Hello I will help you with your question, There is a heater hose fitting in the back corner that might be leaking. This is the same manifold that has had its warranty extended due to the plastic getting brittle and cracking. Try pouring water in as you use a flashlight and mirror to find where it is coming out. I hope it is the hose but it probably is the manifold. Please let me know what you find so I can help Thank you

would coolant pour out if manifold was cause can't see leak from top of engine not a lot of space between firewall and rear of engine

It could, I have had them split enough to let a sold stream out as I pour it in the tank. A flashlight and mirror will allow you to see back there, have a helper pour in water if you need to be looking for the leak. Let me know what you find and I will see what I have as far as procedures showing the repair. Thanks
