If you don t turn on the air conditioner, the water temperature is high, and when you turn on the ai

If it doesn't run, the water temperature is high if you don't turn on the air conditioner, because the electronic fan doesn't run and can't dissipate the engine, when you turn on the air conditioner, the cooling fan will not stop running, so the engine can dissipate heat and the water temperature will not be high. But when you don't turn on the air conditioner, the fan turns again when the water temperature is high, and then stops again when the water temperature is normal. Specifically, there are the following aspects: first, you need to check whether the water tank is not well dissipated and blocked, or the fan is not running, or there is a problem with the water temperature sensor.

When testing the fan, you should also pay attention to some models, he is the water temperature and air conditioning is the same electronic fan, and some car air conditioning and water tank cooling are separated from the two electronic fans, if you are not a professional maintenance personnel, I suggest that you go to a professional maintenance shop to let him test for you, if my help to you, please accept.

1. The water temperature will be high when the thermostat is rusted and normally closed!

2. The first look at the thermostat, the second look at whether the pump return wheel is damaged, and the third look at whether the water tank is too dirty, especially whether the outside of the water tank is blocked by mud.

3. Don't think that the water tank won't open in winter, it's common for the water temperature to be high in winter. Finally, you take a look at the fan switch again to see if there is a problem. The location is at the bottom of the tank, there is a wiring plug.

As soon as the car turns on the air conditioner, the water temperature will be high, which should be a problem of poor heat dissipation.

After air conditioning, the engine drives the air conditioning compressor, and the engine load increases.

The start of the air conditioning condenser fan, the air conditioning fan, the compressor electromagnetic clutch and other components increase the load of the generator, so the generator should increase the output power, so that the operating resistance of the generator also increases. In the end, it is the load on the engine that increases.

The power is low when the air conditioner is turned on, and you need to press the throttle heavier while driving, or drive in a lower gear, or increase the load on the engine.

The air conditioning condenser is located in front of the engine radiator, and the two are next to each other. The temperature of the condenser can reach 60-70 degrees Celsius when working, which is equivalent to adding extra heat to the radiator and reducing its heat dissipation capacity.

Coolant circulation failure.

The coolant must be circulated to take the heat out of the engine and dissipate it. If the coolant is not circulated properly, it can also lead to insufficient heat dissipation and high temperatures. There are several reasons that affect coolant circulation failures:

Pump failure. The water pump is the power source for coolant circulation, and it is difficult for the coolant to circulate and dissipate heat without a water pump. Common faults include damaged pump blades and loose pump spindle. The most obvious sign of a broken pump is that there is no warm air.

There is air in the cooling system.

If there is air in the cooling system, the coolant will not circulate properly or even not circulate properly, so you need to open the air exhaust screw to try to exhaust the air.

First, as soon as the car turns on the air conditioner, the water temperature will be high, which should be a problem of poor heat dissipation.

2. Troubleshooting and treatment methods:

1. Check whether the electronic fan is working properly and whether the air deflector is damaged. If there is a problem, the ventilation and heat dissipation effect will not be effective when parking.

2. Whether the outside of the radiator and condenser is dirty, if it is cleaned, it will be fine.

3. Check whether the water temperature sensor is normal.

4. Clean the radiator of the water tank.

5. Check the thermostat.

Landlord, may be your vehicle used for a long time, on the one hand, the cooling system heat dissipation function is poor, resulting in high engine temperature, on the other hand, the main reason is that the car is older, the engine power declines, at high speed, the engine is often kept working under heavy load conditions, which must cause the engine water temperature to be too high. It is recommended that if you want to completely solve the problem, you should overhaul the engine, otherwise, do not drive at high speeds.

Because the air conditioning pump is driven by the engine, when the air conditioner is turned on, the load on the engine will increase, causing the engine temperature to rise. If the engine temperature rises beyond a reasonable range, it means that there is a problem with the engine cooling system, which may be due to the fact that the radiator of the radiator in the radiator of the water tank in front of the engine is blocked by dirty things, resulting in poor heat dissipation, or it may be that the engine interior has too much scale caused by the long-term use of inferior antifreeze, resulting in poor heat dissipation

If you don't go on the water, you have to check whether there is leakage or air resistance in the pipeline, or whether there is a problem with the water pump, of course, the electrical automatic control system also needs to be checked, because air conditioners are automatic control products.

Water-cooled air conditioning refrigeration, all rely on a self-priming water pump water supply, there are many reasons for the failure of the water, the first step is to check whether the power supply is sent to the pump motor, whether the pump motor is running normally, but also to consider whether the pump is damaged or that part of the air leakage, mainly check whether the water inlet is sealed, if the water inlet pipe leaks, it can not pump up the water.

If the water of the water conditioner does not come, first check whether the water pump of the air conditioner is running normally or the water outlet, whether it is blocked by foreign objects, and whether there is a leak in the pipeline.

If the water conditioner does not come to the water, first check whether the pipeline filter of the pump is dirty and blocked, clean the filter, and the poor sealing of the check valve is easy to lead to check, or there is air in the pump body, which needs to be discharged.

Water, air-conditioned water doesn't come what's going on? I think the water air conditioner on the water does not come, maybe the air conditioner is broken. Or the pressure valve on the water is broken. So the water does not come.

Check out your pump line parts! 1.The water pump pipeline filter is dirty and blocked, and the filter is cleaned 2Check valve seal is poor, disassemble to see the reason, if damaged need to be replaced3There is air in the pump body to be vented.

Maybe you have a good relationship, there are many people you know, and there are many people who have a good relationship with you, but even if you are a family member who gets along day and night, or even a close lover, you may not be able to talk to him whenever you want, you can say whatever you want, and you don't have to worry about being rude, you don't have to blame yourself, and you don't have to be afraid of being cold and reprimanded.

Sometimes, turn on the mobile phone, turn over the names one by one, and how many people can make you feel at ease and calm, you can go to disturb, you can go to talk freely anytime and anywhere?

If you have the right mindset, you'll be in a good mood, and if you're in a good mood, you'll be happy.

Summer is coming, the air conditioner is used frequently, and my G10 encountered such a situation! Whenever there is a traffic jam, the water temperature will be high when the air conditioner is turned on, but after the traffic jam road is normal, the water temperature will be normal again! The water temperature rises by one level, and every time I feel a little panicked!

There are several reasons for the high water temperature of the engine: 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.

Buy a car, use a car, maintain a car, repair a car, and listen to Chen Gong talk about cars.

First, as soon as the car turns on the air conditioner, the water temperature will be high, which should be a problem of poor heat dissipation.

2. Troubleshooting and treatment methods:

1. Check whether the electronic fan is working properly and whether the air deflector is damaged. If there is a problem, the ventilation and heat dissipation effect will not be effective when parking.

2. Whether the outside of the radiator and condenser is dirty, if it is cleaned, it will be fine.

3. Check whether the water temperature sensor is normal.

4. Clean the radiator of the water tank.

5. Check the thermostat.

The water temperature is low when the air conditioner is turned on, and the water temperature is normal if the air conditioner is not turned on.

Dear, hello, I'm glad to answer for you: The water temperature is low when the air conditioner is turned on, and the water temperature is normal if the air conditioner is not turned on? A:

There are two cooling coils in the front of the car, one for the engine cooling water pan and the other for the air conditioner. The arrangement of the two discs will overlap partially, and there will also be different fans for cooling. It is likely that the fan of the cooling engine is not rotating, and after the air conditioner is turned on, the fan of the cooling plate of the air conditioner is running, which assists in the cooling of the engine branch flushing tray and lowers the water temperature of the car.

In general, the water temperature can also be improved when the car is traveling at high speed, because the moving car will naturally have a forced air flow to cool the water pan. I hope mine can help you, I wish you a happy life, if I have help to you, please give me a 5-star thumbs up, thank you for your support to me.

Summary. This is normal, there is a water temperature detector in the car's radiator tank, and when the water temperature rises to a predetermined value, the fan will intervene to cool down, so it will make its temperature drop. The temperature rises slowly after the air conditioner is turned off, so it returns to normal.

The water temperature is low when the air conditioner is turned on, and the water temperature is normal if the air conditioner is not turned on.

This is normal, there is a water temperature detector in the car water tank, when the water temperature rises to a predetermined value, the fan will intervene to cool down, so it will make the temperature drop and feast. The temperature rises very slowly after the air is turned off, so it returns to normal.

Excuse me, but please go into more detail?

The functions of automatic air conditioning include automatic adjustment of temperature and humidity in the car, automatic control of return air and air supply modes, control of the stove, operation mode and air change volume, etc. The electronic control unit will make the air conditioning system run automatically according to the sensitive setting of the driver or passenger through the buttons on the air conditioning display control panel, and adjust the air supply temperature and air supply speed in time according to the signals input by various sensors, so that the air environment in the car can be kept in the best condition.
