1. Check the heat pipe radiator. Mini excavators work in harsh environments all year round, so there is always a lot of dust and small debris blocking the hydraulic machine heat pipe radiator and water tank heat pipe radiator, especially when the hydraulic machine pipe radiator is exposed for a long time. As long as the heat pipe radiator is blocked behind the water storage tank, attention should be paid to the exposure of the hydraulic machine heat pipe radiator.
2. Check the cylinder head gasket of the small excavator. What kind of water is in the water tank during the circulation process. It could be a bubble. If that's the case, what's wrong with the cylinder head of the engine?
3. Check the pump operating equipment, and then squeeze the pipe by hand. If the extrusion feels strong, this means there is nothing wrong with the pump. If it is easy to extrude, the circulation system of the pump is not very good.
4. Check whether the water tank cover is damaged, which will also cause the temperature to rise. Because the tank is united, it is easy for water to enter the water circulation system, so the temperature will be higher.
5. Check whether the thermostat can be opened or is stuck.
6. Check that the fan speed is faster and cannot keep up with the motorized pulley. This is also why the temperature rises very easily.
