The engine is like the heart of the car，The importance is self -evident。Mainly operating engineering cars operated by construction workers，Usually the poor operating environment is poor，What happens when the engine is overheated?

There are two types of reasons for the high water temperature of diesel engines: first，The heat dissipation system is not powerful; second，The engine itself is faulty。So how can I judge where is the problem? Card friends can start from the following points。

Seabet

Causes of excessive working temperature caused by diesel engine，The most vulnerable thing is insufficient coolant。Diesel engine when working，It will generate a large seabet myamount of heat that has not been fully used，Gathering on the engine parts。If the coolant is insufficient，Even if everything else is normal，The cooling effect is not enough

Check the thermostat

Under normal circumstances，Temperature-saving valve is at 78-88 degrees Celsius，As the temperature of the diesel engine gradually increases, it gradually turns on，Cooling liquid is more and more involved in the engine large circulation cooling。The temperature -saving fault mainly has the main valve that cannot be opened or stuck between the size of the size、Aging、Poor sealing makes the expansion body leak, etc.，These faults will cause the cooling water cycle and the engine will be overheated。

Check the amount of oil and oil

Because the temperature is higher when the diesel engine works，The requirements for the heat dissipation performance and lubrication performance of the oil are also higher。Once you add motor oil，It will make the engine encounter greater resistance at work。If the oil is less，It also affects lubrication and heat dissipation，So when changing the oil，It must be according to the requirements，Not more, the better。

Check the fan

The silicone clutch fan is generally adopted by heavy cards now，It will adjust the speed through changes in temperature，The key control component is the spiral dual metal chip temperature sensor on the front cover of the silicon oil fan，If it breaks or fatigue，It will directly lead to the stopping or low -speed operation of the heat Seabetdissipation fan，Affect the engine heat dissipation。Similarly，For other cooling fans using belt links，Then check the tightness of the belt，Make sure the speed of the fan。

Check the oil filter element

During the work of diesel engine，It will inevitably produce a little metal abrasive，Add the entry of debris in the air、The production of oil oxides，Gradually increase the debris in the oil。Many people have to save dozens of dollars，Using inferior machine filter，Not only is it easy to block，Lost the effect of impurities in the interceptor oil，It will also exacerbate the wear of other parts such as cylinders，The result will not lose

Check your own work load

▲ Emergency treatment method after high temperature after the engine

This point，Needless to say everyone knows。The engine works under heavy load，It will generate more calories，Especially when the heavy -diverter truck is climbing，Very easy water temperature。If often this，Card friends must pay attention，The engine has been in such a working state for a long time，The service life will be greatly attenuated，So be sure to stop、Oh!

Actually，The engine "fever" is often caused by multiple reasons，Many of the low -level problems can be avoided through daily inspections，The maintenance of car love is definitely not a trivial matter。
