Smoking due to green fluid everywhere under the hood, why?

Hi,

If the fluid was green, it sounds like antifreeze. That would also explain why you had no heat. Do me a favor. Look through this link and let me know if it helps. Check radiator hoses and heater hoses. Something may have been cut or disconnected when the work was done.

Let me know what you find or if you have other questions.

Take care and God Bless,

Hello, I'm Danny.

The green fluid is engine coolant. It's possible that when the shop installed your new starter they disconnected or failed to reconnect a coolant or heater hose resulting in the leak. It's also possible that they could have damaged a coolant hose while performing this repair. I would definitely take the car back to them to inspect their work see if it is covered under their warranty. If they refuse to cover under warranty or you are not going back to them I would suggest to perform a cooling system pressure test. You do this with the car cold and engine off to prevent injury. It's basically a pump that pressurizes the cooling system and then you can visually see where the leak is coming from. Here is a tutorial showing what is involved with a cooling system pressure test:
