Why could my coolant be leaking out like a waterfall after filling it ?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! In the immortal words of TLC, "Don't go chasing waterfalls!" There's a host of reasons coolant could be flowing like Niagra. It could be a busted radiator or a blockage forcing it out of the reservoir or the radiator cap. It could be a ruptured hose or any number of things. The best thing to do is avoid driving it!
