Coolent Leak HELP PLEASE

Help! I have a 97 Camero 3800 with a coolant leak I cannot find.
I thought it was the water pump, so I changed that and the hoses. Now I still have a leak that looks like it orignates below the thermostate housing. It is not the sending unit under the throttle body. I have a Haynes book, but it is not very descriptive of where any plugs woould be.
I have checked the freeze plugs and they look good. I am sure the leak is from the front of the engine.
HELP PLEASE!!!

How does your heat work?. Sounds like its leaking around the heater core hoses/lines. Those lines often leak when there is a clog in the system or after a while the rubber starts to wear out.

I have checked around the heater hoses. Dry as a bone . when there is water in the system it works great. The leak is somewhere in the front. Is there engine draine plug I cannot find?

is there anywhere where you can see the coolant leaking from? like residue? if not, it may be from your radiator too.. i had a crack on my radiator on my 3g camaro and it didnt show residue at all..

Get one of the coolant leak detector kits that consist of flourecent dye that is added to the coolant (harmless) and a black light. Clean off the engine and all places coolant could be leaking from. Put the dye in the radiator and drive the car around for a while so it gets hot and coolant circulates through the system. Pull the car in the garage and pop the hood. Turn off the lights (garage lights) and use the black light under the hood to look for any places that are now glowing.
