BMW 128i Water Pumps

Like all vehicles, your BMW 128i has a water pump. It's crucial to your engine's operation. What it does is simple: it moves water back and forth from the radiator to the engine, ensuring that your engine runs at an optimal temperature. It's one part – though an essential one – of the general cooling process that keeps your car's engine from overheating.

How a Water Pump Works

The water pump is powered by a belt that connects to your crankshaft. When the pump's axle turns, it generates suction that draws water from your radiator. The water is driven against the pump's outer walls by centrifugal forces, and then drains into the engine block and passes through the cylinder heads. Once that's done, the water returns to the radiator to cool down and repeat the process all over again.

How to Spot a Failing Water Pump

Unfortunately, even the best water pump can go bad over time. That's not good, since it leaves your engine at risk of overheating and developing serious problems. Signs of trouble include:

• The high temperature warning indicator lights up
• Your low coolant dash light comes on
• Coolant leaks
• A loose water pump pulley
• You hear deep, grinding noises from your engine
