Can We Add Water to the Water Tank of the Diesel Generator Set

Is it possible to add water to the water tank instead of coolant, as the temperature in the south is indeed high and not prone to freezing? However, Dingbo Power recommends adding coolant if conditions permit.

Requirements for adding water to diesel generator set coolant:

1. Do not add well water or sewage. Water can be divided into two types based on whether it dissolves minerals: hard water and soft water. Hard water contains iron, calcium, and magnesium plasma. Untreated well water and spring water belong to hard water. If such hard water is added to the diesel generating set, it will produce compounds such as calcium carbonate and calcium sulfate after being heated and evaporated by the engine, which will precipitate and form scale. And scale, on the one hand, is a poor conductor of heat, and on the other hand, when scale increases to a certain extent, it will narrow the pipeline, reduce the flow of water, and affect engine heat dissipation, causing engine overheating. The sewage contains sediment and decaying organic matter, which can easily corrode the water tank and cylinder jacket, affecting their service life.

2. Don't ignore asking. Do not run without water. When driving in hot weather, the evaporation of coolant in the water tank accelerates. It is important to always check the amount of coolant and observe the coolant temperature gauge. If the water tank is not fully filled, there is a problem with the coolant circulating inside the water jacket, and the water temperature can easily rise, causing boiling. Some models have difficulty filling up when adding water, and their water tank is located lower than the engine. When adding water, the water inlet of the water tank shows that it is already full, but in reality, there is a shortage of water in the engine water jacket.

3. When the water tank is boiling, do not open the lid hastily. Because the temperature inside the water tank is very high (at least 100 ℃) and the pressure is high when boiling, suddenly opening the water tank cover will cause the boiling water and steam to spray out rapidly, which can easily scald the water dispenser. When boiling occurs, it is generally recommended to idle and wait for the engine temperature to drop before opening the cover and adding coolant. If time is tight, cover the water tank cover with a damp cloth first, then wrap your hands with a damp towel, and then slowly open the water tank cover. In addition, the speed of adding coolant should not be too fast and should be slowly added.

4. Do not spill water onto the engine when adding water. When adding water, splashing it onto the spark plug socket, high-voltage wire socket, and distributor of the engine may have an impact on the ignition; Water splashing onto the drive belt may also cause it to slip; Spraying it onto the body may also cause deformation or even crack formation.
