This is because the temperature of the water tank is too high and the pan is boiling. The reasons are:
1. The water temperature may be too high due to part failure.
(1) If you have an air conditioner If the idle speed is too low, the water temperature can be high. You need to check whether the air conditioner idle lever is working normally;
(2) The cylinder head is uneven or the cylinder gasket is flushed, which may result in high water temperature. When the engine is cold, open the water filler cap and start the engine. If bubbles come out of the water tank, this may be the problem.
(3) Failure of parts in the engine cooling system can cause the water temperature to be too high. The corresponding parts must be checked and replaced.
2. The water temperature is too high due to probleminstallation instructions.
(1) The distance between the water tank and the motor is too large and the fan is outside the wind circle. This can be solved by adjusting the installation position of the water tank.
(2) The air conditioning condenser is blocked in front of the water tank. There are two solutions: First, if there is enough space in the engine compartment, change the installation position of the air conditioning condenser. If the generator produces enough power, install an electric fan in front of the condenser.
3. The water temperature is too high due to usage and maintenance issues.
(1) The engine structure is compact and the corresponding water channel is small. In the southern region, soft water or distilled water should be added to prevent scale formation in the water channel. real coolant (antifreeze) to prevent cylinder head corrosion.
(2) When the engine is drained of water or too short of water, the air in the engine may not be completely exhausted after the first filling of water. If no action is taken, it could cause air blockage and engine malfunction. The temperature is too high. The solution is: after adding water, run the engine for a few minutes, open the water fill cap and fill it with water again.
(3) If the gasoline does not meet the standard or the ignition time is advanced, it may cause engine knocking and make the water temperature too high. The solution is: adjust the distributor and delay the ignition time. appropriately.
(4) The fan belt is too loose, which may cause the water temperature to be too high. The belt tension can be adjusted appropriately.
(5) Check engine oil and water beforeLeave and make sure the water tank is full.

The functions of the generator water tank anti-overflow pipe are as follows:
>1. -The overflow pipe is located on the side of the water tank and guides the water when adding water. And drain the coolant that overflows from the water tank to avoid staining and corroding the radiator hose and engine parts.
2. When the high pressure valve of the water tank cover is opened, guide the water vapor and high temperature liquid into the small water tank (expansion tank).
3. When the temperature drops, the water from the small water tank returns to the water tank through the pipe.
