Coolant leak

Hello, I'm Danny.

Since you are noticing coolant drops on the ground it does sound like there is some sort of leak.First thing I suggest is to to perform a cooling system pressure test.It's basically a pump that pressurizes the system with engine not running to determine where coolant is leaking from.If you don't have access to a pressure tester most auto parts stores have a tool loaner program (depending where you live) and will rent you one.Here is a tutorial showing what is involved:

Also, have you checked to see if engine oil and coolant are mixing together in either the radiator or engine oil crankcase? That would be a separate more costly repair.Hope this helps and thanks for using 2CarPros.

Hello again.

Yes, it is possible to have leaks from the heater hose(s) A pressure test can determine where leaks come from. Is your car/SUV model the 308 or 3008? You mentioned both in your question. Thanks again for using 2CarPros.

Hello again.

The two heater hoses will be connected to the heater core tubes that run through the firewall. It will be an insulated connection in the firewall.I'm not sure if your car is a right or left hand drive car due to your location but it will always be on the firewall opposite from steering/brake controls. I've attached a picture below for reference. Not sure if correct. Hope this helps and thanks again for using 2CarPros.
