2.0 petrol

Hello, can anyone tell me what type of serpentine belt i should buy for my 2004 mazda 6 2.0l? I am also looking for a diagram, the previous belt snapped and i couldn't read the letters/sizing nor did i see how the belt was put on. Thank you Jakob.

Hi everyone Just want a little bit of advise I have just bought myself a Mazda 6 tamura 57 plate is it worth it to turbo it or supercharge. Think it’s running at 147bhp does anyone think turbo and remap would take it to like 220? thanks for any advice Sam
