If the coolant was low, it had to go somewhere. If you saw a drip, that is where you need to look further. External leaks are usually the least expensive to repair. A pressure test may make the leak easier to find. You might be able to borrow a tester from an auto parts store that rents or borrows tools. If the leak is too slow to find that way, you can add a small bottle of dark purple dye to the coolant, then check a day or two later with a black light. The dye will show up as a bright yellow stain that you can follow back to the source. Auto parts stores will have the dye, and they should have a black light too.
