Purpose and Function in the Cooling System

This hose belongs to the Cooling System Hoses and Pipes group and works with the auxiliary water pump in the hybrid powertrain of the BMW i3 I01 60Ah Rex with a gasoline engine. It is responsible for directing the coolant flow, which is crucial for:

• maintaining stable temperatures of the combustion and hybrid drive components,
• proper operation of the auxiliary water pump,
• reducing the risk of overheating in urban conditions and under higher loads.

Thanks to its factory fit, the hose maintains the correct fluid flow geometry, facilitating installation and minimizing stress on the system.

Benefits of Using an Original BMW Hose

Using an original hose in the BMW i3 Rex offers several practical operational benefits:

• Precise fit to factory spigots and mounts in the engine bay,
• maintaining the coolant flow path designed by the manufacturer,
• compatibility with the gasoline engine cooling system in the Range Extender version,
• reducing the risk of leaks resulting from the use of aftermarket parts with different geometries.

A used OEM part helps maintain the integrity of the entire cooling system, which is particularly important in hybrid vehicles where different fluid circuits interact.

Component Condition and Service Application

The hose is a salvaged part offered as a used OEM component. This type of part is suitable for both standard replacement of a worn hose and for repairs after a collision or intervention in the cooling system. Choosing an original, used hose is often a cost-effective solution while maintaining factory specifications.

Due to its function within the cooling system, it is recommended to have it installed by a workshop experienced with BMW hybrid vehicles, ensuring proper system bleeding after replacement.

Technical Support and Additional Materials

During the summer, the cooling system in gasoline-powered vehicles operates under particularly demanding conditions. To better understand the impact of high temperatures on cooling efficiency and potential cost savings when using used components, it is worth reading the guide Summer Heat vs. Cooling System – Used Radiators and Fans as a Way to Control Costs.
