Started the car yesterday to go to work and there was a sound like a washing machine coming from the engine. Opened the hood and noticed the water pump pulley was wobbly. Shutdown the engine, and I can move the pulley up and down. No coolant leaks yet. It seems my water pump is dying.

Has anyone posted pics/instructions of the water pump replacement process on the M103 engine? I did a search. I was able to find detailed instructions for the 560 in the DIY area, but not instructions on the M103 (300SE).

In addition, I would appreciate if you can post a complete list of the parts that I should replace.
