Core Material: High-Strength Die-Cast Aluminum Housing

Category: Engine Cooling System

Compatible Vehicles

Core Engine: Custom-designed for the Yuchai 490 series diesel engine.

Compatible Trucks: Widely used in light and medium-duty trucks from JAC, Foton, and Dongfeng manufacturers.

Construction Machinery: Compatible with forklifts, mini excavators, and mobile generator sets equipped with this engine.

Matching Standard: Original factory-specified mounting holes, supporting non-destructive installation with the original vehicle's fan blades.

Product Features

Intelligent Temperature Control: Built-in high-sensitivity temperature sensor automatically adjusts fan speed according to engine temperature to ensure optimal operating temperature range.

Energy Saving and Noise Reduction: Automatically disengages at low temperatures to reduce engine load and fan noise; engages at full speed at high temperatures to improve heat dissipation efficiency.

Precision Manufacturing: Utilizing highly stable imported silicone oil and high-temperature resistant sealing rings, it completely eliminates oil leakage issues, ensuring smooth and vibration-free operation.

Optimized Lifespan: By reducing unnecessary fan operation, fuel consumption is lowered, while effectively extending the service life of the water pump and belts.

Harsh Operating Conditions: Its robust structure maintains sensitive response even in urban traffic jams with start-stop cycles or under heavy loads.
