Water Pump Help
 

Hello All,
Just got me a really good deal on my first MB. It's a C280. It has 62,000 miles and it's nice and clean. The only issue I know of is the water pump has a leak. Anti freeze on the garage floor and in a small puddle right below the water pump on the engine! It looks like a little cup?
I never worked on one and the seller told me about it, so I wanted to see if anyone has any tips for replacing it. I can certainly take it apart, but any info would be appreciated. Would putting in some stop leak be worth a shot first or is that too stupid? LOL
Thanks in advance, Dominic

dont put stop leak in at all. that can just clog your cooling system.
