These are the upper and lower cooler lines.



Basically how I did it was put a wood block on the oil pan, jack the engine up a bit,


Disconnect the engine shock, (with help of a vice grip, otherwise it'll just spin)

Then the engine mounts (may want to replace if broken, etc) with a hex set.


Then disconnect the bar the the engine connects with the shock, there is 4 big bolts circled in the pic on the engine block.

I suppose you can do this without doing this, but I couldn't. the twisted oil cooler line is hard to slide into the engine with this bar in place.

Then just slide them in, it's like a Chinese puzzle, remember to curse the Germans at least once.

Edit: as of today the line to the lower connection on the cooler unit is $105 (not both lines) from MB at http://mbwholesalepartsonline.aiprx.com/?teng=go&geng=mbautopart&aeng=1 this site gives 20% off Mercedes list and charges ZERO for shipping in the usa. Super slick.
