A20F2-1308150A DONGFENG TRUCK YUCHAI ENGINE FAN ASSEMBLY

The Yuchai A20F2-1308150A Engine Cooling Fan Blade is an original equipment (OE) radiator fan manufactured by Guangxi Yuchai Machinery Co., Ltd. (Yuchai Power) for heavy-duty diesel engines. Designed as a critical component of the engine cooling system, this 9-blade circular fan with integrated outer ring (ring-type design) delivers high-volume airflow to maintain optimal engine temperature — especially during low-speed operation, idling, or heavy-load conditions such as climbing or hauling.

Engineered for use on Yuchai YC6A and YC6J series engines, it is widely installed on commercial trucks from Dongfeng, SHACMAN (Xuande), and major bus manufacturers like Yutong and Zhongtong. Constructed from high-strength glass-fiber reinforced nylon (PA66+GF), the fan offers excellent heat resistance, structural stability at high RPM, and reduced rotational inertia — protecting water pump bearings and fan clutch systems.
