• Stable cooling effect, keep engine temperature within normal range, reduce overheating and related engine faults.

FAQ 

Q1：What signs indicate the fan assembly needs replacement?
A1：Fan blade cracks, blade missing, hub deformation, obvious shaking and abnormal noise during rotation. Damaged fan leads to insufficient air volume and engine overheating.

Q2：What should be noted during fan assembly installation?
A2：Check whether the fan clutch is in good condition. Clean the contact surface of hub. Tighten bolts evenly in diagonal order. After installation, test rotation and check for swing.

Q3：What are the common causes of fan damage?
A3：Stone impact breaking blades; long-term high-speed rotation fatigue; unbalanced rotation causing crack; aging and embrittlement of material under high temperature.

Q4：Can single cracked fan blade be repaired?
A4：Not recommended. If one blade is damaged, the dynamic balance of the whole fan will be destroyed. Even simple repair, high-speed rotation will cause severe vibration, which may damage clutch and radiator, better replace whole fan assembly.

Q5：How to inspect fan assembly in daily maintenance?
A5：Check fan blades for cracks and missing pieces, listen for abnormal noise when engine runs. Clean dust and debris between fan and radiator regularly.

Q6：What risk will damaged fan bring?
A6：The air volume drops sharply, engine temperature rises quickly and overheats. Severe overheating can lead to cylinder pulling, which causes permanent damage to the engine.
