Only difference in my case was, I had to change part number 12 shown in ur diagram because when the expansion tank thermostat disintegrated;half of it stayed in there. During the process of removing it, the 12 part started to fall apart literally it was so brittle... So the one couple hr job became 4 day because I had to order the part and wait til I get it. At the end, it felt good driving a car that has one less thing that leaks lol....

This exactly what has happened today to me on the same model. I am having a heck of a time getting the mounting plate off the radiator. Do I have to remove the radiator as well? Thanks for any help.

No you dont need to remove the mounting plate off... I think there are one or 2 screws and a clip that holds the bracket to the radiator. Once u have all the screw and clips removed, push the bracket off the radiator (towards the engine) and not up.. Check the diagram to see how the bracket connects to the radiator.
Good luck

Thank you. I found the two screws and clip. I suppose I also have to remove the transmission cooler?

On the e46 with the same engine you would. So it makes sense that you would have to detach it on the X. I would have replace the orings as well. They are around 5.00 each or so at the dealer and I think you need 3 total.

See post 35 and do what you feel is appropriate:
Issue with Behr Radiators - Page 2 - E46Fanatics

I assume you have an automatic.

Thank you. I got the BMW 5346 tool to help me remove the lines from the transmission cooler. The top line comes out with no issues using this tool. I am thinking wow this was the best $35 I've spent. I get under the car and put it on the bottom line. No such luck. It appears this hose connector isn't operating properly at all. I am afraid to use too much force because I don't want to damage it. Anybody have any experience with that? Thanks

I am not sure what the BMW tool is for. You remove the cooler from the bracket... DO NOT Disconnect the hoses from the cooler, you could drain your ATF.. In the diagram below, you pull on clip 13 up and then pry with a long screw driver to remove it. The full assembly will come out at 12 (circled in red)
