This phenomenon occurs when the machine is suddenly damaged. Sudden damage to the machine will cause the coolant to stop the pressure circulation or a large number of water leakage and sudden overheating, or temperature test system failure.
The reason
Temperature sensor failure, false water temperature is too high.
Water table failure, false water temperature is too high.
The pump is suddenly damaged and the coolant stops circulating.
Baotou North heavy truck parts fan belt broken or belt pulley support loose.
Fan belt out or damaged.
The cooling system of serious Water Leakage.
The radiator is clogged with ice.
The diagnosis and treatment methods
First observe whether there is a large number of external engine leakage. Such as water switch, water pipes, water tanks and other places whether there is water leakage, if it should be timely treatment.
Observe whether the belt is broken. If the belt is broken, it should be replaced in time.
Check whether the water temperature sensor and water temperature gauge of Baotou North heavy truck parts are damaged.
Check whether the exhaust pipe of the engine and the water tank of the North Baotou heavy truck parts are blocked and clear.
If the engine of the Water Leakage, belt drive is normal, should check the coolant circulation pressure, check the repair according to “boil” fault.
The radiator freeze in cold season _ generally occurs after a cold start or downhill slide off. If the starting speed is high, and the lower part of the radiator fan strong ventilation, just add cold water ice, until the engine temperature rises, the cooling liquid of circulation and produce hot or boiling quickly. This should take precautionary measures to reduce the amount of ventilation radiator, fan, or freeze part of heating on the radiator, to quickly dissolve ice. When the car downhill radiator freezes, should immediately stop idling, warm car.
The matters needing attention
The choice of the wind or the shade immediately stop, open the engine hood, keep the engine idling, the temperature gradually decreased, banned immediately shut down.
If the engine is difficult to start after flameout, we should try to slow the crankshaft to prevent the piston and cylinder wall adhesion.
During the cooling process, it is not possible to open the radiator cover or the expansion box cover. When you open the lid, you should pay attention to safety, to prevent high temperature water or steam eject burns.
If the water consumption is too much, should be added in a timely manner appropriate soft water.
