Must read for long-distance driving! These parts must be checked before traveling!


What parts should be checked for long-distance driving? Because of the longer distance and driving time of long-distance driving, some parts of the car will be subjected to more severe tests than daily driving. Therefore, before traveling, we should properly check the car and make preparations to reduce the occurrence of accidents during driving. Before driving for a long distance, we should focus on checking these car parts.

tyre

Due to the long mileage of long-distance driving, the first thing to check is the tyres, which is the same as choosing a pair of comfortable shoes for hiking. Some small conditions of the tyres may cause a tyre blowout, which directly affects driving safety. The following aspects are the key points to check the tyres:

1. Tire pressure.

Adjust the tire pressure value according to the recommended tire pressure value in the automobile manual. The influence of temperature must be taken into account here. The recommended tire pressure in summer and winter is different. In winter, the standard tire pressure of the automobile should be appropriately adjusted by about 0.2 bar. According to the lower limit of the standard tire pressure in summer; In addition, it is necessary to consider the road conditions of the travel destination. If the road conditions are poor and bumpy, appropriately lower the pressure of the tire by 0.1-0.2bar; At the same time, how to travel with full load is recommended to be set according to the recommended standard upper limit of vehicle tire pressure. For long-distance travel, the old driver suggested that the tire pressure should be appropriately increased by 0.1-0.2 bar.

2. Tyre condition

Before traveling, you need to check the wear of the tire. For example, if the tire has a small hole punctured by a nail, it will not affect long-distance travel, but if it is similar to the following wound, you must replace the tire to prevent accidents.

In addition, many people ask whether the tyres can be used at high speed if they have patches. If it is a patch, it is not recommended to use high speed because this method is not durable and safe. When the tire is seriously heated or bumped, it is easy to burst. If it is an internal patch, it can barely cope with long-distance driving two times at a time, but if there are more than two patches, it is recommended to change the tire before long-distance driving.

Automotive related fluids

The oil part is a little simpler than the tire part. Remember to check the "five oils and two fluids" - engine oil, gasoline, transmission oil, brake oil, steering oil (steering oil is not required for vehicles with electronic steering system), glass water and coolant. The oil level and service condition (whether it is black and has many fine particles) are the main factors to check the oil. For transmission oil, you can check the vehicle maintenance manual, If the current mileage of your car plus the mileage to be driven for the next long-distance trip just exceeds the recommended mileage of the gearbox, it is recommended to replace it in advance; There is no need to worry too much about the brake oil. Just like the transmission oil, look at the maintenance mileage, and replace it in advance if it is near. As for the steering oil, since most of the current cars are electronic steering, there is no need to check the steering oil, but if it is an old mechanical steering car, you can check the steering oil at the store.

Other parts

Finally, we suggest to check the brake pads and the on-board tools. The brake pads mainly depend on the degree of wear, and they should be replaced in time according to the degree of wear. The on-board tools mainly check whether the lower tools are complete, whether the air pressure of the spare tire is sufficient, and whether the spare tire is aging. The most important thing is to maintain the driver's physical and mental health. After all, the quality and stability of the car are good now. The probability of the driver's problems is much greater than that of the car.
