According to the loader manufacturer, backhoe loaders are commonly used in earthmoving and construction projects related to hydropower, ports, highways, railways, buildings, and mines. They can be used to shovel and load loose materials such as soil, sand, gravel, lime, and coal, and can also perform excavation and other operations, with attachments installable on both ends.
However, this versatile equipment also has its "fatal flaw," and the water tank is a crucial component of the backhoe loader. What methods can be used to address water tank malfunctions?
Check the water level in the water tank. Turn off the engine and wait for the engine and water tank to cool down before performing any checks. Check the coolant level in the auxiliary tank. Normally, there is no need to open the radiator cap. If there is no auxiliary tank, the radiator cap must be removed, following the operating instructions.
Observe whether the water level has dropped. Only check the water level after it has dropped. Keep your hands away from the engine and water tank, and check the surrounding air temperature. Do not directly touch the engine or water tank. Loosen the radiator cap first to release all the pressure in the water, and then gradually remove the cap.
When the backhoe loader overheats, another situation can occur – "boiling over." The diesel engine temperature is too high, and the coolant boils and steams in the water tank. This indicates that the inner wall of the radiator tubes (core) has excessive scaling, affecting heat dissipation. When using the machine, ensure that clean coolant is added and that scale is regularly removed from the water tank; radiator or cooling system leaks can lead to insufficient coolant. Check the cause of the leak, repair the fault, and add sufficient coolant; a damaged cylinder head gasket or cylinder liner allows high-pressure gas from the cylinder to enter the water cooling system, causing the water tank to "bubble" and "boil over."
This situation is often accompanied by emulsified diesel engine oil. Check for damage to the cylinder head gasket or cylinder liner, and replace them if necessary.
