I need detailed instructions on how to replace the belts

Hello,

The belts can be changed on this vehicle by using the adjustments on the alternator bracket and the A/C compressor bracket.
For the alternator loosen the nut of the pivot bolt.
Loosen the lock bolt.
This will allow you to move the alternator to release the tension on the belt.
For the A/C belt you will have to loosen the bolt on the tension pulley and that will allow you to get the belt out.
