Water Pump May Develop Coolant Leak on BMW 325Ci

The low coolant light may illuminate and/or the engine may overheat as a result of a coolant leak from the water pump. The leaking pump will require replacement and the entire cooling system should be inspected for leaks as it is not uncommon to find multiple leaks on higher mileage vehicles.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

I noticed my coolant level light on and saw that the coolant leaked out over time. I replaced the water pump. These issues they are discussing are all happening to my vehicle after the 93,000 mile mark.
