OK, I put off replacing it and now it's rattling like crazy. Gotta change it this weekend. Do I need to remove the radiator or fan to gain access? Any thing else that has to come off? It looks faily straight forward. Oh, anybody know what type of socket I need? The bolts look like some kind of star or torx pattern. And I've been told that Zerex G-05 coolant is approved. Any thoughts? Thanks.

Torx. Buy a set for the others you will find on the car.

If you have a larger pulley that will need to be pulled as it blocks removal.

Rad stays. Fan clips off but I dont think it needs removing. Have you ever taken belts off before??

I've removed the serpentine belt off my old 302 Mustang, but not the Benz. Shouldn't be that hard. Thanks for the help mate.

be sure to put a little thread sealer on all the bolts before replacing. the service manual has the specific ones to seal up but I was like eh, screw it, and did all of them. :)

Pump failed before I could get Torx sockets, so Vaughn Motorwerks got my $280 for labor and genuine Mercedes antifreeze. Maybe next time I'll do it. Thanks Bazzle and rasoul for your input.
