Why is the water temperature high in neutral or traffic jams?

This is normal.

Car cooling is divided into two types: water-cooled and air-cooled (also known as air-cooled), low-end cars are air-cooled, high-end luxury cars are basically water-cooled, and water-cooled has passive water-cooled and active motor water pump circulating water-cooled (Porsche Cayenne.

That's it).

The car is water-cooled and is now basically active. When the car stops the reciprocating motor pump stops, the car starts to work once the motor pump starts, and the cold water and hot water will be circulated alternately to cool down, otherwise it will be cold and hot.

The solution is not to turn off the car when it is stuck in traffic, let the car idle, even if you get home or at your destination, let the car idle for 3 5 minutes and then turn off completely.

If the idle speed is still very high for more than 5 minutes, then it is possible that the circulating water pump is broken, or the circulating system.

If the tube is blocked or the circulation is not smooth, it is OK to change the tube.

By the way, water-cooled cars don't have fans, because there is a circulating water pump that is enough to cool down, and only high-end luxury racing cars are water-cooled and air-cooled, and it is only necessary in the case of more than or equal to 8-cylinder engines.

Lao Yang: I can't rely on this! Listen.

In the run-in, the clutch should be pressed before the brake is applied (assuming that it is not in neutral, it is not necessary to press the clutch in neutral), and you can coast in neutral. The water temperature can sometimes be as high as 100 degrees, which often happens when there is a traffic jam, if you feel that the wind at the air outlet is very hot, then turn off the air outlet (the air outlet has a knob, there is + and —, rotate it, put your hand on the air outlet to feel it).

Because the heat dissipation is not good when it stops there, the temperature is too high, and it is good to open it then, because the air cooling is dissipating the heat

An electronic fan can be added in front of the radiator.

Same as my Poussin, came back yesterday because of the traffic jam, the result was high temperature, leaned to the side of the road, opened the lid and found that the storage pot was cracked, at that time, there were people spraying steam near the lid of the kettle, afraid of scalding, and did not open it, no way, because of the old car, so the trunk was ready at any time with engine oil and coolant, and after waiting for two hours, the road was opened, and the storage tank was opened, and some coolant was added, and it was driven back in this way, and there was no high temperature, but the coolant evaporated quickly, and it could be driven back There must be potential safety hazards The lid is always impossible to prop up and drive, idle traffic jams, fans don't play much role, water tanks, it is estimated that the dust is protected, the car is driven, and the wind comes in from the air intake grille Air cooling also starts to work.

Damn, stepping on the clutch is stepping on the brakes, won't it increase the gliding speed of the car?

Who taught you to step on the clutch brake together, it is absolutely not okay, if you drive in winter, do you step on it at the same time?

Pretend to be a teacher, hey! Have you ever driven on ice and snow?

Step on the accelerator in neutral gear and the water temperature rises quickly. In the case of n gear, the engine is not involved in the drive, but in operation, which is equal to the usual acceleration of driving, the engine speed can reach 3000-4000 rpm, neutral refueling will not aggravate engine wear, belongs to the normal use range, N gear is neutral, if the time is not long, there is nothing to do, the engine speed at this time is about 4,000 to 5,000 rpm, and it will cost oil for a long time, which will cause the water temperature to be too high and cause the pot to boil.

N gear throttle hazardsWhen starting the car, the manufacturer stipulates that the gear can only be in the P gear and N gear, the engine will start, so the gas pedal in the P gear and N gear will not cause damage, in the case of N gear, the engine is not involved in the drive, just in operation, which is equal to the usual acceleration of driving, the engine speed is used to 3000-4000 rpm, and the neutral gear refueling will not aggravate the engine wear, which belongs to the normal use range, if you step on the medium and high speeds, suddenly hang from the N gear into the D gear, which will cause damage to the gearbox.

Summary. In this case, it is mainly because of your antifreeze circulation is not good, the common reason for high temperature may be that the pump is broken or the water tank is blocked, it is generally recommended that you do an inspection of the water tank first, you can clean the water tank, if it still doesn't work, then you have to check the water pump and thermostat.

The water temperature is high, and the water temperature will drop when the throttle is increased in neutral.

Nissan Teana. Hello, like this case, mainly because your antifreeze circulation is not good, the common reason for high temperature may be that the pump is broken or the water tank is blocked, it is generally recommended that you do a check on the water tank first, you can clean the water tank, if it still doesn't work, then you have to check the water pump and thermostat.

The upper and lower thermostats have been replaced, and the water pump is normal.

Wash the water tank with a kiss.

The water tank was also cleaned.

The water temperature sensor has also been replaced.

Looking at the data flow ,,, algebra under normal algebra slowly ** to more than 110 ,,, electronic fan rotates at high speed, and does not drop, like this case, mainly because your antifreeze circulation is not good, the common reason for high temperature may be that the water pump is broken or the water tank is blocked, it is generally recommended that you do a check on the water tank first, you can clean the water tank, if it still doesn't work, then you have to check the water pump and thermostat.

1. There are many reasons for the high water temperature of the engine or even "boiling", such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, insufficient coolant, etc.

2. Pull over, but don't turn off the engine immediately! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).

3. Of course, if it is an electric water pump engine, it will be better), too high temperature can not be cooled, 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.

4. Check whether the antifreeze is lacking, 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.

If you don't have a strong hands-on ability, you should go to the repair shop for an inspection.
