If the leak happens only during cold nights, it could be the o-ring at the water pump's connecting tube into the block. Check for dried white residues left by the coolant in that area.
My car (96 9000CS, 90k miles) has this problem, which was caused by this "obviously flimsy" o-ring. It shrinks enough during the cold-nights to let out some coolant.
I was about to change it (naturally, changing the water pump as well. having already purchased a Hepu pump). But, after reading the board, I am not sure if that is a good idea anymore. Nowadays, I just watch the coolant level like a hawk and bring some coolant along on long trips.
It is one of those things that we learned to live with and we don't really mind for the love of our Saab's.
Good luck.
