loud squeeling noise - not belt

When i get in my car in the morning and start driving theres a high pitched squeel coming from the front passenger side of the car. Any ideas of what this could be? It only happens in the winter when the car is cold. No more squeel once it warms up. It usually happens when i am driving but today i noticed it while sitting at a stop light. HELP!

why do you think its not the belt? does the sound change with RPM change? year/model/mileage?

that happened to me when i needed a new tensioner, it was the belt but it only happened when the car was cold

It is a loud squeel noise. Just like metal rubbing on metal. Its more high pitched then a squeeling belt. I have a 94 SL2 with 91k miles. The squeeling dies down in higher RPMs but does not go away until the car warms up.

Hey bro that ear drum-piercing screech is most definitley your belt tensioner. They usually go at around 100k miles on these s-series engines. I had to replace mine recently and got the part from an Advance auto parts store for like $30 I believe.

mine just started the same thing yesterday and then to day went n continously got out to check and the idler pulley is out of place does anyone know if this part is hard to replace found the part at napa for 28 bucks but have never replaced one before

how strange... i think i have the same noise but i'm almost sure its the belt
