Emergency-rescue service: In the event that the vehicle cannot move due to the malfunction of the expansion tank, Sinotruk can provide emergency rescue services, such as towing services by towing the vehicle to the nearest maintenance point for repair.

Below are methods for eliminating the common malfunctions of the expansion tanks of Sinotruk:

Cooling fluid leak

Check the water tank body: carefully examine the outer part of the expansion tank, including all parts of the tank body for cracks or damage. If small cracks are detected, they can be repaired using a special tool for repairing water tanks. In the presence of larger cracks or damage, as a rule, it is necessary to replace the expansion tank with a new one.

Check the joints of the water pipes: check the connections of water pipes connected to the expansion tank for weakening or poor sealing. If the connection is weakened, tighten it with a wrench. If the seal is not suitable, the sealing laying can be damaged and it must be replaced by a new one.

Check the welded joints: if the expansion tank is a welded structure, check if there are open welds in the welding sites. With minor ruptures of welded joints, welding equipment can be used for repair; If the gaps of welds are serious, a water tank may be replaced.

Anomalous water level

The water level is too high: first check if there are clogs in the cooling system, for example, in a radiator, a water pipe, etc. You can blow the radiator and water pipes with compressed air to remove pollution and dirt from them. If the water pump is out of order, which led to a deterioration in coolant circulation, it is necessary to check if the impeller of the water pump is worn out, whether the shaft is jammed, etc., and if necessary, replace the water pump.

The water level is too low: find the place of coolant leakage, inspect and eliminate it in accordance with the above methods for eliminating the malfunctions associated with the coolant leakage. If the cooling liquid is consumed too quickly due to the internal malfunction of the engine, for example, due to the damaged cylinder laying, the engine must be disassembled and the cylinder gasket is replaced. Check the cylinder sleeve and the cylinder head for the presence of sand shells or cracks, if necessary, repair or replace the corresponding parts.

Anomalous pressure

Too high pressure: check the cooling system for blockages, especially the radiator and water pipes. Clean the surface of the radiator from garbage and provide good ventilation between the ribs. If the radiator is clogged from the inside, you can use a professional cleaning tool to clean it. In serious cases, the radiator must be replaced. Check if the cooling fan works normally. The insufficient speed of rotation of the fan and the volume of air will affect the effect of heat dispersion, which will lead to too high the temperature of the coolant and increased pressure. If the fan is out of order, it is necessary to check the fan engine, the fan belt and other components and repair or replace them.

Too low pressure: check if the lid of the expansion tank is well sealed. Acting or damage to the sealing rubber ring of the lid can lead to pressure leakage. Replace the lid or sealing ring with new ones. Check if the pipes connecting the expansion tank with water and the cooling system are clogged. If there are blockages or bends, clean or adjust the pipes in time.

Water sensor malfunction

Check the sensor itself: Using the multimeter, measure the resistance or voltage of the water level sensor to make sure that it is within normal limits. If the sensor is damaged, it must be replaced with a new one.

Clean the sensor sensor: if the sensor sensor is covered with dirt, this will affect the determination of the water level. To clean the sensor, use the detergent and make sure that the surface of the sensor is clean.

Check the sensor circuit: check the reliability of the connection of the water level of the water level and the absence of cliffs or short circuits. If the line is faulty, it must be repaired or replaced.

When eliminating malfunctions, strictly follow the operating rules to ensure safety. If you are not sure how to eliminate certain malfunctions, it is recommended to seek help from professional technical personnel.
