Cooling System Controller Assembly OE 3613520-KZ901 for Dongfeng New Energy Truck Parts

This cooling system controller assembly OE 3613520-KZ901 is manufactured to exact Dongfeng New Energy original specifications, featuring a high-efficiency aluminum alloy casing that rapidly dissipates heat during continuous high-load operation. The product integrates a precision microcontroller unit (MCU) and multiple power drive modules, ensuring real-time monitoring and adjustment of the battery pack, motor and powertrain temperatures. Its heavy-duty high-current wiring harness with corrugated insulation provides excellent flexibility and resistance to abrasion, oil, and chemical exposure. The industrial-grade waterproof connectors feature a secure locking mechanism, preventing moisture and dust ingress in harsh operating environments. Its 1:1 original dimension design ensures perfect alignment with the truck’s chassis, allowing for a seamless, plug-and-play installation.

Electric truck operators often face critical issues with substandard cooling controllers, including inefficient thermal regulation leading to overheating, battery performance degradation, and even thermal runaway; faulty control circuits causing system shutdowns; and poor connector sealing resulting in short circuits and component damage. A faulty cooling controller can lead to vehicle breakdowns, reduced range, and safety hazards for fleet operations. By choosing the genuine OE 3613520-KZ901 controller, users can instantly resolve these problems, ensuring stable thermal management and protecting the vehicle’s high-voltage systems from damage.

As a core safety component for heavy-duty electric trucks, this cooling system controller complies with Q/DFL 6020-2021 Dongfeng original parts quality standards and has passed comprehensive third-party EV testing. Test data verifies it maintains stable thermal control accuracy within ±1°C after 10,000 hours of continuous operation, achieves an IP67 waterproof rating to prevent short circuits, and withstands extreme temperature fluctuations without component failure. Each unit undergoes 100% functional testing, vibration resistance testing and connector reliability verification before leaving the factory, guaranteeing complete consistency with the original factory controller in terms of performance, lifespan, and reliability. Backed by official factory traceability codes, this product ensures genuine quality and long-term trouble-free operation.
