can anyone point me at a how to for replacing the radiator on my 02 A4 1.8T quattro, automatic?

Also, I'm having a hell of a time picking the correct part - I found several oem radiators on several sites, some say with oil cooler, some say without, some with ps cooler, some without....
Which am I after, how do I pick the right one?

Help!

 

Apparently no one on this forum has ever replaced a B6 radiator. I can see your post has been waiting 3 years. I posted a similar question a few days ago, but I will look for help elsewhere. I have seen how the radiator comes out during a timing belt change, but no one can tell me if all that is required just for the radiator. I replaced both radiators on my 1991 80, and although not a picnic, I was able to do it without removing the bumper.
