Top 10 Automotive Aluminum Radiator Suppliers in China for B2B Buyers

China has many auto radiator factories, heat-exchanger companies, and export trading pages. This shortlist focuses on China-based suppliers with visible automotive cooling relevance, public scale signals, official websites, and practical value for B2B sourcing. It is a public research reference, not an official industry ranking.

• Best for supplier discovery: use the list to build an initial shortlist, not to make a final purchase decision.

• Best for procurement comparison: ask each supplier the same technical questions and compare the quality of their response.

• Best for custom projects: prepare drawings, samples, dimensions, core size, mounting details, application, quantity, packaging, and target market before requesting a quote.

Selection method

The selection method is simple: public official websites first, then product relevance, company scale signals, export visibility, and usefulness for overseas buyers. Large thermal-management groups and specialized radiator exporters are both included, because they solve different sourcing problems.

Search results for this topic often mix Chinese manufacturers, international brands with China operations, directories, and thin listicles. This article keeps the focus on suppliers that can be reasonably connected to China automotive radiators, aluminum radiators, cooling modules, condensers, intercoolers, or vehicle heat exchangers from public information.

Supplier shortlist

1. Zhejiang Yinlun Machinery Co., Ltd. (Yinlun)

Yinlun belongs near the top of any serious China thermal-management shortlist. Its official site presents it as a listed company focused on R&D, manufacturing, and sales of thermal-management and exhaust after-treatment products, with more than 40 holding subsidiaries. For buyers, the attraction is not a single radiator SKU; it is platform-level engineering depth for commercial vehicles, new-energy systems, and OE-style projects. The trade-off is that communication may be less direct for small aftermarket orders, so the first email should clearly state volume, drawing status, target application, and whether the project is OE, aftermarket, or special-vehicle development.

2. Nanning Baling Technology Co., Ltd.

Baling is a strong China-based heat-exchanger name with public scale signals. Its official site says the company was founded in 2001, has more than 40 years of production experience, covers 500+ products, and sells more than 3.6 million units annually. The product scope includes radiators, intercoolers, heaters, plate-fin heat exchangers, and cooling modules. It is worth watching for buyers who care about passenger-car supply experience and documented systems such as IATF 16949, ISO 14001, ISO 45001, and ISO/IEC 17025 laboratory accreditation. Because the site is mainly Chinese, overseas buyers should confirm export workflow and English engineering support early.

3. Guizhou Yonghong Radiator Co., Ltd.

Figure: Official homepage screenshot: Guizhou Yonghong Radiator Co., Ltd..

Yonghong is listed on the Guizhou Guihang Automotive Components website under thermal-management systems. Public pages identify Guizhou Yonghong Radiator Co., Ltd. and list products such as aluminum water radiators, composite aluminum water radiators, all-aluminum water radiators, oil coolers, intercoolers, and heater assemblies. This makes it relevant for buyers who want a supplier with automotive component background rather than only a trading storefront. The public information is not written mainly for export buyers, so verification should focus on current product drawings, project contact person, export references, and available certificates.

4. FARET Group / Guangdong Faret Auto Radiator Co., Ltd.

Figure: Official homepage screenshot: FARET Group / Guangdong Faret Auto Radiator Co., Ltd..

FARET presents itself more like an export-facing thermal-management brand. The English homepage says the group has focused on automotive thermal management for 26 years and serves more than 60 automotive brands worldwide. That positioning is useful for buyers comparing radiator, condenser, heater, and cooling-system suppliers with international presentation. The important detail is entity clarity: group pages can cover several locations or business units, so buyers should confirm which factory, legal company, and product line will handle the quotation.

5. Guangdong Xintongshi Group Co., Ltd. (Tongshi)

Figure: Official homepage screenshot: Guangdong Xintongshi Group Co., Ltd. (Tongshi).

Tongshi is a practical catalog-style radiator supplier to evaluate when the project involves passenger-car radiators, commercial-vehicle radiators, new-energy radiators, mechanical radiators, heaters, or generator radiator categories. Its English site highlights 20+ years focused on automobile radiator R&D. For aftermarket distributors, the immediate question is usually not whether a factory can make a radiator; it is whether the factory has the right OE numbers, model coverage, MOQ policy, packing options, and stable repeat-order control.

6. Guangzhou Kinga Autoparts Manufacture Co., Ltd.

Figure: Official homepage screenshot: Guangzhou Kinga Autoparts Manufacture Co., Ltd..

Kinga is easy to understand from a sourcing perspective: the website is built around aluminum car radiators and brand/model categories. That makes it useful for importers who are browsing Toyota, Nissan, Hyundai, Mitsubishi, Honda, Mazda, Suzuki, Mercedes-Benz, BMW, Ford, condenser, plastic tank, and radiator-related replacement lines. It looks more aftermarket-oriented than system-development oriented. Buyers should therefore ask for item-level drawings, OE cross references, leak-test method, material details, packaging photos, and sample lead time before making a broader purchasing decision.

7. Guangdong Hongdao Heat Exchange Technology Co., Ltd.

Figure: Official homepage screenshot: Guangdong Hongdao Heat Exchange Technology Co., Ltd..

Hongdao positions itself as a Guangzhou-based automotive cooling-system manufacturer. Its company page states more than 14,000 square meters of construction area and export coverage to more than 70 countries and regions. The website is especially visible for condensers, but it also presents radiator and cooling-system categories. This supplier may fit buyers who want a one-contact source for condensers, radiators, intercoolers, and heaters. For radiator projects, the RFQ should be precise about vehicle model, OE number, sample requirement, packaging, and market standard.

8. Guangzhou Dexin Radiator Co., Ltd.

Figure: Official homepage screenshot: Guangzhou Dexin Radiator Co., Ltd..

Dexin's homepage presents a focused automotive cooling product factory: radiators, condensers, auto heaters, intercoolers, and related parts. The public message is straightforward rather than corporate: R&D, design, production, sales, and after-sales service for automotive radiators. That is useful for buyers who prefer specialized suppliers with a narrower cooling-parts focus. Before ordering, confirm the exact part family, pressure-test standard, fin and tube structure, warranty terms, and whether private-label packing is available.

9. Zhejiang Zhuojin Locomotive Parts Co., Ltd.

Figure: Official homepage screenshot: Zhejiang Zhuojin Locomotive Parts Co., Ltd..

Zhuojin is another supplier with clear product breadth. Its official site says the factory produces automotive radiators, AC condensers, AC heaters, intercoolers, oil coolers, industrial radiators, aluminum heat exchangers, and related parts. It also highlights logistics access near Shanghai and Ningbo ports. For buyers, this can be convenient when consolidating several cooling-product categories. Site-stated patents or certifications should still be checked with current documents before using them in customer approval files.

10. Yangzhou Zuoer Radiator Co., Ltd. (ZUOER)

Figure: Official homepage screenshot: Yangzhou Zuoer Radiator Co., Ltd. (ZUOER).

Zuoer is included because it is directly relevant to aluminum radiator sourcing and because the user requested it. Its official site covers aluminum radiators, aluminum car radiators, aluminum truck radiators, generator radiators, intercoolers, oil coolers, condensers, radiator cores, and heat exchangers. The About page states that the company is located in Yangzhou Economic Development Zone and has annual production capacity of more than 300,000 radiator products. It is best positioned as a specialized supplier for buyers who need custom aluminum radiator communication, application matching, and practical RFQ support rather than a broad public-company platform.

How to compare the shortlist

A buyer should not judge a radiator supplier only by homepage design or catalog size. The better signal is how the supplier responds to technical uncertainty. A strong factory usually asks about core dimensions, inlet and outlet layout, pressure, mounting space, fan shroud clearance, vehicle or engine model, packaging, and test requirements before giving a final answer.

For existing aftermarket parts, ask for OE number matching, sample photos, carton details, MOQ, mixed-container policy, and warranty terms. For custom aluminum radiators, compare engineering questions, drawing feedback, sample schedule, pressure/leak testing, welding or brazing process, and packaging strength. Buyers evaluating Zuoer can also use its guide onwhat information buyers should provide before ordering a custom radiator as an RFQ checklist.

FAQ

Are these the only automotive aluminum radiator suppliers in China?

No. China has many radiator and heat-exchanger suppliers. This list is a public-source shortlist for B2B buyers, not a complete directory.

Should I choose a large group or a specialized radiator factory?

Choose by project type. Large groups may fit OE-style thermal-management projects. Specialized factories may be faster for aftermarket, mixed SKU, and custom aluminum radiator work.

What should I send for a radiator quotation?

Send drawings or photos, overall dimensions, core size, inlet and outlet layout, mounting details, application, engine or vehicle model, quantity, packaging needs, and target market.

How do I verify radiator quality before placing a bulk order?

Request sample approval, material details, pressure or leak test method, inspection records, packing photos, current certificates, warranty terms, and pre-shipment inspection options.

Why include Zuoer in this list?

Zuoer is directly relevant to aluminum radiator and custom cooling-product sourcing, and its website provides product, application, factory, and inquiry information for B2B buyers.

Final buying note

For a real sourcing project, shortlist three to five suppliers and send the same technical file to each. The most useful reply is rarely the cheapest one-line quotation; it is the answer that clarifies application, dimensions, testing, packaging, and production risks before price is finalized. Buyers comparing custom or application-specific aluminum radiators can review Zuoer's product pages and send project details for confirmation.
