Hello and welcome to JustAnswer!

You could have a leaking hose, water pump, heater hose, etc, but if the leak started as the result of a front end impact then you most likely did damage the radiator. If the impact was at very low speed and there wasn't much damage then odds are nothing went further back than the radiator. The leak happening afterward could be coincidental though.

The best thing to do would be to refill the system, you can use water instead of coolant at this point since it's going to be drained for the repair anyway. Once filled if you're still unable to see the source then a pressure tester can be used to put the system under pressure with the engine off and force it to leak. If there is anything near a substantial leak then you'll be able to see the general area if not the exact location. You may need to remove some components to be able to see exactly where the leak is coming from.
