Well, it sounds to me like you have a heater hose thats bad. When you say left do you mean sitting in the vehicle or standing in front? I think you mean the passenger side and if it's what I think you will have water running down on the exhaust on that side.
Chase the hose and if it goes to the firewall it's your heater hose. Shoul be a pretty easy change out, just lose some anti-freeze in the process.
Hope this helps.?
