Winter maintenance is important. Experienced drivers say: Otherwise, you'll have to spend money on repairs.
Actually, drivers should all understand that in the cold and freezing conditions of winter, cars can encounter all sorts of problems, which also brings a lot of troubles to the drivers. Therefore, drivers must carry out some necessary maintenance and protection for their beloved cars.
This can help them reduce trouble. In winter, everyone knows to prepare winter clothes for themselves, and we should not forget to prepare winter maintenance for our vehicles. So, what measures need to be taken in winter?
▎ Maintenance and inspection of the fuel system
Some friends may feel that fuel prices are relatively high, so they choose to use lower-grade fuel. In fact, lower-grade fuel has the characteristics of insufficient combustion value and high sulfur content, and it contains many impurities. On the other hand, many consumers may consider that the price of original factory fuel filters is high, so they use ordinary diesel filters available in the market. What they may not realize is that not only is using lower-grade fuel an issue, but using ordinary diesel filters cannot properly filter the fuel.
▎ Maintenance of the brake air system
Every winter, temperatures in the north get even lower. If the vehicle’s air system is not inspected and maintained in time, when the cold winter truly arrives, the air system may freeze. Therefore, before winter comes, it is essential to replace the air dryer in a timely manner and check whether there is water in the air tank. If necessary, add anti-freeze agent and coolant to the air system. If the system freezes while transporting goods, it is the driver who suffers.
▎ Check the battery and electrical system
As everyone knows, the battery’s charge decreases under cold winter conditions. When the temperature is very low in winter, starting the vehicle is more difficult compared to summer, and more electricity is consumed. Due to thermal expansion and contraction, old wires and connectors need to be checked and treated to avoid troubles caused by poor electrical contact.
▎ Check or replace antifreeze
The function of antifreeze is to cool, prevent corrosion, and prevent freezing. In northern regions during winter, the temperature can easily drop below 0°C, sometimes even reaching -30°C. At this time, antifreeze is needed. Of course, antifreeze also has a validity period.
▎ Check the heating system
A car’s heating system is essential in winter. Without it, in southern regions it might be more tolerable, but in the north, it would be very difficult for people to endure such cold conditions.
▎ Check the windshield wiper and spray system
In winter, there is more smog and dust, so the frequency of using wipers increases. Like antifreeze, although in summer you can use water or cleaning fluids as substitutes, in winter these alternatives freeze.
▎ Check the entire braking system
With more rain and snow in winter, the roads are slippery, and the braking system must meet higher requirements. Therefore, be sure to inspect the braking system.
▎ Adjust tire pressure
In hot summer conditions, tire pressure is set lower, but in winter it can be increased. This ensures sufficient tire load compared to summer, because tires and the air inside them are susceptible to thermal expansion and contraction.
Therefore, truck maintenance measures must be taken in winter. Experienced truck drivers know: otherwise, get ready to spend money on repairs. These tips are worth paying attention to.
