The reason for the high water temperature of the Mercedes Benz engine, what is the problem of the hi

The specific reasons for the high water temperature of the Mercedes-Benz engine are as follows:

1) The cooling fan does not rotate. The cooling fan may be controlled by a thermostat switch; It may also be controlled by a water temperature sensor.

2) Insufficient cooling medium. Antifreeze: High-end cars are required to be filled with antifreeze all year round; Water or distilled water: temporary substitute; The water tank cover is leaking.

3) The thermostat is damaged. If you want to remove the thermostat, you should plug the small circulation at this time, so as to ensure that all the coolant is dissipated by the water tank; When installing a new thermostat, you should pay attention to the water hole, such as Santana does not have a water hole, at this time, a 6mm drill bit should be used to drill a hole. One function is to be used as a marker; Another function is that during the heating process of the car, the temperature difference between the two sides of the thermostat is generated, so that the thermostat is accurately opened with the water temperature.

4) The water tank is clogged. External blockages should be removed with water or gas; Internal blockages affect coolant circulation and create pressure, which can result in two outcomes, one is a leaking water tank or the other is a particularly high water temperature at high speeds.

5) Pump failure. The impeller slips or gets stuck, causing the timing belt to break; The impeller is deformed.

6) Cylinder corrosion. The combustion chamber and the waterway are flushed, and at this time, the water will be drained from the drain pipe or white smoke will be discharged, resulting in a frequent shortage of water in the water tank; The waterway and the oil channel are flushed (the oil is white when there is water); The waterway and the waterway are rushed, resulting in poor heat dissipation of the cylinder block, especially at high speed; Blocked waterways.

7) Incorrect ignition timing (corrected with timing lamp) and excessive oil pressure.

Facing the engine, it can be seen at the rear of the engine on the right side, next to the throttle.

Reasons for the high water temperature of the car:

1. The cooling fan does not rotate, and the cooling fan fails.

2. There is a problem with the cooling medium, and the condensate is used up, which leads to the high temperature of the car water tank.

3. The thermostat is damaged, and the car can only be sent to the 4S shop for maintenance if this fault occurs.

4. Or if the water tank is faulty, replace the water in the water tank or replace the water tank.

5. The ignition method is incorrect, resulting in too high oil pressure.

6. If the pump fails, find a professional person for maintenance.

Solution: 1. If the water temperature is very high before starting the car, the car may not be easy to start, and there are many reasons for the high temperature of the car.

2. The cooling fan does not rotate, the coolant is insufficient, the water temperature gauge is faulty, the water tank is blocked, etc., which may cause the high temperature of the car.

If the water temperature gauge is normal, when the temperature reaches the red warning line, slow down, and when it is safe to do so, pull over to the side of the road, taking care not to turn off the engine.

3. Do not pour cold water on the engine, wear gloves and gently unscrew the lid of the water tank, wait for the water vapor to be slowly discharged, and after the pressure of the water tank drops, add cold water or antifreeze.

4. Regularly check the body to ensure that there is no dirt around the water tank, which causes the heat dissipation capacity of the water tank to decrease.

Hello, Liang suspects Mercedes-Benz cars these days always have a high water temperature.

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) Pump failure.

After the water pump fails, the water of the engine heat conduction can not 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 buried in the key.

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, and the water temperature of the engine will rise to varying degrees, and the hose is 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. Normal engine water temperature should be constant at 85-95 degrees Celsius.

When the water temperature is too low, the fuel enters the cylinder and cannot be atomized well, the power and economy are not good, and the matching gap between the parts at low temperature.

If it is too large, the noise and vibration will be larger. When the water temperature is too high, the viscosity of the oil will become thinner, the lubrication strength will decrease, and at the same time, the high-speed moving parts such as the piston and valve are more likely to deform, resulting in engine weakness. In severe cases, the expansion and deformation of the piston will strain the cylinder, 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.

Hope it helps!

Mercedes-Benz cars, these days are always hydroplaning state temperature high and coarse, because the sale of the car caused by the failure of the town air cooling system, you should go to the car maintenance center in time to find the master to help overhaul it.

Check whether the antifreeze is available first, because the antifreeze is not only antifreeze, but also plays a role in stabilizing the water temperature and preventing the pipe from corroding.

Summary. Dear Kiss Glad to serve you Mercedes-Benz water temperature over 90 degrees is normal, don't worry, you can drive with confidence. The normal water temperature of the Mercedes is as follows:

1.Generally normal operation, Mercedes-Benz engine water temperature in 90-105. 2.

The new car just mentioned is always 90 while driving, and he will be 100 when the car stops.

The new car just mentioned is always 90 while driving, and he will be 100 when the car stops.

Dear, normal.

The water temperature of the Mercedes 271 engine is 90 degrees normal, antifreeze after the vehicle starts.

The temperature rises rapidly, the pointer reaches 90 degrees, and the heat exchange equilibrium antifreeze temperature rises no longer before the temperature rises, and generally speaking, the best start is when the temperature reaches 90 degrees. In normal operation, the water temperature of the Mercedes-Benz engine should be mostly between 90 and 105 degrees Celsius.

Because in some cases, the water temperature is normal at 65 to 90 degrees Celsius and 105 to 120 degrees Celsius, as long as it does not stop in this low or high temperature range all the time, this is the Mercedes-Benz thermostat according to the engine load, engine speed.

How it works

Intake stroke crankshaft.

The piston is driven from top dead center to bottom dead center, at which point, the intake valve opens and the exhaust valve closes. During the movement of the piston, the cylinder volume gradually increases, forming a vacuum.

The combustible mixture chamber is then sucked into the cylinder through the intake valve until the piston reaches the bottom dead center and ends when the intake valve closes.

Although now pure electric vehicles.

Now the speculation is hot, but the current power of the car is still the internal combustion engine. The so-called internal combustion engine is the mixing of fuel and air inside the engine, and the combustion produces heat energy and converts it into mechanical energy.

The water temperature of the Mercedes-Benz car is 90 degrees, and the electronic fan begins to turn, and the water temperature is 140 degrees before the pot is boiled. The heat dissipation demeanor fan is opened to several manufacturers, and the standards of each system are inconsistent.

But the fan channel is generally divided into high and low gear, low gear starts at about 87 degrees, if the fan is rotating at this time, and the water temperature continues to rise, after reaching 95 degrees, the high-speed air return fan will start to work, the low-speed has 87 and 85 degrees, and the high-speed has 95 and 97 degrees, which varies from model to model.

Hello, the Mercedes Benz is 140 water temperature before the pot is boiled, at 120 hours, the electronic fan starts to work.

The Mercedes was 140 water before the pot was boiled, and at 120, the electronic fan started working.

My Mercedes-Benz 260 drove more than 7,000 kilometers on the high temperature, just out of the warranty period, maintenance, replacement pump four s shop to 5,000

Normally, the water temperature is 90 degrees Celsius.

What is the reason for the high water temperature of Mercedes Benz? Hello dear, 1Where the oil returns too dirty (solidification, etc.) causes poor heat dissipation in the engine and overheating the engine.

2.Extreme driving, continuous high-intensity and high-speed driving, braking, and then high-speed ......3.Silent failure of the cooling fan or other failure of the cooling system.

4.Filled with the wrong coolant or insufficient coolant, etcExtreme weather.
