- E350cdi Coupe 2012, R230 Sl350 2003 + CLK 320CDi ( will be putting it up for sale)
Hi, as per subject line. Took my serpentine belt off my r230 sl 350 (M112) to investigate a revs related whining noise. Discovered my P steering fluid was low so topped up and seems to have reduced it significantly. Thought I'd also check the tensioner /idler/alternator and water pump by spinning and listening and apart from slightly rattly idler wheel I found a definite squeek from the water pump. Can't find a way to embed my water pump.mp3 file to be playable within a browser but you can download the tiny 10 second mp3 file here: ( a direct link to wiki downloads site)

It's almost comical! Remember it's not as loud as the recording---my phone mic was right next to the pulley. It still seems noisy for a seal though---it isn't some kind of venting noise by any chance, I know pumps have a bleed hole. The bearing feels fine no roughness and no wobble on the shaft. What do you thinK?
