Antifreeze keeps leaking out of hoses

First problem was while idle I saw steam coming from engine. I opened the hood and I noticed that the bottom hose that is connected to the engine now has 2 small holes that antifreeze leaks out car was very hot, but my gauge read normal. I took it to the show they replaced the hose. A few days later at the bust stop idled I heard pop noise then saw steam again. This time it was kind of in the area where the top hose connects to the radiator. The temperature was normal, but the engine was hot you could hear a boiling sound and a hissing sound like air. Can someone help?
