Antifreeze leak in my 1990 Subaru Legacy Wagon 2.2

Good afternoon guys. Have a question. I just changed The thermostat and the radiator hoses on my Subaru. Everything is tight. For some reason, I can run to the store and come back home and park. The following morning there is a dinner plate size of antifreeze underneath the right front of the car. Overflow is on the driver's side so it is not coming from there. The head gasket is not leaking. The hoses are all tight and the thermostat housing is tight. The temperature gauge is normal. It is not overheating. It is driving me nuts any suggestions? Thank You in advance. Bob

Have the cooling system pressure tested, that's how a leak can be found.
