First, remove the cover so you can get a better look at where the problem may be coming from. If you still can't locate it, you need to pressurize the cooling system when the engine is cold so you can locate the leak. Basically, you pump pressure into the system. Most parts stores will lend or rent the tool to you.
Check it that way and let me know what you find.
