One of the most common causes is from a crack in the radiator. The radiator will usually leak antifreeze before the coolant hoses or hose connections begin leaking during the life of a car.

If you don't see evidence of a coolant leak on the exterior of the engine and cooling system or on the ground below the engine, the leak could be internal. This could be costly if allowed to continue. Have the system pressure tested and repaired asap.
