Purpose and function in the BMW i3 I01 cooling system

The presented radiator with a 350W fan has been designed specifically for the BMW i3 I01 platform, with a focus on precise powertrain temperature management. The component belongs to the Fans and fan shrouds group, responsible for forced airflow through the radiator core and maintaining a stable operating temperature under various load conditions.

Combining the radiator with an electric fan motor allows the vehicle's electronics to control the system's operation, enabling cooling optimization at low and high speeds, as well as during idling. As a result, the cooling system reacts dynamically to current thermal demand, reducing the risk of overheating and supporting the durability of other components.

Construction and functional parameters

The radiator with a 350W fan constitutes a complete cooling assembly, in which the electric fan motor with power adapted to the specifics of the BMW i3 I01 plays a key role. This configuration ensures:

• stable airflow through the radiator core under high thermal loads,
• effective cooling in urban conditions, where frequent stops require the fan to operate regardless of driving speed,
• consistency with the vehicle's factory electronic control.

The original BMW OE origin means maintaining factory geometry, mounting points, and operating characteristics, which facilitates installation and minimizes the risk of fitment issues. The assembly has been designed to work with other cooling system components and engine compartment covers in the BMW i3 I01.

Condition, origin, and benefits of using a used part

The item is offered in used condition, which allows for a favorable compromise between repair costs and maintaining original BMW quality. Choosing such a solution is particularly attractive for post-accident repairs or servicing vehicles used intensively, where both technical compliance and rational costs are important.

The original radiator with a 350W fan provides:

• factory fitment to the BMW i3 I01 construction,
• maintenance of the cooling characteristics intended by the manufacturer,
• the possibility of direct replacement of the damaged assembly without modifying the installation.

Selection, compatibility, and reference numbers

The presented radiator assembly with a fan has a dedicated OEM part number and a set of interchangeable numbers, which facilitates unambiguous identification in BMW catalogs and parts selection systems. In practice, this means that during replacement, you can precisely verify compatibility with a specific version of the BMW i3 I01 using the reference numbers assigned to this product.

For certainty of fitment, it is recommended to compare the markings from the removed part with the data in the product's technical specification and to take into account the body version and the vehicle's year of production. This approach minimizes the risk of purchasing an incorrect component and speeds up the service process.

Cooling system expansion and related BMW components

If you are planning a comprehensive repair or upgrade of the engine area in your BMW and need other elements from the same group, such as additional fans, housings, or airflow support modules, check the available parts in the BMW Fans and fan shrouds category.

To better understand how summer conditions affect the cooling system's operation and why used radiators and fans can be a cost-effective service solution, it is worth reading the guide "Summer heat vs. cooling system: used radiators and fans as a guarantee of savings", which discusses the practical aspects of operating and selecting such components.

Summary

BMW i3 I01 Radiator Engine Cooling Coolant Unit Fan Motor 350W is an original assembly from the BMW OE group, ensuring compliance with the vehicle's factory construction and predictable cooling characteristics. Using a used component allows for reduced repair costs while maintaining high quality of workmanship and fitment, which makes this product a rational choice when servicing the cooling system in a BMW i3 I01.
