No hot air from heater. smoke/steam wisping from behind

Customer Question

No hot air from heater. White smoke/steam wisping from behind engine block
JA: Do the vents feel cold? Is there a coolant leak?
Customer: Ambient temperature at best. There has been a coolant leak. I replaced the upper radiator hose as there was a crack. I'm unsure whether that was the only leak. Coolant still boils after running to operating temp
JA: What is the model/year of your Saturn?
Customer: 02 L300 V6
JA: Are you fixing your L300 yourself? What have you tried so far?
Customer: I'm trying to do as much myself as possible. Other than replacing the upper radiator hose and two different rubber caps on the radiator, I've just been trying to pinpoint the leak.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I think that's it. Coolant loss, boiling coolant, no heat from heater, and wisps of smoke from back of engine. I'm thinking heater core pump. But I don't know how to confirm or rule out.

Hi, My name is ***** ***** for the delay.
I will do my best to assist you.

Expert:  tims auto repair replied 6 months ago.

are you saying that you still need to add coolant and there is steam coming from the engine still?

Customer: replied 6 months ago.
I added twice as the tstat opened. But now it's just boiling. I'm getting wispy white smoke (steam?) Coming from the back of the engine block. Isn't that where the heater core pump is?
Expert:  tims auto repair replied 6 months ago.

you need to be able tolook at the rear of the engine to see where the leak is coming from...

the heater hoses are back there and may be busted..this is something you will need to look at..

Customer: replied 6 months ago.
Ok. So would you say that the heater lines and heater core pump would be a logical spot to start at in the morning? Also, what am I looking for to confirm or rule out a pump failure? Or is it more than likely a leak? Would a leak lead to no hot air from the heater?
Expert:  tims auto repair replied 6 months ago.

yes,,you need to look at the heater hoses and find that leak to fix it

Expert:  tims auto repair replied 6 months ago.

there is no other pump other than the cars water pump

Expert:  tims auto repair replied 6 months ago.

you need to fix the leak first..even if it does have other problems,you will never know until the leak is fixed

Customer: replied 6 months ago.
I have a Haynes manual for the car and it states that the car has a water pump, a heater core pump, and an auxiliary water pump. Are you sure that the water pump is the only pump?
