Summer，Hot waves not only make people feel uncomfortable，Even the car will launch a "high fever"。The following is some common reasons and solutions that are likely to cause high temperatures in the northern auto repair.，I hope to help you。

The surface of the radiator is blocked

Therapy: In fact, most of the high temperature problems of the engine are caused by the blocking of the radiator，To avoid this situation causes the engine high temperature，It is recommended that you will be in the past of the willows and willow wool every year，Captive cleaning seabet loginthe radiator，This can ensure that the entire summer heat sink can work in a good state。

Cover inside the radiator

Therapy: In fact, the current truck has rarely used water to make coolant，So the blocking land in the radiator has rarely appeared。If the truck uses water for a long time as a coolant，and high -temperature phenomenon，After checking elsewhere, there is no problem，Then check the internal heat sink，If the scale is blocked a lot，You can go to the repair plant that specializes in the radiator to clean up and clear。

Fan clutch failure

Therapy: The high temperature caused by the clutch fan failure is not a minority，It is difficult to judge whether it is normal，So you can only rely on replacement to verify whether the fan clutch has been damaged，If your car has a high temperature phenomenon，and there are no problems in other parts，May wish to consider replacing a fan clutch and try。

ignition the timing error

Therapy: In fact, after entering the era of electronic control，Basically, there is no high temperature caused by the engine caused by the timing error of ignition，But on some old engines using mechanical pumps，The high temperature caused by timing errors still occur from time to time。If the truck uses a mechanical pump，and high temperature phenomenon，Then I suggest check whether the ignition is within the normal range。

exhaust back pressure high

Therapy: Many people may not know，High back pressure of the engine can also cause seabet loginhigh temperature phenomena。Generally, there are two reasons that cause high exhaust and back pressure: First, the exhaust brake butterfly valve is poorly returned，Deliven poor exhaust。Second, blocking the muffler or SCR catalyst，As a result, the exhaust back pressure is too high，Both points may cause the engine temperature to be too high，and also reduce power to increase fuel consumption。

The temperature -saving device fails

Therapy: If you encounter high temperature phenomenon in the engine during driving，Be sure to check whether the working status of the thermostat is normal，But do not remove the thermostat without using it，Because it may cause the engine temperature to get out of control after removal，resulting in high fuel consumption、A wear exacerbated。

The above is some common reasons for the high temperature of the engine，Except for the reasons of the car itself，Improper operation can also cause the engine high temperature。So when you encounter such problems，Card friends must conduct a systematic inspection，Don't repair blindly，Because the truck is a whole，There is a problem with any link，will cause different or similar failures。
