I have a −15% reduction pulley on my 04 MCS, I'm about to go to NAPA to grab a belt before I replace my belt tensioner.

What size should i get??

Thanks in advance.

 

Napa 060535 belt on a 15% pullied car is the way to go---

 

Thanks, got it. The last belt I bought was from Outmotoring.com and they sent me a 060539 which squeeked like hell. The only option they had was "stock or −15%" when shopping for belts. Typically they don't do me wrong though.
