Need Help on ASP pulleys URGENT!!!
Hi, I took off my aftermarket pulleys on my C32 today and put the OEM pulleys back on. Now when i first start up the car, i will hear this squeaking noise. My tech told me it's because the larger aftermarket crank pulley stretched the belt a little bit and cause the belt to be loose around the OEM pulleys. therefore making the noise. But my belt was almost brand new as it was replaced about three weeks ago. Will three weeks on a aftermarket pulley really stretche the belt that much? Also, i thought even though the crank pulley is bigger than OEM and water pump and idler pulley are smaller. So the overall length should be the same. Is there anybody else with aftermarket pulley had this same problem when they put the OEM back on? Please help. Any info will be appreciated.
thanks
thanks

what kind of squeaks?
asp pulley should not affect the belt in anyway. they made the crank pully larger, but also made the other pulley smaller to be able to use the stock belt.

thanks for all the replys. But i remember my tensioner pulley was replaced late last year, so only about half a year ago. and with the aftermarket pulleys on, i don't have any problems. It's only today right after the OEM pulley were put on, the squeaking noise started. and it only happens when the tach goes high RPM.
So if i am only cruising around 3000rpm, there is no noise.
