How to see if the engine is healthy?

The weather gradually turned cold, and car maintenance entered a "hot period". In winter, cars are prone to problems such as increased fuel consumption and difficulty in striking a fire. It is necessary for car owners to conduct a comprehensive and systematic inspection of their cars. So, where should we pay special attention?

1. Machine lubricating oil

The engine is called the "heart" of the car, and the lubricating oil is closely related to the health of the engine. The state of engine oil is affected by the change of temperature, and car owners are used to changing engine oil in advance in cold weather. However, in fact, the temperature in the south will not be too low most of the time, so there is no need to change it in a hurry. If it's too much trouble, you can choose four seasons general engine oil. For some extremely cold areas in the north, for the normal operation of the engine, it is necessary to replace the lubricating oil with low viscosity to enhance the fluidity. Therefore, everyone should open the oil cap regularly according to the temperature, observe the color and viscosity, and then decide whether to replace it. At the same time, don't forget to measure the oil quantity with the dipstick.

2. Tires

The traction balance performance of tires in rain and snow weather is very important, and the tires on ice and snow roads should be safe in winter. Based on the above requirements, the owner should carry out three inspections on the tires. First, check the damage. Check the tread depth of the tire, whether there is air leakage, whether there are scratches, and whether there are foreign bodies in the tread seam to confirm the friction and integrity of the tire. Second, tire pressure inspection. In winter, when the temperature is relatively low, check whether the tires are transposed. In case of running deviation or abnormal bumps, four-wheel alignment should be carried out in time. Warm reminder, due to the extensive use of front tires, you should be more careful when checking.

3. Antifreeze and glass water

Antifreeze mainly plays a cooling role. In an emergency, some riders will use water instead. But don't forget to replace it when the temperature is low, otherwise the water will freeze and expand, damaging the cooling system. At the same time, antifreeze also has the functions of scale prevention and rust prevention. If the antifreeze is deteriorated or insufficient, it will seriously affect the heat conduction and cause the engine to burn out at high temperature. Therefore, it is necessary to check, replace or supplement the antifreeze that meets the freezing point in time. There is also glass water, which is used as a cleaning solution for the windshield of the car. Check if it freezes. If it freezes, please don't use the water spray function first, and then operate after the engine temperature thaws.

4. Heating system

It is natural to check the performance of the whole heating system when heating in cold weather. If the coolant pipe is blocked and there is scale in the water tank, it will affect the heating effect, so it is necessary to focus on cleaning both. In addition, check whether the windshield, heat exchanger and air outlet are in good condition. Remember to clean or replace the filter element after the wet summer to prevent dust and bacteria from affecting your health.

5. Headlights

Winter came on its own initiative, and it got dark earlier and earlier. It is also prone to foggy weather and low visibility. More need to use lighting. This requires checking turn signals, tail lights, fog lights, etc. Can work normally. Be alert when the brightness of the headlights is not enough, and check the aging of the headlights. Find that the lights are foggy, damaged and the hood is not clean, and deal with it as soon as possible.

6. Chassis

This part is easily overlooked by everyone, but the protective layer of the chassis is weak at this time and it is easy to rust. Over time, the oil leakage under the car will be very serious. Therefore, the chassis is cleaned to remove the sediment, rust and other sundries attached to the bottom of the car. You also need to protect the chassis, such as armored.
