Engine Cooling problem
2003 Cadillac STS V8 Two Wheel Drive Automatic 28000 miles

Upon backing my car out of the garage and idling for a couple of minutes, I notice a large pool of antifreeze. It does not leak otherwise. What could be causing this?

This vehicle is prone to have leaking water pumps. However to properly diagnosis this you would have to pressure test the cooling system. Could be as simple as a loose hose
