Hello, I'm planning to change my water pump on my E320, standard engine. Not CDI. I have 150,000 on it and the pump failed on me.
My question is which pump do I buy?
When I look up the part on various retail websites such as RockAuto.com, they list 2 different pumps for the same year... one has 2 hose fitting and the other has 3 hose fittings. So I'm not sure which one I need. Any suggestions?
Pumps should come with the gaskets correct? I don't need to buy gaskets separately, correct?

Just wondering what else you all recommend changing out at the same time.
Such as tension pulley, idle pulley, serpentine belt, thermostat, radiator hoses, and MB coolant.
Thanks

Your pump is 112 200 15 01 and no substitutes.(also available from MB as a rebuilt)

The pump has three water connections and uses seven repeat seven different type of bolts---Therefore attention to detail is important or we will hear whining about leaks. The part comes with the gasket(DO NOT USE GASKET SEALER)

If you have never done this before, I strongly advise you spend the eighteen bucks and get a 24 hour subscription to MB WIS and find document AR2010P1271R ---that's the water pump removal document with all the carefully laid out steps, torque requirements bla bla.

I would also inspect all my belts an pulleys and tensioning devices.
