Where is the coolant drain plug? Found a few drops of coolant this Morning ! Where else could it come from?

Check the radiator hoses, radiator, around thermostat, freeze plugs, heater core hoses. The drain is on the bottom of the radiator on the driver's side. Also, if you can, get a pressure tester at a parts store. Most will lend them to you. With the engine cold, remove the radiator cap, screw on the hand held pump, and pressurize the system. Check for leaks when under pressure. It there is a leak, that is when you will find it.

Could be a leaking heater hose, radiator, radiator hoses, freeze plugs and water pump-pressure test the cooling system-
