In the twinkling of an eye, the autumn has been cool, I do not know that the use of air conditioning in the vehicle has been adjusted from A / C to warm air gear. With the use of warm air conditioning, it is found that the air conditioner is filled with a sour taste, which greatly reduces people’s sense of driving. I have also tried to turn on Aamp C to use air conditioning to check. The sour taste has obviously diluted a lot after Amax C is turned on, but when the warm air is turned on, I can obviously feel the sour smell coming from my nostrils. After consulting the relevant people, it is said that it is the problem of the air conditioning filter element, which may have not been replaced for a long time, leading to the occurrence of this peculiar smell.
When I went to the store for maintenance last month, the original intention was to replace the air conditioner filter element, but after looking at the surface condition of the filter element, I thought it could still be used, so I didn’t change it. It seems that I was hasty. As to whether it is caused by the odor caused by the filter element, we will not know until it has been replaced.
When writing this post, the aftertaste of that sour and refreshing taste still makes me a little at a loss.
I usually pay attention to the use of air conditioning, and I washed the air conditioning pipes this summer.
As a car lover, you must have some glass water and air-conditioning filter elements in your car for a rainy day. I was going to replace this air conditioner filter element myself, but my No. 25 spline tool was missing, which made me a little embarrassed.
Although I have my own air conditioner filter element, I have no tools, which means I can’t change it. In the end, I can only turn to the shop master for help in replacing the filter element.
The shop was busy at the weekend, and the workshop was full. The master helped me change the air conditioner filter element outdoors.
The difference between a professional and an amateur is obvious. I was obviously clumsy when I opened it.
The position of the filter element of the air conditioner can be seen when the cover plate is opened.
Filter element has been removed.
I took the filter element close to my nose and smelled it. I felt that there was indeed a sour smell on the filter element.
If you look at the filter element removed from the car alone, it feels good in all aspects, but it is not good when compared. Even if the picture above is not marked with the new and the old, you can see the difference with the naked eye.
When the air conditioning filter element is installed, there is a positive and negative direction, such as the wrong direction of installation, it will directly affect the role of the air conditioning duct. The arrow in the red circle above is facing in the positive and negative direction of the installation. (whether the air conditioner filter element is an original factory or a secondary factory, there will be arrows to indicate the direction.)
The new filter element has been installed in the filter element frame.
If it hadn’t been for me to take pictures, it would have been installed by the master, which would have taken a lot of time.
After the filter element has been installed, the master is fixing the cover plate bolt.
This water bar must be installed, or the engine compartment will be flooded easily.
Don’t think I’ll be happy when I change the filter element. Don’t worry, there are other things to do in the store.
At the beginning of the article, we mentioned cooling, some facilities and maintenance of vehicles, we must take precautions in advance, such as the use of glass water, we must use glass water with anti-freezing.
If the glass water with anti-freezing function is not used in winter, it is easy for the kettle to freeze and the motor, fuse and so on. As for how to distinguish whether the glass water has anti-freezing, it depends on whether the package has a freezing point, and it can also be identified by smelling it. All the glass water with anti-freezing function will contain alcohol, and there will be a smell of alcohol.
Glass water is an essential replacement in winter, and another thing that can not be ignored is tires.
My habit is that the tire pressure is 2.2Bar in summer and 2.4Bar in winter. We all understand the principle of hot expansion and cold contraction. The tire is made of rubber for the same reason.
A few days ago, I knocked on the chassis and asked the master to check it for me. Fortunately, Heilang did not have any damage.
Garrulous also said a lot, today’s filter element replacement and vehicle inspection is over.
The sour taste mentioned earlier has disappeared without a trace after I replaced the air-conditioning filter element. It seems that it is really the problem of the filter element. You can’t just look at the surface, just like this filter element. It looks good, but in essence it has lost its function.
The air conditioning filter element of PM2.5 contains carbon particles, which will lose its original function after it reaches saturation state. If it is not replaced in time, the filter element will have the opposite effect.
With regard to the replacement of the filter element, it is also very clear that we should not only look at its surface, but also look at the actual situation.
In addition, the maintenance of vehicles in winter, such as the glass tire pressure mentioned above, must be paid attention to.
After using the vehicle air conditioner at night in winter, a few minutes before you arrive at your destination, remember to open the window so that the temperature inside the car is the same as outside, so that the glass inside the car will not be foggy and will frost and ice seriously. In winter, we must pay attention to the temperature difference between inside and outside the vehicle, use warm air for a long time, and remember to switch between internal and external circulation or open windows for ventilation.
There is still a lot about the use of vehicles in winter. That’s all for today. We will have the opportunity to discuss with each other in the future.
