What am I really looking for when inspecting alternator and PS belts on car? Autozone video says new belts have V shaped grooves and completely used belts the grooves look U shaped. How can I use this knowledge to inspect my belts on car? Maybe I should get a new belt and compare them side by side using a flashlight? I guess I just answered this question. Thanks

From reading the manual, you don't need to change the belt till it's missing pieces of ribs or fraying.

Milage is best indicator for change besides cracks and such the belt ply wealens and stretches and brakes. 45K is as far as I go cheep insurance to prevent stuck on road and possible engine damage
