Hello, I am Danny.

The best thing to do is use a coolant system pressure tester to find the leak. Most local auto parts stores have a tool loaner program that allows you to rent one.It then pressurizes the cooling system with the car not running a will pinpoint where the leak is coming from. I am attaching a tutorial showing you how to do it. Hope this helps and feel free to ask any questions if needed. Thanks for using 2CarPros.
