Hey u guys see if u could help me out, a few months ago i bought some under drive pulleys from bbk and ever since in the morning when i turn on the car and its cold it made a squeaky noise and when it would warm up it stopped and that would happen every day so i toke it to a mechanic shop to see what was wrong with that and they told me that the belt was kind of loose and that might be causing the problem so i replaced the belt with a smaller number and the noise stooped but now i got another problem it wasn't even been a month with that belt and its ripping from the side, facing the inside of the car so i called bbk to see if there is a specific number belt i need to put on after putting udp and they told me that no it take the stock belt from the stock pulleys i told them the problem i was having and they said it might be my tentioner from the beginning and it might of gone bad cause it taked the same stock belt, that i shouldn't have gone with a smaller belt. What do u guys think are they right or what might be wrong cause i don't want to be changing parts that i don't need to like my stock belt if u guys could help me out with these i would gradely appreciated and if u guys could help me out ASAP before the belt completely rips and leaves me stranded. Thank You very much guys.
