releasing tension on the serpentine belt varies depending on your car's model and engine. Some tensioners are released with a wrench, others might require a special tool.
* Belt Routing: Carefully note the path of the old belt before removal. Incorrect routing can cause damage to components.
* Pulleys: Inspect the pulleys while you have the belt off. Look for any damage or wear. Worn pulleys can cause premature belt failure.
* Safety First: Never work under a car supported only by a jack. Use jack stands for safety.
This is a general guide. Always consult your vehicle's repair manual for detailed instructions and diagrams specific to your 2004 Chrysler Sebring. If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. A poorly installed belt can lead to serious engine damage.
