I know this is an old post but I also just had a similar issue. Noticed a lot of coolant running down the back of the engine, enough to leak out the garage door. After looking as best as I could I decided it was most likely a manifold gasket leak. Ordered the new gasket as well as new hoses and thermostat just to replace while it was going to be apart. Well next night was in engine compartment doing something else and leaned in and rested my hand on the top radiator hose at interface with block and SURPRISE the clamp was loose and that was the leak. It was leaking from the bottom of hose onto the valley pan under the manifold to the rear of engine. A quick couple of twists to tighten the clamp saved me the job of pulling manifold. Still plan on replacing hoses and thermostat.
