Welcome, I'm Chris (aka Moose). I'm here to help 365 days a year, but not every hour of the day. I try to prevent delays as much as possible. Please understand I am not there and can only advise based on what you tell me. Let's get started.

The fact that when running hot there is no heat means the water pump is not moving enough coolant or there is a head gasket issue that is allowing air to be packed into the cooling system. Since you also have noticed an external leak. A cooling system pressurizing pump would help find that leak due to it being able to max out the pressure which would show you a stream of coolant spraying out.
