Heater Core Assembly with Sponge OE P10D760100 for Dongfeng GX&KX | Genuine Truck Part

This heater core assembly OE P10D760100 is manufactured strictly to Dongfeng GX&KX original design specifications, adopting a dense aluminum fin and tube structure that maximizes heat transfer surface area, delivering ≥92% heat exchange efficiency for rapid cabin heating. The product features pre-installed EPDM sealing sponge along all edges, which perfectly fills gaps between the core and HVAC housing, eliminating air leakage and ensuring maximum heat transfer to the cabin. The high-purity aluminum material offers excellent corrosion resistance and thermal conductivity, preventing scale buildup and maintaining long-term heating performance. It adopts a 1:1 original mounting design, with precisely sized coolant ports and mounting brackets that perfectly match the truck’s HVAC system, ensuring a tight, leak-proof fit. This integrated design combines efficient heating and sealing, making it the ideal OEM replacement for Dongfeng GX&KX heavy-duty trucks.

Fully compatible with all applicable Dongfeng GX&KX truck models, this heater core assembly can be quickly verified via OE P10D760100 to ensure accurate matching. It solves multiple common failures caused by low-quality aftermarket cores, including thin aluminum fins leading to poor heat transfer, missing sealing sponge causing air gaps and reduced heating efficiency, weak tube joints leading to coolant leakage, and mismatched ports causing installation difficulty. A faulty heater core will result in slow or no cabin heating, coolant loss and even engine overheating, creating an uncomfortable and unsafe driving environment in cold weather. By using this genuine core with sponge seal, users can eliminate poor heating, coolant leakage and air gap problems, ensuring reliable and efficient cabin heating.

As a key component for heavy-duty truck HVAC systems, this heater core assembly meets Q/DFL 6020-2021 Dongfeng automotive parts quality standards and has passed authoritative third-party tests for heat transfer efficiency, pressure resistance and corrosion resistance. Test data shows the core withstands 2.0MPa burst pressure without leakage, maintains stable heat transfer efficiency after 10,000 hours of operation, and remains corrosion-free after 500 hours of salt spray testing. Each core undergoes 100% full pressure testing, heat transfer performance verification and sponge seal fit inspection before leaving the factory, ensuring complete consistency with original factory parts in performance, durability and fit. It performs reliably in extreme cold and hot environments, with strong resistance to corrosion, pressure and wear. Backed by complete factory traceability and quality certification, it provides users with long-term, trustworthy cabin heating performance.
