Under normal working conditions. Pump inlet pressure is lower than other parts of the pressure. The boiling point of water decreases with the decrease of pressure. Therefore, when the water temperature is too high, the boiling water may produce a lot of steam, the water pump water pump and water pump decreased sharply decreased, the cyclic strength of the cooling system is weakened, cooling performance is reduced, the water temperature increased, the water consumption increases, resulting in the amount of coolant is more insufficient, the water pump is lowered the whole system caused by the vicious spiral. The engine temperature increases sharply, if not immediately ruled out, not only to reduce the engine performance, and even accident damage.
The reason
Baotou North Benz parts pump leakage
The cylinder block or cylinder head is corroded seriously and leaking
Baotou North Benz parts radiator, water pipes, cylinder head, cylinder rupture.
Water tank cover is damaged or not sealed.
The diagnosis and treatment methods
First, check the north of Baotou BENZ Engine Parts and cooling system with no external leakage, such as pumps, radiators, water inlet and outlet joints. Secondly, to observe whether the water leakage pump leakage, if there is a drop of water or linear water outflow, indicating that the water pump has been damaged. When the cooling system is found to be leaking.
Check the cooling capacity is not enough. If the evaporation caused by the lack of cooling fluid should be added in a timely manner; if other reasons caused by insufficient amount of liquid, should find out where the leak, repair and then fill the coolant.
If the cooling system does not leak outside, and the coolant consumption is too fast, the engine must be checked for leaks. The method is as follows:
A) oil dipstick found oil emulsion, should check whether there are cracks cylinder.
(b) observe whether or not the oil inlet or crankcase vent at the white mist.
C) in the exhaust pipe by hand to see if there is no water on the hands and exhaust steam. And smell the smell of the hand, to determine whether the water or oil.
Through the inspection of the two can determine the cylinder into the water. If there is water in the cylinder, the cylinder liner is usually broken, the cylinder head is broken, the cylinder head is warped and the copper sleeve of the injector is not sealed.
