Appropriately shaped connection spigots ensure a secure fit for the hose, and the correctly chosen internal cross-section allows for proper coolant flow. Its original BMW origin means factory dimensional tolerances are maintained, minimizing the need for additional modifications during installation.

Benefits of Using an Original Connector

Using the original water pump hose connector in BMW G20, G21, G30, and G31 models helps maintain the integrity of the entire cooling system according to the manufacturer's specifications. Key benefits include:

• factory fit for the water pump and cooling hoses in the specific BMW generation,
• stable, leak-proof connection reducing the risk of fluid leaks,
• maintenance of proper flow in the cooling circuit,
• easier diagnostics and servicing due to compliance with manufacturer documentation.

For users looking to restore the proper function of the cooling system after a failure or leak, choosing such a component is a practical and technically safe way to repair.

Characteristics of a Used Part

The offered connector is a used part, sourced from disassembly, which allows for maintaining original specifications while optimizing repair costs. Such components are often chosen by workshops and individual users who prefer factory solutions over aftermarket alternatives of unknown origin. A used part retains a construction consistent with the BMW design, promoting trouble-free installation and compatibility with other cooling system components.

Assistance with Selection and Related Parts

When selecting a hose connector for a specific engine version, it is advisable to verify compatibility with the model designation and vehicle year to ensure full compatibility with the existing hose system. If necessary, you can refer to the OEM part number and interchangeable numbers visible in the product's technical specifications, which facilitates matching in service catalogs and workshop programs.
