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:

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

Spray the collar where it mates with the line with silicone spray, then fit the tool and wiggle it around. Should release.

You are talking about the transmission cooler being detached from the mounting plate right? I just used a screw driver to pry a little then pull.

I am replacing my radiator right now on my e46. What started as a 4 hour job has turned into a marathon it seems. Some of my hoses would not come off and I have flatted orings in some of them. So I ordered new hoses instead of chasing down the orings. At least the dealer sells the transmission cooler orings.

You don't remove the lines. You detach the cooler from the mounting plate.

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)

Thank you. I finally got the part in I was waiting for and am going to continue on this project today. Where exactly is #13 and what does it look like? I'm having a hard time finding that. Thanks for the help. I hope to post a recap of the problems I faced as a relatively inexperienced DIYer.
