Usually, the early stages of a radiator leak will only see a small amount of discoloured water drip from the radiator. This comes as a result from significant corrosion or rusting inside the radiator creating tiny holes.
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. Check out our extensive leaky radiator guide for more expert advice.
