Check the relay of the fan for damage.
Check whether the fuse is broken.
If all the above are all right, you'd better go to the garage to have a check.
Automobile water tank is an important part of water-cooled engine and the cooling circuit of water-cooled engine. Water is used as the heat carrier to conduct heat, and then heat is dissipated by convection through large-area fins to maintain the appropriate working temperature of the engine.
Precautions for use:
The radiator should not be in contact with any acid, alkali or other corrosive substances.
It is recommended to use soft water, and soften hard water before use to avoid internal blockage and scaling of radiator.
When using antifreeze, in order to avoid radiator corrosion, please be sure to use long-term antirust antifreeze produced by regular manufacturers and in line with national standards.
In the process of installing the radiator, please don't damage the heat dissipation belt (sheet) and bump the radiator to ensure the heat dissipation ability and sealing.
When the radiator is completely drained before adding water, turn on the drain switch of the engine cylinder first, and then turn it off when there is water flowing out to avoid blisters.
Check the water level at any time in daily use, and add water after stopping the machine to cool down. When adding water, slowly open the water tank cover, and the operator's body should be as far away from the water inlet as possible to prevent high-pressure steam from spraying from the water inlet and causing burns.
In winter, in order to prevent the iron core from cracking due to icing, such as long-term parking or indirect parking, the water tank cover and drain switch should be used to drain all the water.
The effective environment of standby radiator should be kept ventilated and dry.
