The steps for adding water to the semi-trailer water tank are as follows:
Ensure the vehicle is turned off and cooled: Before adding water, make sure the semi-trailer is turned off and the engine has cooled down for a period of time to avoid burns from high-temperature steam.
Find the location of the water tank: The water tank of a semi-trailer is usually located at the front of the engine compartment, with a clear identification such as a thermometer icon or the words "coolant" or "water".
Open the water tank cover: Slowly rotate the water tank cover to release the pressure inside the water tank and avoid splashing hot water.
Prepare water source: Use clean soft water, such as distilled water or treated tap water, to reduce the formation of scale.
Add water: Slowly pour water into the water tank, being careful not to exceed the upper and lower limits of the tank scale.

Check sealing: After adding water, check whether the connection between the water tank cover and the water pipe is well sealed and whether there is any leakage.
Start engine inspection: Start the engine and check if the cooling system is functioning properly to ensure there are no leaks.
Attention:
Water temperature: When adding water, the water temperature should not be too low or too high. Too cold water May cause the water tank to rupture, while too hot water May cause burns.
Water quality: Avoid using water containing excessive impurities or minerals to prevent the formation of scale in the water tank, which can affect the heat dissipation effect. It is better to use specialized coolant instead of tap water.
Seasonal factors: In the cold winter, it is necessary to choose the appropriate antifreeze according to the local temperature to prevent the water tank from freezing.
Regular inspection: Regularly check the water level and quality of the water tank to ensure the normal operation of the cooling system.
