Diesel generator coolant replacement:
It should be replaced after 200 hours or three months after first use, and every 500 hours or one year thereafter. Carefully remove the top cover of the water tank and open it. the drain valve under the water tank, make sure the discharge port is not blocked, flush the cooling system with clean water after draining the cooling water, close the drain valve drain, fill the coolant, cover the top cover, pay attention to the appliance just stopped, do not open the water tank cover within 15 minutes to avoid water vapor bursts and could injure people.
In this case, the water level is not higher than the overflow pipe.
When checking the generator cooling water, it is necessary that the water level does notis not higher than the upper end of the inspection port. Indeed, when the generator is operating, the heat generated by the engine must be dissipated by the circulation of the cooling water. If the cooling water cannot circulate normally or the water level is too high, the cooling effect will decrease, thereby affecting the normal operation of the generator.
When the cooling water level is too high, water may escape from the cooling system and easily cause water accumulation inside the engine. At the same time, it is easy to cause moisture inside the machine, causing the insulation material of the generator to age and shorten its service life. Therefore, when checking the cooling water level, the water level should not exceed the upper end of the inspection port.
