Tools You'll Need:
* New serpentine belt: Make sure to get the correct belt size for your LeBaron's year and engine. The size is usually printed on the old belt. Auto parts stores can help you find the right one.
* Wrench(es): You'll likely need various sized wrenches to loosen the tensioner pulley(s). The sizes depend on your specific LeBaron model.
* Socket set and ratchet: This can be helpful for accessing some of the bolts.
* Jack and jack stands (highly recommended): This will give you better access and ensure safety.
* Gloves: Protect your hands.
* Shop rags: To clean up any grease or dirt.
* Pry bar (optional, but helpful): For some tensioners.
* Owner's manual: For specific torque specs and diagrams
Steps:
1. Safety First: Engage the parking brake firmly. Place the vehicle on jack stands for safety. Never work under a car supported only by a jack.
2. Locate the Serpentine Belt: Identify the serpentine belt that runs around the crankshaft pulley, water pump, alternator, power steering pump, and other accessories.
3. Identify the Belt Tensioner: Locate the tensioner pulley. This is a pulley that's used to create tension on the belt so you can easily remove and install it. It usually has a spring and some type of release mechanism (either a bolt or a lever).
4. Release Belt Tension: This is the most crucial and potentially tricky step. The method varies slightly depending on your LeBaron's year and engine.
* Bolt-Type Tensioner: Use the appropriate wrench to loosen the bolt on the tensioner. This will release tension on the belt. You may need to use a pry bar to hold the tensioner in the released position while you slip the belt off.
* Lever-Type Tensioner: There's usually a lever that you can turn or push to release tension. Consult your repair manual for the correct procedure.
5. Remove the Old Belt: Once tension is released, carefully work the belt off of each pulley, starting with the one that has the most slack.
6. Install the New Belt: Route the new belt onto the pulleys in the same path as the old one. Make sure it fits snugly onto all pulleys.
7. Re-tighten the Tensioner: Tighten the tensioner bolt (or return the lever) to its original position.
8. Check Belt Alignment: Make sure the belt is properly seated on all the pulleys and there is even tension.
9. Lower the Vehicle (if raised): Carefully lower the vehicle to the ground once you are sure the belt is installed correctly.
10. Test the Vehicle: Start the engine and check for any squealing or unusual noises. If you hear anything, stop immediately and re-check the belt installation. Also check the belt tension, and ensure all pulleys are rotating smoothly.
Important Notes:
* Consult your vehicle's repair manual: This is crucial. The specific procedure for releasing the tensioner and routing the belt will be detailed in the manual. Improper tensioning can damage the belt or other components.
* Torque Specifications: Tighten all bolts to the manufacturer's specified torque. Over-tightening can damage components.
* Belt Routing: Pay close attention to the routing of the belt. A misrouted belt can cause serious problems.
If you're uncomfortable performing this repair yourself, take your LeBaron to a qualified mechanic. It's safer and more reliable.
