Overview

Water pumps can fail due to bearing wear, leading to leaks or noise, or impeller failure, which can cause overheating. This Graf replacement features an all-aluminum impeller for improved durability and service life.
Show original supplier description
The Graf water pump is a direct OE replacement for BMW vehicles, addressing common failure points in the factory cooling system. Stock water pumps often feature plastic impellers that are prone to failure, potentially leading to catastrophic engine overheating. Bearing wear is another common issue, resulting in coolant leaks from the weep hole or noticeable noises from the pump pulley. It also comes with a new O-ring for a proper seal. The pump is made in Italy and is of OEM quality. It is designed to replace OE numbers including 11517509985, 11517527910, and 11511433828.
