Just got a 96 SL600. There's a small cover at the center front of the top of the engine, with a MB symbol on it. Under it is a twist-off cap that looks like an oil fill cap. What is this for?
Looking down into it, it seems "empty". Meanwhile, the car runs rather hot even at highway speeds, and all fans running (AC on). Certainly this isn't a coolant fill point --in addition tothe overflow container??
BTW, is there a site where I can get some basic technical info until my manuals arrive?
Thanks.

 

it's for power steering oil tank.

 

Here's a link to download any owners manual.

Thanks to all. In regards to manuals, are there any other download sites besdies the owner's manuals (which are very good!)? Searched the website, but some of the links are no longer valid.
