'06 M272 v6 Water pump replacement?
Been looking everywhere for instructions on how to replace a water pump on the M272 engines with no luck. Had a noise from the engine and thought it was faulty idler pulleys but after replacing both, the rattling sound is still there and I'm pretty sure it's the water pump as the pulley on it had a lot of play when I had the belt off.
Would love to replace myself but could use some step by step instructions since there is so much crap that has to come off to get to the pump itself. Anyone done this yet? My '06 C230 just turned 125k so it's probably due.

Water pump replacement instructions attached...
While you have the belt off, check for 'play' in the power steering pulley.

Replacing the pump is pretty easy. The hardest part is probably getting the hoses off. I found that to put them back on is even harder unless you take a piece of scotchbrite and clean up the metal ends (remove the O-ring first, replace them if you can). Then take a little white lithium grease and put it on the ends and they will pop right back in.
Just keep track of what bolts go to what parts. I put the bolts back in the parts where they go before I set them aside. Also would be a good idea to have a torque wrench handy and some lock-tite to put it back together. There are a lot of bolts holding the water pump on, and no RTV sealant, so don't try to force it off if it's not coming easily.
