Purchased 03 DeVille about six months ago, only had 60k. I have drove the car 5k, runs and drives great, in the last month it has started leaking coolant, not much, but it will finally be enough for the low coolant light to come on. It does not seem to leak when driving. I can drive a hundred miles look under car nothing leaking, but when it sits in the drive overnight there will be a small spot under the car, looking from the front of the car the spot is to the right of center about a couple feet back. Any help would be appreciated. Thanks

Well time to pop the hood and take a good flashlight and see whats what... Pure speculation other than that. Bet its easy to find leaking that bad.

Rent a cooling system pressure test kit (most parts stores).

And find it fast before you be like mister "My engine blew up today" .

Drivers side could be a WP, WP cover, crossover manifold aka WP housing, heater pipe connections to the crossover.
