Put coolant in reservoir and it literally runs out on driver's side at rear of motor near transmission and motor meet up. Motor is not even running and it is pouring out.

Hello, I am Danny.

Usually in that area you are describing it sounds like the intake manifold gasket is leaking. The best thing is to wait for car/engine to cool down before you really start looking around. If you do not have access to a cooling system pressure tester your local auto parts stores (Pep Boys, Autozone, O'Reilly's) has a loaner program and will rent you one. Basically it goes on in place of the radiator cap and pressurizes the system. Once pressurized you will be able to see where the leak(s) are coming from. Be sure to fill with just plain water first to not waste antifreeze while looking for leak. I have attached a tutorial showing what is involved. If you feel confident in doing the repair I can attach how-to steps. Hope this helps and feel free to ask any questions if needed.Thanks for using 2CarPros.
