Water Pump May Develop Coolant Leak on BMW 330Ci

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.

my water pump broke but engine did not overheat keep eye on temperature at all times!!
Replace fan clutch at the same time since it will fail and it is impossible to seperate these even with the tools which will fail first. Also the tool costs almost as much as a water pump which is only 30 to 50 bucks
