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.

  • Visitor,

    I had water pump and coolant reservoir replaced but it still leaks antifreeze periodically. Is this possibly also the reason my AC/heater doesnt blow anymore now?

    Actually, my water pump wasn't pumping enough fluid to cool the engine.. I replaced the pump, and found the impeller was plastic, and had broken loose from the shaft. Not long after that I began getting low coolant warning, and had to replace the expansion tank, due to leaking. Evidently these are known issues for the 325i.
