The precautions for using ceramic cylinder liners are as follows:
1. During installation, the integrity of the inner coating should be ensured to avoid scratches and detachment. Due to its ability to expand and contract sensitively when heated, minimize contact with hard objects as much as possible;
2. It is recommended not to arbitrarily change non original waterway designs, including adding, removing, or modifying parts and devices such as drain switches;
3. Do not pour acidic substances into the engine cooling system to prevent corrosion of the gasket and water leakage;
4. As one of the components operating under high temperature and pressure, it has a strong magnetic field. Please do not place metal objects or small items that are prone to falling near this area, as it may cause damage and result in accidents with serious consequences;
5. Pay attention to the maintenance cycle and conduct regular inspections.    
In short, it is necessary to operate and use it reasonably according to the actual situation, and timely pay attention to relevant information for correct maintenance and processing in order to ensure and extend the service life to a certain extent!
