I'm in the process of replacing my radiator on my 2001 DII but i cannot for the life of me figure out where it is being held on! I have read many places to just remove the battery box and air box and that it can be lifted out without removing the transmission lines. I just can't figure it out! Somebody please help because i have to get this done by saturday. This is where i'm currently at.

 

You must remove all the lines, trans and coolant and oil cooler lines if equipped.

Once all lines are removed then it will lift out.
It will be hard to get out because there are rubber mounts that go through to the body, if you look under the radiator you will see them, they look like a Kong Ball for you dog.
