why is the hole above the starter leaking water

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I’m sorry you’re dealing with a leak on your Grand Cherokee. The hole above the starter leaking water is likely a sign of a failed freeze plug, also known as a core plug. These plugs seal openings in the engine block that are part of the manufacturing process and can corrode or loosen over time. When you add water, it leaks out because the plug has failed, leaving an open path for coolant to escape. The good news is that freeze plugs are replaceable, though accessing them can be tricky, as they are located on the engine block. It’s essential to fix this promptly because losing coolant can lead to engine overheating. Consider having a mechanic inspect the leak to confirm the diagnosis and replace the plug if necessary. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
