how long can I drive with a cracked radiator? It drips slowly

What is your question?

my jeep was running hot on and off, finally figured out it was the fan, as the mechanic was testing the fan antifreeze came from the front left side area near the lights, we are trying the process of elimination praying its not cracked. He replaced the top radiator hose, but this morning after parking, I noticed the drip again. How much should it cost to be replaced, how long it takes and more importantly how long can I ride with a cracked radiator.
