There's two ways to find the source of a leak. One is to use a cooling system pressure tester, then look for the leak. The other is to add a small bottle of dye, drive the car for a few miles or days, then search with a black light. The dye will show up as a bright yellow stain. Don't forget to check the tail pipe.
