Guys , i want to replace the belt of my car. ive done about 10k miles since i bought it, and just to be sure i want to cxhange the belt. I went to pepboys and they asked me if is a a/c or not a/c cable. What does this mean? Where can i find what the engine belt is. Btw i have a focus zx3 2001,, l2.0 zetec. Also, is there anyway i can change it by myself? Thanks CHEERS[drinking]
