@ajmendez1975 could be a leaking hose or a leaking radiator. We really need to see where you are looking it and see if we can guide you further. The best test would be a pressure test. Not sure where you are located so it'll be kind of useless to tell you a store where you can get them from. Just do an online search for Radiator Pressure tester and see if that is something you want to invest in. If not, some radiator places will do this for you, but may charge you.
