Check to make sure you don't have a leaking freeze plug and check for headgasket leaks. What I recommend is this. First, go to a parts store and rent a pump to check the cooling system. With the engine cold, remove the rad cap, install the hand held pump, pressureize the system and check to see if you can see where the leak is coming from. If you can't, there is a dye you can put in the system. Drive the vehicle then check with a black light for leaks. The dye will glow.
