I have a 98 Chevy Cavalier LS and it was leaking antifreeze but it wasn't coming from my radiator or hoses on the top side. I got to looking at it and found the leak. It's dripping from the hose on the back firewall. I'm guessing it's the heater hose. But the hose looks only like an elbow, there's no other piece. So where does the hose connect to on the motor? Help please 🥺
