The serpentine belt is starting to crack just slightly. What can i pt on it to prevent more cracking?
Nothing you can do to the existing belt. A new serpentine belt is what is needed. Cracking is the first sign the belt needs to be replaced. I went ahead and looked up the part for you. Followed up with the routing diagram and replacement procedure.
