Chevrolet Repair: Antifreez leakage., intake manifold gasket, chevy malibu

Question
I have a 3.1L v6 chevy malibu 1997 and it is constantly losing antifreez. We now this because the antifreez level in the tank keeps dropping and the coolent light goes on in the dash when antifreez goes to critical level. The antfreez is not going into the oil tank and there is no smell of antifreez inside the car, there is no leaking stains on the drive way. Probebly it is leaking while driving, and when engine is hot. I think the antifreez is evaporating from the hot serface of the engine, I think that is because there is no stain on the drive way. Can you tell me where the antifreez is leaking from? can it be a punctured hose or a leaking gasket? Can you name all the reasons if possible? (Thankyou for your time I realy appreciate it)  

Answer
Most likely what you have is a head gasket(s) leak between the engines coolant chambers and the engines combustion chambers thus it to being burned and expelled thru the exhaust system. This can also be the case of an INTAKE MANIFOLD gasket.

A coolant PRESSURE TEST and a CYLINDER AIR PRESSURE TEST should be performed on the cooling system of which will reveal this probability.
