Suddenly winter arrived overnight, dropping below 0 degrees: The most comprehensive guide for trucks to survive winter.
It is not yet the autumn equinox, but Heilongjiang has already dropped below 0℃. Each region of the Daxing'anling in Heilongjiang has welcomed the first snowfall of autumn, and the lowest temperature in Mohe City has also fallen below 0 degrees.Summer has passed, and a cold wave is coming. Drivers should check these parts on the truck in advance to prevent problems before they arise.▎High-quality diesel refueling in advanceFirst, let's popularize the concept of pour point. The pour point is an important indicator used to evaluate the flowability of diesel; it indicates the lowest temperature at which the fuel can be delivered without heating. The pour point of diesel refers to the highest temperature at which the oil product loses its flowability under specified conditions.
Technical Requirements and Testing Methods for Automotive DieselUnlike gasoline, which has a freezing point of -60 degrees, ordinary No. 0 diesel has a freezing point of only 2 to 3 degrees. According to the 'Technical Requirements and Testing Methods for Automotive Diesel,' the diesel number directly corresponds to its freezing point. However, diesel will inevitably absorb moisture during actual transportation, so it is best to use a higher grade when refueling.1. No. 5 diesel is suitable for use in temperatures above 8°C;2. No. 0 diesel should be used when temperatures are not lower than 4°C;3. No. -10 diesel should be used when temperatures are not lower than -5°C;4. No. -20 diesel should be used when temperatures are not lower than -14°C;5. No. -35 diesel should be used when temperatures are not lower than -29°C;6. No. -50 diesel should be used when temperatures are not lower than -44°C.● Remember to replace antifreeze that has been mixed with water.
The main function of antifreeze is to prevent freezing. The freezing point of regular water is 0 degrees, while the freezing point of antifreeze is usually around -30 degrees, preventing the coolant from freezing and affecting the vehicle's cooling system when parked in the cold winter. If you poured water into the radiator during an emergency in the summer, please replace the antifreeze before the arrival of winter. In addition to antifreeze, it's best to check the windshield washer fluid; otherwise, if the windshield is dirty and you can't spray the washer fluid, it can be very dangerous as you won't be able to see the road. ▎Brake air circuit Fuel pipeline Check in advance
Everyone is familiar with the drying tank; it is used to filter moisture from the air in the gas circuit to prevent corrosion of the gas storage cylinder and various pumps and valves. Whether the drying tank functions properly directly affects the performance of the brakes.After a humid and scorching summer, the lifespan of the drying tank has basically come to an end. To ensure safer operations and profits, it is important to timely check the condition of the drying tank.
In addition, everyone should check the exposed spiral pipes in the air system for flexibility before winter arrives. If there are any cracks or wear, they should be replaced as early as possible.Having talked about the air system, let's move on to the oil system. Water is a common contaminant in diesel, which can shorten the lifespan of the engine. Moreover, diesel has the property of absorbing moisture, so diesel filters are designed to separate oil and water.
Before the arrival of winter, check the fuel filter, change it in time when the mileage reaches, check the oil-water separator in time, and drain the filtered water promptly.▎In low temperatures, the battery is prone to failure.
Whether it's a storage battery or a power battery, the low temperature performance is not as good as when the temperature is around 20 degrees. In winter, with lower temperatures, starting becomes more difficult and power consumption increases. If the battery is old (typically between 3-5 years), it's best to check the battery performance in advance to avoid being unable to start.● Editor's NoteAs the old saying goes, a truck is seven parts maintenance and three parts repair, so it's important to take good care of it and perform maintenance early. Don’t wait until you and your cargo are stranded in the cold regretting it.
