Did some more on the Benz today. New belt, new tension adjuster( man that was a PITA), cleaned front of the motor (turns out that it's not black under there LOL), and a quick oil change. Also looked into fixing the tear in the rear roof.. Found an arrow up there... What else is hidden is this car? LOL

I also was wondering how to test the AC compressor real quick. Is there a way to get the compressor to spin under the hood as a quick test? Just want to know before I go on Thanks

I have another question however, what is the piece mounted to the exhaust? My guess is smog??
