2002 DII had it for one week. Ichecked the coolant level when I got it and it was low. I poured a tad in and noticed it was pouring onto my garage floor from the overflow tube that juts out of the overflow tank. Anyone have a good set up for a catch tank? I would rather not just dump overflow onto the ground of my garage if I can help it.

there is really no way to catch the overflow. make sure you don't fill it passed the fill line. coolant needs to expand when it gets not. if you over fill it, it will pour out everywhere.are you filling it often? don't over fill. make sure your usingDexcool only.

You will learn with time that you do not mess or try to change thte coolant system in a Rover, it can cost you an engine.
That being said, remove the coolant bottle and replace the leaking tube or hose.
When done you can then fill the bottle to the top and over the next day or two it will seek it's on level.
