Chevrolet: heater core, heater core, diy project

Question
when i go i see water coming from the heater core.what do this mean?

Answer
Joseph,
      It means that your heater core is bad and needs to be replaced. They are designed to leak when they go bad, so it will keep leaking until it gets fixed. Depending on your year make and model of car, it can be a fairly easy DIY project.
