The chambers inside the radiator can end up leaking which is a problem for many Nissan owners for certain models and year ranges. It could be from metal fatigue, corrosion, or outside damage sustained in a front end impact.

You should know that this occurrence is rare and the vast majority of factory coolers that are inside of the radiator never have problems.
