Leaks are pretty easy to diagnose. Fill the car up with fluid, start it, wait for it to warm up and watch for the leak. Use a flashlight to find the leak. You might need to remove the undertray to find the leak if it's one of the lower hoses.
If you are lucky it will just be the rad cap that has gone bad. The radiator expansion tank is one of the most common places for leaks to occur. Next are the hoses then water pump and thermostat.
