I am looking to flush the coolant and it appears that this is not a trivial task, as to get to the radiator drain plug, you have to remove the FMIC (Front Mounted Intercooler).
My questions are as follows...
1) What is the easiest way to drain the coolant... I don't need to get every drop out - I just want to get the majority of the fluid?
2) I've been told to remove the lower radiator hose.... is this the way to go or is there another method for my specific car? I've got an 81 Corvette that I work on and would have no problem doing this on that vehicle, but does anyone have a very specific picture with a very specific procedure for removing the hose where it attaches to the radiator. I didn't see any simple 80's era screw clamps. :-)
3) I do not have access to a lift and consequently I usually just jack up the right side of my Corvette, put a car ramp under the right front and right rear tires and then do the same on the left. Is there a safe way to do this on my 335i? If not, what is the prescribed method for getting all 4 wheels into the air?
Again, please accept my apologies for this admittedly novice post - I just joined the forum and this is my first.
Any and all information would be greatly appreciated and pictures are worth a 1000 words, as I am not intimately familiar with the car yet.

2007NC335i,
This should do the trick for a
DIY coolant change for the 335i.
A note about the "search" function on e90post: I have a ton more success letting google search for me and just type "e90post ___________" into google. This is how I found the link above. I recommend you try that as it was the first hit I got (after typing "e90 335i coolant flush").
As for the lifting procedure, you really should get a floor jack to lift the center lift points and put either jack stands or ramps in. You can do both the front then the rears that way. Less torsional stress on the car (it can probably take what you are describing but this method is much easier). Some people actually have to jack up the side of the car to be able to access the center lift point (I do) so 2 jacks are needed. Or, you could just use one jack and put a ramp/jack stand on the side of the car, then access the center lift point with your regular floor jack (you have one of those right???).
Good luck.
