01 TJ, 4.0L - Leaking Coolant

I was driving down the Freeway, got off at my exit, and at my first stop light engine overheated. I filled w/ water and got home w/out engine running hot. Put it in the garage this morning, refilled radiator w/ water and let run for a couple of minutes. Coolant is pooling at the front, bottom of block.

Can someone help me diagnose where the coolant is leaking from?

The top candidates would be the water pump shaft seal, water pump gasket and thermostat housing gasket.

Some parts stores will lend a pressure tester. That usually make easy work of finding a leak.

Look under the engine for leaks at the water pump, seams on the radiator and also look at the lower radiator hose.
