My CL55 has a squeak coming from the engine bay that I can't seem to figure out. It happens when accelerating from standstill or slow speed (e.g. traffic light), almost always around 1500-2000 rpm, and isn't correlated with shifting. It doesn't happen with hard acceleration or very slow acceleration, but happens every single time somewhere in between those two. Doesn't matter if the car is cold or warmed up. It's been there since I bought the car almost a year ago, it hasn't changed or gotten worse, but it's a bit annoying.

My first thought was belt slip, but I had both belts and the SC tensioner replaced, and that changed nothing. Any ideas?

Could be the alternator pulley.

Idler pulley…. belt tensioner…. water pump pulley…ac pulley….best thing is to remove your belt and spin all the pulley by hand clockwise and see if you can hear if it’s bad or if it feels bad when you turn it by hand….should be easy fix!! Good luck 🍀

Thanks both! Will check all of the other pulleys
