Coolant leak

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If you've replaced the radiator and thermostat and still have a heavy coolant leak near the overflow reservoir, you might be looking at a pressure issue. It’s possible the radiator cap isn’t releasing pressure properly, which can push coolant out. Another potential cause is a clogged or faulty hose between the radiator and reservoir or even a bad water pump that’s overworking the cooling system. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
