Matters needing attention in the use of automobile water tank:
1, use soft water, hard water needs to be softened after use to avoid internal blockage and scale formation of radiator. When using antifreeze, in order to prevent the radiator from being corroded, please be sure to use the long-term antifreeze antirust liquid produced by regular manufacturers that meets the national standards.
2, in daily use, should always check the water level, water cooling after downtime. When adding water, the water tank cover should be opened slowly, 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.
