Bosch Comprehensively Expands Thermal Management Program for the Aftermarket

Karlsruhe, Germany – Bosch is significantly expanding its thermal management range for the aftermarket. With the addition of brand-new product groups and the expansion of its existing portfolio, Bosch is strengthening its position as a comprehensive system supplier for workshops. The goal is to offer businesses an even broader and deeper range of spare parts in proven Bosch quality, all from a single source, to support a growing number of repair cases involving to thermal systems.

Expansion with new product groups

The thermal management system in a vehicle ensures that all components operate within their optimal temperature range while maintaining a pleasant climate for the occupants. Building its extensive expertise in vehicle thermal systems and decades of development and manufacturing experience, Bosch will expand its existing range from the first quarter of 2027 to include radiators, oil coolers, intercoolers, and cabin heat exchangers. The new range will initially comprise of approximately 1,000 part numbers for passenger cars and light commercial vehicles in proven Bosch quality and will be successively expanded. The products are offered in various versions to meet the specific requirements of each vehicle application – for example, oil coolers with or without a filter, or radiators with or without an oil cooler – thus covering a large portion of the most common vehicles in Europe. To facilitate installation for workshops, a large part of the range is supplied with the appropriate O-rings and corresponding accessories.

New water pumps for demand-based repairs

As a further addition to the thermal management program, Bosch is introducing the electric main water pump at the end of 2026. While the electric auxiliary water pump, established in the Bosch portfolio, supports the various coolant circuits in both combustion engine and electric vehicles, the main water pump is responsible for the fundamental and reliable cooling of the engine. Its operation, independent of the engine, enables optimized cooling performance, particularly in modern powertrains, including hybrid and electric vehicles. The range includes 12 part numbers for common passenger car models from BMW, Mercedes-Benz, and Toyota. All products meet original equipment quality standards, ensuring reliable function and a long service life.

To provide workshops with more flexibility in repairing belt-driven systems, the mechanical water pump will also be available as an individual part in the future – in addition to the well-known belt kit including a water pump. From the end of the third quarter of 2026, 70 part numbers for the timing drive will be available. In early 2027, around 120 more part numbers will follow, with approximately 40 for the timing drive and 80 for the accessory drive. With this, Bosch covers a large part of the European vehicle fleet.

A/C components program to be further expanded

The program of A/C components, first introduced in early 2024, is growing particularly strongly. From the beginning of 2027, around 500 new part numbers will expand the range,from compressors and condensers to dryers, evaporators, and expansion valves. This increasesthe European vehicle park coverage for condensers to over 90%. A highlight that underscores the expertise for modern drives is a new dryer for various Tesla models. For simple and professional installation, all A/C components are supplied with the matching O-rings. Strict endurance, leak, and corrosion tests ensure the reliable performance and long service life of the parts.

Continuous expansion of the existing range

The existing portfolio is also continuously adapting to the needs of workshops. In the cabin blower segment, Bosch is expanding the program at the end of 2026 with 20 new part numbers. The new blowers are available for passenger cars and light commercial vehicles from the brands VW, Renault, BMW, and Peugeot in the European market. In the engine cooling fan segment, the range will also expand from the beginning of 2027 by ten more part numbers for common models from VW, Renault, and Peugeot. The quality spare parts for the independent aftermarket are suitable for passenger cars and light commercial vehicles. Both product ranges will be consistently expanded to meet market requirements.

Comprehensive system expertise and a broad range from a single source

With the development and expansion of its thermal management business, Bosch ensures that workshops can rely on an even more comprehensive range of products from an experienced partner for service and repair cases. "Our claim is to stand by workshops as a strong and reliable partner. That is why we are consistently expanding our thermal management program. This is crucial, especially regarding electromobility, because intelligent thermal management is the key to the performance and service life of future vehicle generations. With our expanded portfolio, we are sharpening our expertise and supporting workshops with the requirements of future vehicle generations," says Carsten Kopp, member of the Bosch Mobility Aftermarket divisional board, responsible for development and product areas.

The entire range is available to workshops through the usual distribution channels. All newly added products are listed in both the Esitronic diagnostic software from Bosch and the TecDoc electronic parts catalog.
