Started to change my coolant today on the 560SL and didn't get too far. I can't figure out which bolt(s) are for the block drains. On the passenger side I thought at first that it was bolt #3, but it is not only not accessible, but there isn't a similar one on the driver's side. Then I figured that maybe it was bolt #1, but I removed it and it is covered in engine oil and no coolant came out, so obviously that's not it either. That leads me to bolt number 2. It takes an allen socket and there is a similar one on the driver's side. Is that it or am I looking in the wrong place? The manual says it is just forward of the engine mount and that's where I am I think.

Thanks.
