Drive belts pics inside

[ReniFx]

Just recently i noticed that my (i guess they called drive belts) in front of the engine were cracked. I did not pay attention the first time so i went and ordered one serpentine belt "gates" as im looking today again i see that there is another small best nex to the big one. Sorry for the bad explanation, here are a few pics,i need the name of the other belt (the small one on the right side of engine).
Thanks

You need two belts when replacing belts. Serpentine and AC.

That belt doesn't need replacement. Its still good, small minor cracks like that are fine and normal when belts get used around 6 months is when they start to show up like that. Its when your missing chunks of it, thats when you worry. Or when you get squeeks, squeeks means lost of traction.

If you do replace, do both at the same time. I find the PS belt, the smaller and inner belt to wear first VS the AC belt. Gates belts should be about $24 for the AC and $15 for the PS belt. Nice quick job on a RWD/AWD mounted engine. A little tough on FWD based VQ because you have the frame in your way
