The workload of the loader should be reasonably arranged to prevent the machine from overheating.6. The thermostat is damaged, causing the large cycle to fail to open, causing the machine to overheat, and the thermostat should be replaced. It should be noted that loaders working in high-cold areas will also experience a boiling phenomenon, the main reason is that the radiator is frozen and the coolant cannot be circulated. Therefore, when using loaders in high-cold areas, attention should be paid to adding heat preservation devices at the front of the radiator.
