Indonesia, as the largest economy in Southeast Asia, has seen an unprecedented surge in its automotive and industrial sectors. From the bustling streets of Jakarta to the heavy mining terrains of Kalimantan, the demand for high-efficiency Automotive Oil Cooler Cores has never been higher. As a specialized supplier and exporter, we understand that Indonesia's tropical climate presents unique challenges for engine thermal management.
In urban centers like Jakarta and Surabaya, "Stop-and-Go" traffic is a daily reality. This condition places immense stress on automatic transmissions and engine lubrication systems. Our Aluminum Plate Fin Oil Cooler Cores are designed specifically to provide maximum heat dissipation even at low airflow, ensuring that passenger cars and commercial delivery vans maintain optimal operating temperatures, preventing premature oil degradation and transmission failure.
Furthermore, the industrial landscape in Indonesia is heavily reliant on heavy-duty machinery. Our oil cooler cores are widely integrated into construction equipment used in national strategic projects (PSN), including toll road expansions and new capital city (IKN) developments. Whether it's for a Cummins-powered excavator or a Hino truck, our cores are built to withstand the humid and dusty environments typical of Indonesian worksites.
Established in 2007, Zhejiang Rock Auto Co., Ltd. has been a leading manufacturer, exporter, and supplier of high-performance auto cooling system components. We specialize in producing a wide range of automotive cooling solutions, including radiator tubes, intercooler tubes, oil cooler tubes, as well as radiators, intercoolers, and oil coolers.
With more than 15 years of industry experience, Zhejiang Rock Auto has earned a reputation as a pioneer in the design and manufacturing of aluminum-based cooling products. We are committed to providing high-quality, cost-effective, and innovative solutions that meet the rigorous demands of our global customers in Indonesia and beyond.

The Indonesian market is currently witnessing a significant shift toward High-Performance Lightweight Materials. Traditional heavy copper coolers are being replaced by Brazed Aluminum Plate-Fin technology. This trend is driven by the Indonesian government’s focus on fuel efficiency and emission reduction (Euro 4 and Euro 5 standards implementation).
With the rise of nickel processing and EV battery manufacturing in Indonesia (Morowali and Weda Bay), there is a growing need for specialized battery cooling plates and motor oil coolers. Our R&D department is already testing cores that cater to these new energy vehicles.
Indonesia's "Global Maritime Fulcrum" vision requires robust cooling for marine engines. Our brass-core and aluminum radiators are increasingly used in inter-island logistics vessels that operate in salty, corrosive environments.
In the coal mines of East Kalimantan, equipment uptime is critical. Our oil cooler cores for Cummins and Komatsu engines are reinforced to handle high-vibration and extreme pressure fluctuations.
Our R&D unit is the cornerstone of our business, conducting detailed research and surveys to improve the performance and durability of our products. This commitment to innovation allows us to design new products with superior functionality, tailored to the specific needs of our clients in the Indonesian automotive aftermarket.
We are proud to be ISO/TS 16949 certified, and our state-of-the-art manufacturing facility is equipped with advanced technologies, including Brazing Furnaces, Fin Machines, and Core Assembly Machines.
To deliver high-quality and cost-effective cooling solutions that not only meet but exceed customer expectations, while fostering a culture of innovation and sustainability.
To be a global leader in the auto parts industry, recognized for our advanced technologies, outstanding customer service, and environmental stewardship.
Whether you are a wholesaler in Bandung, a fleet manager in Medan, or a mining contractor in Balikpapan, Zhejiang Rock Auto Co., Ltd. is your reliable partner for premium cooling solutions.
