    I thought the 4AC had one of those thin V shaped belts and not the multi vvvvv like the 4AG?? Which would mean the pulleys are nothing alike.

    Someone will confirm or deny this.

    Correct

    4AC = small V pulley

    4AG = fat ribbed bulley

    if your talking about the timing belt gear then yes they are the same, if your talking about the harmonic balancer pulley then no.... see previous post.

    Ahhhhhhh correct me if i am wrong .......But i thing the 4ac has different teeth on the gear.

    4AC= square teeth
    4AG= rounded teeth.

    This is just off the top of my head from memory so i could be wrong------- But i dont think i am

    4AF 89 to 95 is square tooth and 4AF 95 to 2000 is round . Round tooth is the go , belts last twice as long. A typical round tooth belt will last 10 years with just about unlimited KLM on it . Ive seen 300000klm and never been changed , of course i wouldnt recomend it .
