Engine question help.
Hello all.
I have a 2000 S500 220 engine and while checking the fluid levels today I heard a funny sound coming from one of the pullies. Its the one in the pic with the arrow pointing at it. Can anyone plesase tell me wat this pulley is for? I never heard the little "knock"sound it makes before while I was checking the fluids. I can move it about a 8th of a inch to hear it when the engine is off. With the engine running it "wobbles" a little.
Thanks in advance.

pulley can be swapped. Thermostat might be a good idea, but if you aren't overheating i wouldn't spend the cash. Maybe check the hoses to make sure they aren't bulged and whatnot. obviously flush the cooling system

Advanced Auto and Autozone sells that water pump..I'd do a thermostat also and check the hoses like Oliver said.. The Flush will happen by itself when you change the water pump.. ( don't use the old fluids...)
Be sure to get that changed as soon as possible... It will come apart on you when you least expect it and make a mess if you don't.

I'm not sure I would trust an autozone pump. If I go with part store parts, I tend to prefer Napa, as the quality appears to be the most consistent.
I also think that there is more to flushing the cooling system than pulling the pump, as its not the lowest point in the system, therefore, there is still a bunch of coolant in the block.
cheers.
