You are very welcome. I just hope I can help. As far as the spraying, if it is behind the water pump pulley, chances are it is the pump. There is a weep hole that can leak when the bearing or seal in the pump fails. If possible, take a pic and upload it for me to see the location of the leak.
As far as the heater core, I attached the parts and labor for it. Note that the part price is for an OEM part. You can get one aftermarket for less. However, the labor hours remain the same. You will have to take the average labor rate where you are and multiply it times the labor hours.
The aux core is for rear heat and wouldn't be leaking from the front, so focus only on the one that says main heater.
Let me know if this helps. Also, if you want to replace the pump yourself and feel you can do it, let me know.
