Arrive summer air conditioning use of a lot of, drive a car to want to open air conditioning basically all the time by day, and the change of air conditioning filter element, it is air conditioning system maintains in the most basic one. The function of air conditioning filter element is known to all, is to filter the air into the car, so that we breathe fresh and clean air. Some people also say that we don't need filters to breathe outside, so why do air conditioners need filters to let us breathe? This is because the suction generated by the blower operation is relatively large, and the area of the air inlet is relatively large. As long as there is a little cotton wool and dust around the air inlet, it will be sucked in. In the car, the space is narrow, the air flow is poor, and the probability of dust being breathed into the body by us is relatively large. In other words, if you don't filter it, the air inside the car is probably worse than the air outside. ...

Brake pad is an important part of brake system. The main working principle of the brake is to use the brake pad and brake disc and tires and the ground friction, a huge friction to stop the car, after constant friction brake pad will wear thinner and thinner. How often are the brake pads changed? Theoretically speaking, the service life of the front brake pad is 20-40,000km, while the service life of the rear brake pad is 60-100,000km. But different drivers have different driving habits, so it depends on how worn the brake pads are. I suggest that, on average, the front brake pads should be checked every 30,000 km and the rear brake pads should be checked every 60,000 km to decide whether to replace the brake pads according to the professional scientific test results. Everyone knows that the brake pads must be replaced when they are worn out, but if they are not found in time to continue using the car, they will wear out the brake disc as well. The brake pads are fixed...

The purpose of spark plug is to ignite, when the cylinder is running to the top dead center, through the spark plug ignition, gasoline can be burned to produce energy. Therefore, the better the spark plug ignition ability, if the spark plug ignition ability is poor, will miss the best ignition time, leading to incomplete combustion of gasoline, and the gasoline after combustion is not fully used to do work. The intuitive feeling is that the car has poor power, high fuel consumption, and there will be a lot of invisible carbon accumulation. Replacing spark plugs is also a regular maintenance item. It needs to be replaced regularly. How many kilometers should be replaced? What symptoms of the car must be replaced? There is a general mileage, the ordinary spark plug about 40,000 kilometers replacement, platinum plug 80,000-100,000 kilometers replacement, the normal situation of the car to follow this mileage is ok. There are a lot of maintenance manual recommended replace...

The battery of the remote control key of the car can be used for about two to three years under normal circumstances. When the power is out, it can be replaced by after sales. 1. In general, the remote control key will not suddenly run out of power, but will be indirect. You can only open the door when you find that you need to be very close to the car, or there is no response when you press the key several times, then you should consider changing the battery. 2. If the time limit is exceeded, the signal is likely to be weak, but the specific time of power consumption is also related to the storage at ordinary times. For example, if we put it close to the mobile phone or computer TV, the battery will consume a lot, because it will send some electronic waves to the outside at any time. 3. The car key is not a secret accessory, the battery is our common button battery, but improper operation will cause circuit board damage, please be careful operation.

 Almost every family now has a car, but very little time is spent on it. However, the car does not run for a long time, and there will be a lot of minor problems when it is used. Sometimes, the car is not using until broken ,is parking too long until broken. So what are some of the injuries from leaving your car unattended for too long? First, if the car has not been started for a long time, the storage battery in the car will lose power for a long time, and its capacity will be reduced almost every day, which is very bad for the storage battery. Over time, will also lead to problems in the entire circuit system, so it is easy to start the fire, can not start up. But also storage battery surface will also occur some oxidation phenomenon, affecting the normal work of the battery, reduce the actual life. Park if it is short, as long as no more than half a month, the new battery is full of problems, the old battery should not be more than 1 week, if more than a month to be not moved,...

Changing the oil isn't that complicated. Once you master a few key steps, you can complete the whole process in 20 minutes. Preparation: Before replacing, you may need to prepare a floor jack, safety rack, wrench and funnel. Before starting the replacement, check the underside of the car to make sure you can remove the filter. Check the oil capacity of the vehicle and the location of the drain plug in your user manual in advance. If your car has a cold engine, run the engine for a few minutes to heat the oil, which helps loosen up pollutants in the oil and allow them to flow into the drain pan. However, do not attempt to drain the oil after starting the engine and allow it to cool for about ten minutes to avoid burning your hands and allow the oil to flow into the pan as much as possible. Replacement steps: 1. Use a ramp when changing oil You can drive your car on a ramp, or use an inexpensive floor jack and a set of jack holders. Then shake the car from side to side to make sure i...

Talk about some of my own views. The brake problem is a part that every car owner cares about very much, because it is related to the safety of driving. When enjoying a convenient and fast lifestyle, safety is the first and must be guaranteed. Therefore, more checks should be made on the braking system in daily driving to ensure the safety of drivers. After the brake oil is used for a long time, the leather bowl and piston in the brake pump will be worn, resulting in the brake oil turbidity, so it needs to be replaced to ensure the normal use of the brake system. Brake oil is very important for the brake system, when choosing brake oil, you should choose the same size as the original car, the big brand, quality assurance Boston (BSD) brake oil. If it is unqualified, the quality of the general brake oil, will rot the brake pump plug, the effect of the brake will also have an impact. There was once an experiment on brake oil, in which a cup of water was poured into the brake oil. In an i...

 In general, for all cars, the tire pressure is generally no less than 1.8bar and no more than 2.6bar. Now, many cars can reach 2.8 and 2.9. But what you need to know is that every car has a different standard. The tire pressure of each model will be written on the co-pilot's nameplate. You can read the co-pilot's nameplate to find out what the normal tire pressure of your car should be. The bigger cars have bigger, wider tyres, so the pressure is slightly higher. We should also identify which factors also affect tire pressure: 1. Seasonal factors. The temperature of the external environment will also affect the tire pressure. The pressure will be slightly higher in winter and slightly lower in summer, generally with a difference of plus or minus 0.2. Therefore, it is generally recommended to raise the air pressure by 0.2 bar in winter based on the standard tire pressure. In summer, when the car is parked in the open air, the air pressure can be about 0.1 bar lower than the sta...
