Dongfeng well off K17 is always high water temperature these days, what is the problem?

<>. There are many reasons for the high water temperature of the engine, such as damage to the electronic components of the cooling system: thermostat, cooling fan, radiator poor heat dissipation, insufficient coolant, etc.

Second, check whether the antifreeze is missing, resulting in high engine water temperature. The circulation of the coolant, whether the circulation is not smooth. Secondly, you can also check that water temperature sensors, water pumps, thermostats, cooling fans, etc., may cause high water temperatures.

Third, the temperature is too high to cool down, and the engine is also unbearable. If the engine is left idle for a while, the constant circulation of coolant can still reduce the impact of high temperatures on the engine.

The engine prompts the treatment method of high water temperature:

Pull over, but don't turn off the engine right away. Because the temperature of the coolant is already very high, the cooling capacity has reached its limit, and if the ignition is turned off immediately, the boiling coolant will stop circulating.

First of all, let's see if the fan is still turning.

If it does not turn, first rule out whether the fuse of the fan is burned out.

If it is directly changed to the fuse of a fan, if it is not a fuse, it depends on whether the water temperature is less than the normal scale value.

If you add less antifreeze, it can be solved.

If a lot of this item is excluded, take a look at whether there is a problem with the pump, Dongfeng Xiaokang K17 has a large space, strong carrying capacity, enough power, large body space, and strong loading capacity.

The engine has a maximum torque of 83 Nm and a maximum torque of 102 Nm, mated to a 5-speed manual transmission, and the power is acceptable. The front disc and rear drum are braking systems and are equipped with ABS.

The well-off K17 is very cost-effective.

Hello, Dongfeng well-off.

These days, the water temperature is always high.

The following problems: 1. Insufficient coolant.

The water circulates for a long time when the engine is working.

It will cause the coolant of the engine cooling system to slowly lose, resulting in a lack of water in the water tank, if the owner does not check and add the coolant in time, it is easy to cause the engine water temperature to be too high.

2. The water tank is leaking.

The water pipe connected to the water tank is broken or not tightly connected, which will cause water leakage, which will block the water circulation, and in serious cases, cause the engine to boil.

3. The cooling fan is faulty.

If the cooling fan is damaged or the wiring is short-circuited, the fan works or the cooling fan rotates slowly, which will cause the heat of the engine to not be dissipated, and the water temperature of the engine will naturally rise.

4. Thermostat failure.

The thermostat is a device that controls the flow path of the coolant, and once it gets stuck or fails, the size of the engine cycle will inevitably be affected, and the heat of the engine will not be effectively dissipated.

5. The pump is faulty.

After the water pump fails, the water of the engine heat conduction cannot be circulated and updated in time, so the water temperature will rise rapidly after the engine starts, and the water temperature warning light on the instrument panel in the car will also be on.

If the water temperature is too high, it is commonly known as boiling the pot. Boiling the pot will cause deformation or even damage to the cylinder head and block.

When the temperature is high, it becomes difficult to dissipate heat from the water tank, the water temperature of the engine will rise to varying degrees, and the hose will be more likely to soften the cooling water.

Leakage, therefore, it is common for the water to be too hot or even to boil the pot while driving. The normal engine water temperature should be constant at 85-95 degrees Celsius.

When the water temperature is too low, the fuel can not be atomized well when it enters the cylinder, the power and economy are not good, and the matching gap between the parts is too large at low temperature, and the noise and vibration will be larger. When the water temperature is too high, the oil viscosity will become thinner, the lubrication strength will decrease, and at the same time, high-speed moving parts such as plugs and valves are more likely to deform, resulting in engine weakness. In severe cases, the expansion and deformation of the piston will strain the cylinder liquid cylinder and crankshaft.

The bearing dissolves and locks the crankshaft, etc., and the consequences are unimaginable. Therefore, for example, the water temperature gauge hand is close to the red zone.

Or if the water temperature warning light is on, you should immediately pull over and turn off the engine for inspection.

The water temperature of the car is a reflection of the working condition of the cooling system of the car, and the engine must run best at the appropriate high temperature of the company, which is suitable for the temperature, which can better make the fuel burn and reduce gas emissions. The main reasons for the high engine temperature are:

1. Insufficient coolant.

2. The cooling fan is faulty.

3. Circulating water pump failure.

4. Thermostat failure.

5. Poor heat dissipation of the water tank.

The phenomenon that the water temperature of the vehicle is too high and will be destroyed indiscriminately is.

1.The instrument cluster has an alarm indicating that the water temperature is high or the engine is overheating.

2.The engine cooling fan rotates at high speed, and the noise is high.

3.Engine knocking may occur.

4.In severe cases, it may cause the engine to burst and the engine cannot be started.

The high water temperature of the vehicle engine is a fault in the cooling system, and the thermostat, cooling water, electronic fan, water pump, water tank, water temperature sensor and other components are checked and repaired one by one.

There are many reasons for the high water temperature of the engine or even the "boiling", such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, and the coolant is not dry.

First of all, look at whether the fan is still rotating, if not, first exclude whether the fuse of the fan is burned out, if it is directly replaced with a fan fuse, if it is not a fuse, it depends on whether the water temperature is less than the normal scale value, if less plus appropriate antifreeze can be solved, if a lot of exclusion of this item, and then see if the pump is a problem of opening the year,

The car pin shouts that the water temperature is high, first of all, it is recommended to check the water tank thermostat first, if the thermostat is not faulty, it is often caused by the radiator or fan problem.

There are many reasons why the water temperature is too high (boiling): 1. There is a problem with the temperature control sensor switch (also called the sensor plug). 2. There is a problem with the water pump.

3. There is a problem with the thermostat (it cannot be opened normally). 4. The water tank is blocked (resulting in poor heat dissipation). 5. Coolant.

Insufficient. Problems with any of the above will cause the pot to boil (the water temperature is too high). In addition, the ignition time is not accurate, and the air-fuel ratio is not equal, which will cause the water temperature to be too high.

See if the fan is still rotating, if not, first rule out whether it is the fuse of the fan.

If it is not a fuse, it depends on whether the water temperature is less than the normal scale value, such as the slow spring fruit is less and the appropriate antifreeze is added.

It can be solved, if a lot of this item is excluded, take a look at whether there is a problem with the pump.

There are several main reasons for high idling:

1. The idle switch is not closed;

2. The idle control valve is faulty;

3. Air intake pipe leakage;

4. The gas distribution phase is wrong;

5. The injector is dripping or clogged;

6. The exhaust system is blocked;

7. The EGR valve is opened when idling.

Solution: 1. Adjust or replace the throttle position sensor;

2. Clean or replace the idle control valve, and use a special decoder to set the idle speed;

3. Find the leakage, reseal it or replace the relevant parts;

4. Check the timing mark and readjust the gas distribution phase according to the standard;

5. Clean and check the amount of fuel injected by each injector and confirm that there is no blockage or dripping;

6. Replace the three-effect catalytic converter;

7. Eliminate the carbon deposits on the EGR valve or replace the EGR valve.

Reasons for high water temperature:

1.The cooling fan is not spinning, and the cooling fan is malfunctioning.

2.There was a problem with the cooling medium, and the condensate ran out, causing the car tank to be too hot.

3. The thermostat is damaged.

It is recommended to go to 4S to adjust the idle speed. I often slack off and can't adjust myself! Computer-controlled! High speed has an impact on the engine, and fuel consumption will also increase.

If it is only a little higher, it should be because of the low temperature, the lubricating oil has poor fluidity, and the idle speed of the trip computer is adjusted higher in order to prevent the ignition, which is a normal phenomenon; If it is accompanied by irregular engine noise, it may be the cause of carbon build-up on the throttle or fuel injector;

When the engine idle speed is too high, the engine should be started first, and then the throttle arm should be controlled by hand to close the throttle. If the idle speed is normal at this time, the throttle tension spring is too soft and the tension spring should be replaced. If the throttle valve is closed by hand is ineffective, it should be checked whether the throttle shaft is loose or whether the throttle is tightly closed, if the throttle is not closed tightly or the throttle shaft is loose, it should be trimmed; If the throttle is normal, check whether there is a slight air leak under the throttle, if so, the air leakage should be eliminated, and if not, the idle speed should be further adjusted until the idle speed is appropriate.

The simple solution is to use a power-boosting fuel-saving semi-automatic idle motor.

Hello, one adjusts the idle motor, and the other cleans the throttle.

What's this called??? If you block the idle speed, it will be normal, and if you let go, the idle speed will be high. Air filter??
