Simplest way is to top off the coolant system, start the engine and let it warm up to operating temperature and open the hood and or get under the car to see where the leak is. Another way is to pressurize the system using a tool like this....http://www.usatoolwarehouse.com/usatoolwarehouse/OTC-7991.html

Yes. We can't help you until you locate the leak. Idling in one spot should allow you to norrow down the search and locate it, Start with the rad and rad hoses. Check the water pump seal. Check the smaller hoses, heater hoses, etc. Last intake manifolds or frost plugs in the block. Narrow it down then we can help.
