For clarification my model uses the 70-amp alternator, which is what they quoted me the price for... Without installation. However, I found another Mercedes parts shop whose owner is actually the father of a kid I went to high school with, so he gave me a badass deal on a Bosch-rebuilt 70-amp alternator (packaged and everything, looks brand new): $195. Hell yes.

Now, the new problem... I'm trying to figure out a way to release the belt tensioner. I called my uncle and he said I have to remove the engine fan first, but unfortunately, that apparently requires special tools. Has anyone ever removed the fan without using the Mercedes tools? How would you recommend going about changing out the alternator? I'll take any advice I can get... I might need to start a new thread for this one.
