My 1992 Audi 100 V6 shredded its serpentine belt. I got a new one from Napa which is too long no matter how I attempt to thread it. (It's 2273 mm long.) It appears that an idler pulley is missing... There's only one pulley but my owner's manual shows two. It doesn't appear that anything has fallen off, though.
How many idlers should this thing have?
Another thing i have found is moving the alternater foward will take up some slack if its only a few inches too big. Molly the mechanic
ACTUALLY THERE IS AN UP GRADE THAT ELIMINATES ONE IDLER PULLEY, THAT WILL BE YOUR CASE CHECK ON THE DEALER ABOUT THAT....
Not quite sure how many idlers it should have, but does your car have A/C? Serpentine belts for any car that have the A/C option are sold in two different lengths, the A/C one being longer. If this is not the case, ask your NAPA parts person for the routing diagram for your vehicle. Having worked for them in the past, I know for a fact they have easy access to them. Sometimes with serpentine belts, even experienced mechanics get confused and can`t reroute it right without a diagram.
