Application of the BMW Gearbox Coolant Hose
The hose is part of the transmission oil cooling system in F-series BMW cars with a manual gearbox. Its function is to transport the cooling medium between the cooler and the gearbox, which allows for maintaining a stable operating temperature of the transmission during city and highway driving. Thanks to its precise geometry and factory-fitted ends, the hose works with original connectors and mounting points in the body, which facilitates service installation.
Benefits of Using an Original BMW Hose
Choosing an original gearbox coolant hose is important for both the durability and comfort of vehicle operation. The component has been designed for specific BMW models, which translates to:
- proper routing of the hose in the engine bay and undercarriage,
- correct fit with brackets and clamps,
- maintaining proper coolant flow in the system,
- reducing the risk of leaks at connections.
This allows the gearbox cooling system to operate under stable conditions, promoting smooth gear changes and reducing the thermal load on the internal components of the transmission.
Technical Characteristics and Compatibility
The hose is designed to work with a manual gearbox, which is important when selecting parts in the BMW catalog. The hose’s construction has been developed with the cooling system used in the F10, F11, F30, F31, and F36 platforms in mind, ensuring compatibility with the factory installation routing. The item has an assigned OEM part number and related replacement numbers, which facilitates compatibility verification in service catalogs and parts selection systems.
Condition, Origin, and Service Application
The offered hose comes from the BMW range and is a used part, allowing for an economical repair of the gearbox cooling system while maintaining original specifications. It serves as a replacement in case of:
- leaks from the existing hose,
- mechanical damage (cracks, abrasions, deformations),
- service replacement of transmission cooling system components.
Using an original hose from the same model group allows for maintaining the factory configuration of the cooling system, without the need for installation modifications or the use of universal solutions.
Technical Support and Additional Information
When selecting a gearbox coolant hose, it is advisable to verify the part numbers in the vehicle’s technical specification and compare the hose routing with the factory-fitted part. Information about replacement numbers assigned to this reference can also be helpful, facilitating identification in BMW catalogs and service systems.
