Application in the BMW i3 I01 cooling system

The described electric coolant heater works with the vehicle's high-voltage system, ensuring effective heating of the cooling circuit in low-temperature conditions. In electric and hybrid cars, this is crucial for maintaining the proper operating temperature of components and for achieving cabin thermal comfort faster without excessively draining the range.

Thanks to its OEM-compliant design, this element maintains full compatibility with the factory electrical and hydraulic installation of the BMW i3 I01, which facilitates installation and reduces the risk of operational problems after replacement.

Construction and technical characteristics

As part of the Water pumps group, the electric heater is integrated into the coolant flow system, ensuring stable circulation of the medium within the required temperature ranges. The BMW OEM design includes precisely matched connection ports and electrical connectors adapted to the factory wiring harness in the i3 I01 model.

The element has dedicated part numbers and interchangeable numbers, which facilitates unambiguous identification in BMW catalogs and allows for safe matching to a specific vehicle configuration. This helps reduce the risk of installing an incorrect component and avoids communication issues with the vehicle's electronics.

Benefits of using an original BMW heater

• Full compatibility with the high-voltage system – a component designed specifically for the electrical architecture of the BMW i3 I01.
• Stable operation of the electric and hybrid drive cooling system, especially in low ambient temperatures.
• Reduction of the risk of controller errors and fault messages thanks to the use of OEM parts.
• Possibility to use existing mounts and connections, which shortens service time.
• Reasonable repair cost due to the use of a proven used part instead of an expensive replacement of unknown origin.

Condition, origin, and fitment

The offered BMW coolant heater comes from dismantling and has the status of a used original part. This type of component is particularly valued in workshops specializing in electric vehicles, where compatibility with factory electronics and controller software is key.

Before purchasing, it is worth verifying compatibility by the OEM part number or interchangeable numbers to ensure that the heater will be suitable for the specific equipment version and model year of the BMW i3 I01. This makes the installation process smoother and minimizes the risk of needing a replacement.

Support in selection and additional technical materials

When selecting cooling system elements and other power and drive control components, it is helpful to use OEM numbers and service documentation. For components working with the power supply system, it is worth familiarizing yourself with the principles of identifying parts by factory numbers and good maintenance practices – this is described in more detail in the article: Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration.
