Keeping your BMW cool is of prime importance, especially with all that aluminum under your hood. Aluminum is incredibly strong and lightweight, making it perfect for performance car engines. What it doesn't do well is tolerate overheating, making your BMW water pump a critical component. If your BMW water pump decides to quit in mid-drive and your car overheats, you could be looking at a head gasket replacement or worse. So make sure you know the signs of imminent BMW water pump failure and inspect your car regularly for them. The most common way to identify a BMW water pump that's on its last legs is via leakage. Many times, a BMW water pump will have a built-in "weep hole" that allows water to leak out when it's in front of the bearing. If water is in front of the bearing, that means the seal inside the BMW water pump has failed, so the weep hole is one way that the BMW water pump can let you know it needs to be replaced. Bearing noise and, in severe instances, overheating, are two other ways to identify a bad BMW water pump.
