2000 Hyundai Elantra Accessory belts (V, serpentine, a/C) replacement
 

Hi,
I was told I needed to replace the Accesory belts on the car (looked
visibly cracked). I am driving cross states (1400 miles) and was going
to replace just the V and serpentine belts. Was wondering how to go
about doing it (Is there a belt tnesioner that will make life easier).
Trying to look for diagrams etc online. Any help would be appreciated.
Thanks a ton.
