What projects do you need to do in the spring of the car?

1.Replace the antifreeze. According to the type of antifreeze specified by the manufacturer, it is filled into the engine. The engine cooling system should be cleaned before refilling with antifreeze. The use of long-lasting antifreeze throughout the year ensures that the engine is well cooled.

2.Check the clean fuel system. The fuel system should be thoroughly cleaned before winter, and it is difficult to troubleshoot the fuel system in the cold winter.

During seasonal maintenance, all filters should be thoroughly cleaned, the fuel filter element should be cleaned or replaced, and the sewage from the oil-water separator should be discharged and cleaned to eliminate the hidden danger of possible failure.

3.Change the lubricating oil. If the car uses single-grade oil (only suitable for summer or winter), the lubricating oil must be replaced to meet the seasonal temperature requirements during seasonal maintenance; If you are using a multi-grade oil that is suitable for winter and summer, you only need to change the lubricating oil according to the mileage between oil changes.

Multi-grade lubricating oil (engine oil, gear oil, etc.) has many advantages such as large adaptation range, fuel saving, and cost saving.

4.Maintain the battery. Before winter, the battery should be cleaned and supplemented with distilled water, the density of the electrolyte should be adjusted, and the charger should be used to charge it to ensure that the battery is in good condition.

5.Inspect, clean and tighten the relevant parts. For example, clean the outside of the water tank, eliminate ventilation obstructions, check and adjust the status of the fan belt, check whether the thermostat is working well, take appropriate insulation measures for the engine radiator before winter, the tire pattern on the ice and snow road should not be too shallow, and try to use non-skid tires.

6.Protects the body. Use waxing or sealing glaze to prevent the paint surface from fading and aging.

Attention should be paid to paint corrosion.

There are many mosquitoes in spring, so when the car is driving at high speed, the body is easy to stick to the flying insects that hit it. The acids in flying insects can damage the paint surface of the car, so you should develop the habit of washing and waxing the car after traveling. There is also a lot of rain and wind and sand in spring, so you should pay special attention when washing and wiping the car, do not let the fine sand and gravel scratch the car surface, and do not let acid rain stay on the car surface to corrode the paint surface.

The interior of the car is humid and anti-bacterial.

The humid air in spring is prone to the growth of bacteria, so it is necessary to disinfect the interior of the car. First of all, we must pay special attention to the anti-bacterial work in the car room, and secondly, we must keep the car room dry and hygienic, especially for the car cushion, air outlet, these sanitary dead corners should be cleaned to keep the car environment dry and tidy.

The oil should be changed in the spring.

When it comes to changing seasons, it is necessary to pay attention to the replacement of accessories that are only suitable for different seasons. When spring comes, it is necessary to replace the winter lubricating oil (or lubricating oil in low temperature areas) in the engine, transmission, steering machine, rear axle, etc. in time. If the viscosity of the oil you are using is too high, you should also change it in time or change it to a summer oil later.

The water tank needs to be cleaned for winter.

After a winter, the car should also clean the water tank, if not cleaned in time, it is easy to turn on the air conditioner when the water temperature is too high, resulting in the phenomenon of the water tank boiling.
