As the unwanted holes are typically miniscule to begin with, a leaking radiator doesn't immediately constitute an emergency situation. However, you should address the problem of a leaking radiator as early as possible in order to prevent the possibility of further issues.
Who should I call if my radiator is leaking?

Loss of coolant can cause your car to overheat, which can easily lead to a breakdown. This will leave you stranded and waiting for a tow truck to take you to the nearest mechanic. As bad as this scenario might sound, a coolant leak can ultimately lead to much greater problems.
