Coolant Leak

i own a 94 cavalier and i have a coolant leak idk if its a hose or something but i really dont want to keep buying more coolant for a minor reason.

I just want to know if there is a liquid or something i can put in there to either plug the hole or if im gonna have to fix it myself.

Thanks ahead of Time. :)

no type of stop leak is goning fix a hose leak. You`re going to have to get down under car and search for the leak. if no puddles are forming under car then it must be internal
