To replace the belt (which is the usual reason someone is looking to "tension" it), you'll need to:
1. Locate the tensioner: It's usually a pulley with a pivoting arm connected to it. You'll find it near the alternator. Consult your owner's manual or a repair manual for your specific year and engine to locate it precisely.
2. Release tension: There's usually a bolt or a special tool (sometimes a socket with a long extension and swivel) required to push the tensioner arm to relieve the belt tension. This will allow you to remove the belt from the pulleys. Again, your repair manual is vital here. *Never try to force the belt off; you risk damage to the alternator, tensioner or other components.*
3. Install the new belt: Carefully route the new belt over all the pulleys in the correct order (again, check your repair manual). Make sure the belt is seated correctly in all the grooves.
4. Release the tensioner: Once the belt is seated, release the tensioner. The tensioner will automatically provide the correct belt tension.
Important Considerations:
* Repair Manual: A repair manual specific to your Plymouth Breeze's year and engine is highly recommended. It will have diagrams showing the exact location of the tensioner, the procedure for releasing the tension, and the correct belt routing.
* Tools: You'll likely need a socket wrench, possibly a long extension and swivel, and possibly a specialized tensioner tool (depending on your Breeze's model year).
* Belt Replacement: Usually, if you're dealing with belt tension, it's because you're replacing a worn-out belt. It's much safer and simpler to just replace the belt.
If you're uncomfortable working on your car, take it to a qualified mechanic. Incorrectly handling the tensioner can lead to damage to your car's components.
