Engine Water Pump

The Geba 11517527799 is a metal engine water pump, a common replacement part for BMW vehicles, particularly those with M52 and M54 engines. This component is responsible for circulating coolant through the engine to prevent overheating. A failure in the water pump can manifest as a coolant leak through the weep hole, play at the water pump pulley shaft, squeaking noises, or engine overheating conditions. This water pump is designed for a wide range of BMW models, including the 3 Series (E36, E46), 5 Series (E34, E39), and Z3 (E36), covering model years from 1990 to 2010. It is specified for engines producing between 136-231 horsepower (100-170 kW). The driven units include the water pump itself, alternator, and power steering pump, with a total length of 1560mm. When replacing the water pump, it is recommended to check the state of the automatic coupling bearing for clearance. Additionally, the product comes with a new O-ring. For specific installation guidance, refer to resources like the "How to Replace a Water Pump on an E39 BMW 5-Series (6-cylinder)" guide. The Genuine BMW version of this part is known to feature a plastic resin impeller, which is a common failure point on higher-mileage engines, unlike some aftermarket replacements that may feature metal impellers. As an "Engine Water Pump," it is a direct replacement for OEM part numbers such as 11517527799, 11517504040, and others listed. It is a key component in preventing catastrophic engine failure due to overheating.
