The engine is like the heart of the car，The importance is self-evident。Construction vehicles mainly used in construction，I usually work hard and the working environment is poor，What to do if the engine overheats?

There are generally two types of reasons that cause the water temperature of diesel engines to be too high: first，The cooling system is not efficient;Second，The engine itself failed。So how to determine what went wrong?Card friends can start checking from the following points。

Causes of excessively high operating temperature of diesel engines，The most common problem is insufficient coolant。Diesel seabet loginengine at work，Produces a lot of underutilized heat，Gathered on the engine parts。If coolant is low，Even if everything else is normal，The heat dissipation effect is not enough

Check thermostat

Generally，When the thermostat valve is at 78-88 degrees Celsius，As the temperature of the diesel engine gradually increases, it gradually turns on，Coolant is increasingly participating in the engine's large circulation cooling。The main reason for thermostat failure is that the main valve cannot be fully opened or is stuck between large and small cycles、Aging、Poor sealing causes leakage of the expansion body, etc.，These failures will lead to poor cooling water circulation and engine overheating。

Check engine oil level

Because the temperature of the diesel engine is relatively high，The requirements for the heat dissipation performance and lubrication performance of engine oil are also higher。In case of excessive oil addition，It will cause the engine to encounter greater resistance when working。And if the engine oil is insufficient，affects lubrication and heat dissipation，So when changing the oil，Must follow the requirements，More is not always better。

Check the fan

Now commonly used in heavy trucksSilicon oil clutchFan，Will adjust the speed through temperature changes，The key control component is the spiral on the front cover of the silicone fanBimetalThermosensor，If it breaks or fatigue fails，will directly cause the cooling fan to stop or run at low speed，Affects engine heat dissipation。Similarly，For other cooling seabet loginfans using belt links，You should check and adjust the tightness of the belt，Guarantee the fan speed。

Check the oil filter

Due to the working process of the diesel engine，It is inevitable that some metal wear debris will be produced，In addition, the entry of debris in the air、Generation of oil oxides，The impurities in the engine oil gradually increase。Many people want to save dozens of dollars，Using inferior machine filter，Not only easy to get clogged，Lost the role of intercepting impurities in engine oil，It will also increase the wear of other parts such as the cylinder block，The result is not worth the loss

Check own workload

▲Emergency treatment methods after the engine is overheated

This point，Needless to say, everyone understands。The engine is working under heavy load，Produces more heat，Especially when a heavily loaded dump truck is climbing a slope，It is very easy for the water temperature to be too high。If this happens often，Card friends should pay attention，The engine has been in this working condition for a long time，The service life will be greatly reduced，So it must be done in moderation、Act within your capabilities!

Actually，Engine "fever" is often caused by many reasons，Many of these low-level problems can be avoided through daily inspection，Car maintenance is definitely not a trivial matter。(The content of the article comes from the Internet，If copyright is involved, please contact us to delete。）
