Water Pump May Develop Coolant Leak on BMW 330i

Problem Description and Possible Solution

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.

Check Coolant Level comes on often, even after a recent lube and oil. I either add water or stop by my car repair shop to add coolant but happens more often than should.
Coolant light on trying to repair for a month now keep having the same problems been to two shops now still no good
Water pump burst leaking all coolant. I am taking the car in as soon as possible to have this looked at and replaced.
