Usually, it is necessary to replace the antifreeze in time when driving a semi-trailer for one year or driving 20,000 kilometers. Do not add tap water if there is no antifreeze, because the water contains a lot of impurities, which will cause the tank of the transport semi-trailer to rust or produce dirt.
Take care to prevent the occurrence of faults when transporting the water tank of the semi-trailer. This is mainly from the daily inspection of the transport semi-trailer. During the inspection, pay attention to whether the water tank of the semi-trailer is leaking or rusting. Also pay attention to the regular replacement of the antifreeze, and increase the boiling point in the tank to prevent dirt. And improve the heat dissipation effect, etc., in order to better extend the life of the water tank.
