The temperature of the water tank reaches the boiling point, that is, we as the saying goes " open the pot ", will cause the engine cooling bad, the temperature is too high.  The direct cause of the expansion of the internal parts of the engine to reduce the gap between the components, on the other hand, the temperature is too high oil viscosity reduction, in this case, the wear of the parts is aggravated.  If not properly dealt with immediately, the engine may be burnt to the loss causing serious damage to the machine.  

 If you want to suit the right medicine, the reason is the key.  The coolant in the tank is mainly used for heat dissipation of the engine. the following reasons will cause the coolant temperature of the engine water tank to rise:

 1. the thermostat card in the northern part of Baotou is dead and cannot be opened, when the water can only go through the small circulation, not through the radiator.  

 2. the water tank is not cleaned for a long time, causing the coolant circulation not smooth, which can be used to detect the temperature of the tank up and down, and the lower temperature will be very low.  

 3. not enough fan speed, clutch fault.  

 4. for the fifth point, it is easy to ignore that there will be no false alarm, the sensor is broken, and this is possible., the computer is very wooden, only the data do not look at the facts.  

 Many drivers find that the temperature of the truck's coolant is rising, and it is impossible to discern the reason, most of which will turn to the water to cool the water, some even rely entirely on it.  But in fact, if we can not find the real incentive, this kind of palliative treatment, the damage to the engine can not stop.  

 The temperature is too high for the first oil, then the water

 The cooling liquid in the water tank of the benchi fittings in the north of Baotou is mainly for the engine cooling service. when the coolant temperature is high, the oil temperature will increase, which will affect the normal work of the engine.  According to an expert with many years of experience, when encountering the high temperature of the engine oil temperature and water temperature, if the quantity of oil or water is insufficient or insufficient, the oil temperature should be reduced first and then the water temperature.  

 1. the high oil temperature is harmful to the engine

 The so-called engine temperature is too high, refers to the engine oil temperature, water temperature more than 90 degrees celsius.  When the two temperature is too high, it will affect the normal work of the engine, and bring some harm to the engine: the gap is reduced, forming serious wear or " scratch ".  

 According to the test, when the oil temperature reaches 110 ℃, the oil film temperature in the bearing clearance can reach 150 ℃.  If the oil film temperature is above 150 degrees celsius, it is easy to fracture and form half dry friction.  Because the crankshaft bearing is a copper lead alloy, if the reduction measures are not appropriate, the bearing temperature will be too high and lead to the melting of lead, the consequences will be disastrous.  Therefore, when the temperature of oil and water is too high, the oil temperature should be reduced first.  

 2. the oil temperature can slow the rising speed of water temperature

 The oil temperature drop usually adopts the method of " reducing load, low speed ".  At this time, although the cooling liquid at the high temperature parts of the heat exchange for a long time, but the flow speed slowed, extended the heat dissipation time.  At the same time, due to the decrease of load and speed, the heat of friction of each moving parts is reduced accordingly.  Therefore, the oil temperature can not only reduce the heat generated by the engine, but also indirectly reduce the amount of heat absorbed by the coolant, so as to slow the rise of water temperature.  

 3. the oil temperature is one of the main factors affecting the oil pressure

 When the oil temperature of the engine is too high, not only increase the fuel consumption ( leakage, evaporation, combustion ), but also affect the oil quality, so that the oil film of the friction surface of the engine parts is not easy to form and maintain, resulting in the oil pressure of the main oil road can not be established, thus aggravating the mechanical wear.  The effect of water temperature on oil pressure must be realized through oil temperature.  Therefore, with certain indirection, it takes a certain amount of time.  

 Therefore, based on the above three considerations, when the engine water temperature and oil temperature are too high, should first reduce the oil temperature to reduce the damage caused by the engine.  And while lowering the oil temperature, it will also reduce the temperature of the coolant.  

 Clean up the dirt on the tank in time

 When the coolant is missing, many drivers choose to fill it with water for the emergency, which is a very wrong approach.  Especially in summer, because the chlorine content in the tap water will corrode, rust, obstruct the water tank, engine and other systems, cooling the cooling system, reducing the cooling effect, resulting in the engine overheating, and even the engine damage.  Antifreeze oxidation will also form acidic material, corrosion of the metal parts of the water tank, causing damage to the tank, leakage.  

 The solution to the water tank failure is mainly on normal routine inspection, should often check whether the water tank leaks or rust, to clean on time, replace or add antifreeze, to improve boiling point, extend the service life.  In general, the antifreeze solution should be replaced for 20,000 kilometres or a year.  

 This can increase the boiling point, prevent the generation of scale, rust and enhance the heat dissipation effect, so that the pump produces lubrication, to avoid and eliminate the sudden high temperature caused by the bubble caused by the engine damage.  

 Here are to remind you that when the car is driving, the engine cover suddenly appears white steam, or the temperature of the water temperature indicator quickly rising to the high temperature " h" mark position, that is, the engine temperature is too high.  Usually due to the insufficient water quantity of the water tank, leakage or the fan not running of the water tank, it shall be handled in a timely manner.  

 Step 1: first of all, find a safe place to park, but don't stop immediately.  Keep the engine idling and continue to heat, while opening the hood to improve the heat dissipation.  

 Note: in the case of high water temperature and even open water:

 1. do not try to continue driving, in order to avoid causing serious damage to the machine.  

 2. do not try to open the lid of the tank, otherwise it is likely that there will be scalding hot liquid to cause burns.  

 3. don't pour cold water on the engine block and cylinder head, it is likely to cause the cylinder block to crack due to a cold snap.  

 Step 2: after a period of time, check the underside of the car for water leakage.  

 Step 3: wait until the thermometer pointer drops to the appropriate temperature position, turn off the engine.  

 Step 4: cover the water tank cover with wet towel, open the first switch slowly ( approx. 1 / 4 turn ), after the steam pressure is released, open the water tank cover completely, and check the water quantity and water quality in the tank, and whether the fan belt is abnormal.  If the water is insufficient, then slowly add water to the vicinity of the highest line.  

 Note: if the water tank leaks or fan belt loose, broken condition, you can call the traction company to wait for the trailer rescue.  If necessary, can also wait for the engine to completely cool down, in a low-speed way to drive the car to the service plant maintenance.  Remember that you cannot drive at normal speed, otherwise it is likely to cause permanent damage to the engine.  

 ● afterword:

 In the summer, the temperature rises gradually, should do the protective measures in time, prevent the water temperature and oil temperature too high, cause unnecessary harm to the benchi parts engine of Baotou north.  If encounter similar situation, also want to avoid the disease urgent to seek medical treatment, find the true reason of the increase of the coolant, solve the problem fundamentally, in order to ensure the safety of driving more properly.
