Antifreeze first move
Timely replace the lubricating oil to ensure smooth operation of the parts. After the climate changes, the viscosity of the lubricating oil will also change, which will generally aggravate the wear of the parts, resulting in varying degrees of damage to the engine and other important parts. The engine oil has high requirements for automobile lubrication in winter, and the lubricating oil is divided into winter lubricating oil and summer lubricating oil, Experts suggest that winter lubricating oil should be replaced as soon as possible. Moreover, whether in Guangdong or in the north, the lubricating oil should be replaced. In particular, the engine oil with long service time, black color and poor adhesion should be replaced to ensure smooth start-up and operation of the engine.
Experts also suggest that high-scale gasoline can be replaced in winter. If you usually use No. 90 gasoline, you can change it to No. 93 gasoline. Because the ambient temperature of vehicles in winter is lower, the ignition point of using high-scale gasoline is higher, and the ignition ability can be stronger.
Antifreeze second move
Replace the engine antifreeze. It's easy to ignite in ice and snow. You need to check the antifreeze when driving in winter. The amount of antifreeze should be appropriate. The engineer suggested that the antifreeze of the engine should be replaced, especially the mixed antifreeze (especially those added with water in summer) must be replaced.
When cars from Guangdong arrive in the north, if the antifreeze concentration in the engine cooling water is too low, the engine water will freeze, causing the vehicle to fail to start in the morning. Therefore, it is necessary to increase the concentration of antifreeze, which is generally maintained at 70%. Even in the south, it is necessary to increase the concentration of antifreeze. Add one bottle at ordinary times and two bottles at this time, generally no more than 50%. In this way, no matter in Guangdong or driving to the icy north, you don't have to worry that the car won't catch fire.
In addition, experts remind that we should pay attention not to mix different brands and models of products, but also choose different regular brands of antifreeze according to the model. If we choose inferior antifreeze, it will not only raise the water temperature, but also corrode the engine. In addition, winter is the season of using warm air again. The warm air system will also fail after it has been out of use for a long time. Therefore, the owner's friends should first try whether there is hot air, whether the fan runs abnormally and whether the air duct is unobstructed. Sometimes, the antifreeze in the warm air water pipe does not flow for a long time, and the condensation blocks the circulating pipeline. Although it does not affect the driving, it is very troublesome to repair. After discovering these problems, we should deal with them in time.
Antifreeze third move
Pay attention to check the tires at any time. In winter, the rubber will harden and the friction coefficient will be reduced. Therefore, the tire pressure should not be too high, but not too low. The external temperature is low, the tire pressure is too low, and the serious soft tire can accelerate the aging, and aggravate the contact between the tire and the ground, which will accelerate the friction and reduce the service life of the tire.
In winter, we should often clean the inclusions in the tread, try to avoid using the tires that have been repaired more than once, and replace the tires with large wear, different brands and different patterns.
How to deal with the ice on the window countermeasure 1: if you want to remove the ice, you can start the engine first, turn on the warm air in the car, use the special ice and snow shovel for car glass, and slowly remove the ice from the ice crack. The correct way to wash the car is to start the car, turn on the heating system on the car, and then wipe the car with warm water.
The car's windshield may be damaged by the sudden change in the temperature of the hot water after the car is washed, which may also cause damage to the car's windshield. You can't wash the car directly with cold water, especially after the engine is heated up, the front temperature of the car is high, and washing with cold water will cause rapid cooling, which is very unfavorable to the surface paint.
Countermeasure 2: try to open the doors on both sides for ventilation after one day's use of the car. When the temperature in the car drops to about the same as that outside the car, turn on the power supply, brush the residual water on the windshield with a wiper, and then close the door and lock the car. You can drive on the road the next morning.
The reason why the glass freezes is that after people leave the car, there is still hot gas in the car. When the temperature in the car gradually decreases to the same level as that outside the car, the water vapor in the car begins to freeze.
