Yes. Right on top, behind the pump I believe. Havnt messed with a magnum in a while. Should look like a flange with a radiator hose running into the top of it, two bolts, one on each side of the flange. I doubt its the problem, just worth a once over.
Could be a hose of some sort leaking as said above. Also worth a once over of the hoses.
If your certain that its only leaking when its not running, then that to me says probably not a gasket problem. Though i dont know how you could be completely certain its not leaking when running, unless you watch while its idling.
That being said, It could still be the water pump. I have heard of water pumps leaking through the weep hole when not running. Never personally seen it, just heard of it so take that with a grain of salt.
Shouldnt be all that hard to track down a coolant leak though. Crawl under her and start looking and feeling around.
