Vehicle Seasonal Maintenance Precautions Change Engine Oil According to Temperature

Most car owners maintain their cars according to their mileage. Nowadays, the editor may subvert everyone's traditional concept. In the seasons of alternating cold and hot, it just happens to catch up with spring and autumn. For some car owners, even if the prescribed maintenance mileage is not reached, they still need to maintain their beloved cars. Especially in northern China, riders with lower temperatures in winter should pay special attention.

Some people may ask why maintenance is needed even if the mileage is not reached. The main secret lies in the oil. People may not pay attention to the maintenance of their cars at ordinary times. No matter what brand of oil it is, there will be some labels on the packaging barrel. For example, 5W/40,0w/30,10w/30, etc. In fact, these labels are directly related to seasonal changes.

The smaller the value before W, the smaller the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable high temperature. The following numbers generally include: 20, 30, 40 and 50. The larger the value, the greater the viscosity.
The low temperature resistance of 5W engine oil in winter can reach about minus 30 degrees Celsius, and the low temperature resistance of 0W engine oil can reach about minus 40 degrees Celsius. These two grades can basically meet the low temperature conditions in most parts of China. However, there are some extremely cold areas in Northeast China, where the low temperature can usually reach minus 30 degrees or lower. This is why AutoLiuma reminded some riders in the cold areas of Northeast China at the beginning of the article to update the maintenance of their cars in time. If the last time you changed the oil marked with 5W or 10W, you must change it, otherwise in winter, the poor fluidity of the oil will cause serious wear and tear on your car engine and shorten its service life.

In addition to refueling, you should also clean the interior of the car after entering autumn

Due to the hot weather in summer, car owners often open the windows to cool off. As the air quality is getting worse and worse, there is dust everywhere. So there will be a lot of dust in our car. High temperatures in summer are also prone to breeding bacteria, so it is also necessary to clean the interior of the car in autumn. In this regard, Komi Car Service has summarized several places that need to be cleaned. Carpets are places where bacteria are easy to breed. You can use a foam cleaner to brush all the carpets in the car, and the appearance of the new car can basically be restored. In addition to low carbon, there are also dashboards, steering wheels, center consoles, seats, etc. These positions can basically be wiped once with a semi-dry wet cloth.

Tire inspection and replacement are also particularly important

Many car owners reduce tire pressure to prevent tire blowouts caused by high temperatures in summer, but this is actually a misunderstanding. A maintenance technician who has been engaged in the automotive repair industry for many years revealed that the reason why many tire blowouts occur in summer is that the car owners themselves reduce the tire pressure. Because most tires have a lot of steel wire inside to pull the entire tire. When driving with insufficient tire pressure, due to irregular deformation of the tire (tire deflection), the steel wire inside the tire is constantly deformed, causing the steel wire temperature to rise sharply and break easily. Coupled with the increase in tire temperature during driving, the possibility of tire blowout increases.

In this regard, car owners should carefully check the tire pressure, which should not be too high or too low. Generally, the tire pressure should be 2.2-2.5. If there is a spare tire, the tire pressure is higher because the spare tire is often in a state of insufficient pressure during use. Therefore, the tire pressure should be appropriately increased, generally around 2.5-2.8.

In autumn, it is also necessary to maintain the paint surface of the car body

Due to the high rainfall in summer, if there are deep scratches or scratches on the car body, it is easy to rust in autumn if it is not handled in time. What the car owner needs to do is to spray paint the scratched parts. The role of paint is not only beautiful, but more importantly, it has anti-rust function. The rain acid in the summer rain, coupled with the strong sunlight in summer, will cause corrosion and oxidation on the paint surface. Car owners can choose from cleaning, polishing to waxing, glazing, or coating according to the actual situation of the car body.

The focus of car chassis maintenance in autumn is rust removal

On the one hand, the metal material of the chassis is prone to rust after burning in rainy season or high temperature weather, which hinders driving safety. Therefore, it is necessary to remove rust from the chassis. On the other hand, during the rust removal process, you can check whether there are scratches on the chassis, screws fall off, etc.

Maintenance of heating pipes and fans

In autumn, when the weather gets colder and the temperature drops, white frost will appear. In this season, pay special attention to whether the defrost outlet under the windshield has normal air volume and sufficient heat. If there is a problem, it should be solved in time, otherwise, it may cause unsafe factors for your driving.
Before the season change, it is necessary to maintain your car, which can not only improve the performance of the vehicle, but also ensure our driving safety.
