squeeking belt
so i got my 2000 ws6 a little while ago and its been running great.. ive put 1500 miles on it since ive owned it and this week i started hearing a squeeking noise coming from the engine bay.. to troubleshoot i put the car in neutral and revved it and the squeeking got worse with the higher rpms.. and i figured out it was the belt. at idle it barely squeaks but the moment i give it any gas it begins to squeak loudly.. the car has underdrive pulleys and an aftermarket belt that came with the car. i have not had any problems like this since i got the car.. the noise sounds like it could be coming from the tensioner but im not sure.. what would cause the belt to squeak and what is a possible solution. is there a possibility that a change in temperature would cause the belt to shrink/expand enough to make it squeak? any help would be appreciated. thanks

spray the belt with silicone spray if the noise goes away=bad belt if not troubleshoot further down the line,tensioner/pulley. it could also be your a/c compressor clutch.

The tensioner is supposed to move. If it doesn't, then the whole assembly is bad. You're concerned with the bearing in the guide roller on the tensioner, which is why I said to check it with a stethoscope.

silicon spray ftw! im guessing the recent change in temperature caused the belt to expand or shrink.. 4.26 from autozone for some liquid wrench and the job was done.. 30 mins of driving and 30 seconds of work to fix a small annoying problem. thanks for the help guys and im glad it was something minor

Sadly I had this problem about a month ago. I always heard squealing. No matter how much belt dressing I sprayed, it always came back... Replaced my tensioner.. better, but still squealing. Noticed my belt wasn't in the best shape (actually noticed the metal showing on the inside of the ribs), replaced the belt. WAY better, but still a TINY squeal... Replaced my AC lower belt.. Now it's silent as can be. All you hear is the cam
I feel dumb for not replacing the belts first, but hey I've got a new tensioner and it looks good in the engine bay.
