The BMW water pump is a crucial component in the engine cooling system of your vehicle. The efficiency of the engine cooling system depends upon the circulation of a liquid coolant through the engine to reduce the temperature as it operates, pumped through by the BMW water pump, which then sends the coolant through the system to the radiator. The radiator then removes the heat that the coolant has collected from the engine, as it travels through the radiator cooling cores, with a flow of cool air, so that it is able to repeat the process efficiently, returning to the engine cooled and ready to collect engine heat again. This process continues to repeat as long as the engine is in operation to prevent engine overheating. The BMW water pump is responsible for keeping a constant pressurized flow of coolant moving through the system. The BMW water pump is a reliable and efficient vehicle component that will continue to perform its function for many miles of travel in a well-maintained cooling system. However, if the cooling system is not maintained properly the BMW water pump can be compromised by corrosion and debris that can collect in the system. Over time, the BMW water pump can fail from simple wear and tear even in a perfectly maintained system. If you hear noises from the BMW water pump, or the temperature gauge begins to creep upwards during normal driving, these are often signs of a failing BMW water pump.
