What is a fan belt?

Release time：2022-05-04    Click：95

Fan belt is an important automotive component mainly used to connect the crankshaft with fan pulleys, 

water pump fan pulleys, and charger fan pulleys. It drives the water pump, fan blades, and charger in the 

cooling system through the power of the crankshaft.

Daily inspection and maintenance

Inspection frequency: It is generally recommended to regularly check the wear of the fan belt after driving 

80000 kilometers.

Inspection content: Observe whether the belt has any damage, peeling, cracking, wear, or abnormal cracks. 

At the same time, pay attention to whether the tension of the belt is appropriate, as being too loose or too

 tight can lead to problem 1.

Timing of replacement: When severe belt wear, numerous cracks, or abnormal rubber surface wear is found, 

it should be replaced in a timely manner.

Replacement and maintenance

Replacement cycle: Although there is no fixed replacement cycle, it is generally recommended to inspect 

the vehicle after 80000 kilometers of driving, and replace it if necessary.

Maintenance method: Keep the fan belt clean, avoid contact with corrosive substances such as oil stains, 

regularly check and adjust the tension of the belt appropriately.

precautions

Avoid sudden breakage: Fan belts usually do not break suddenly, but gradually loosen due to long-term 

lack of adjustment, ultimately leading to wear and detachment.

Impact: If the fan belt breaks, it will cause the cooling system to fail, the engine to overheat, and the 

charger to not work properly, which may result in the vehicle being unable to start.

In summary, the fan belt is an important part that cannot be ignored in vehicle maintenance, and regular

 inspection and timely replacement are crucial to ensure the normal operation of the vehicle.
