I flushed my AT when I replaced my rad but without doing that, I wouldn't have lost much fluid out of those lines. I recommend draining the block when you replace the rad so that everything is new. The plug is not hard to find on my car but yours may be different. Mine is located right under the oil filter. I don't know how much the rad is from fcp but you might want to check out NAPA if you've got one near you. They were asking just over $100 for an all metal Modine radiator for your car when I called the local store. If I recall, they were at least $30-40 less than their closest competitor.
