i have found that a little bit of loss seems to be normal, especially in
the warmer months. i'm in alabama, and the summer months here seem to
speed the loss. but a whole refill tank in less than a week?? that's too
much, i think. i'd start looking at all the hose connections ... for any
loose clamps. as the hoses get old, they don't flex as much or as quickly
as before, and they'll start seeping/weeping, and it won't show up as a
drip/puddle on the pavement. you'll have to LOOK at the clamp to see it.
and, yes, you can lose a LOT of coolant that way.

also look at the top of the coolant tank itself. sometimes the coolant
level sensor gasket dries out and cracks, and some coolant will ooze out
here and evaporate.

and last but not least, check the coolant tank ... mine has cracked twice
in 130,000 miles. $40 for a new one (be sure to get a new o-ring/gasket
for the level sensor). you can usually see stuff that looks like birdshit
on the metal area below the tank ... that's dried coolant. :) that metal
is a muffler shield and gets rather hot, so it dries the coolant before
it hits the ground.

good luck!
