After the car tour, you need to
Nowadays, car owners are growing stronger and stronger, and self-driving trips have become a popular leisure activity. However, how to ensure the safety of returning from driving, here are 7 must-do car inspections for you, from the body to the car system to the tires. All aspects must be checked to eliminate potential safety hazards!
1. Check whether the body paint surface and chassis are worn and scratched
First of all, go to a professional car wash to clean the body and chassis. Don't wipe it yourself. Because when the vehicle is driving at high speed, hard particles such as dust in the air will quickly scratch the surface of the vehicle and cause scratches.
After cleaning, check the paint, glass, and chassis for scratches or bumps, and decide whether to perform maintenance such as waxing and chassis armor, or contact insurance companies and repair shops for repairs.
A thorough and detailed inspection of the chassis is necessary as you inevitably pass through some complex and unpredictable roads on your road trip. For example, when a vehicle passes through some mountain roads, the chassis may be damaged by hitting some rocks.
It is also possible that the chassis may become dirty due to wading or muddy roads; and when passing through some sandstone roads, the salt contained in many sand grains will also erode the chassis. Cleaning and repairing the relevant parts of the chassis can ensure the durability of the chassis in the future, and it is also necessary to tighten the chassis screws.
2. Check whether the steering system is loose or short of oil
The steering system is related to the driving safety of the vehicle, so it also needs to be carefully tested. First check the oil quality and oil quantity of the steering system, and check whether there is any steering wheel shake or oil stains in the parking position of the vehicle during the post-holiday driving. If so, it needs to be repaired as soon as possible.
In addition, the severe vibration of the vehicle can also damage the steering system, and it is necessary to observe whether the ball head of the steering machine is loose.
3. Check whether there is any abnormality in lubricating oil, coolant and three filters
Engine oil, transmission oil, steering wheel oil and coolant are items that need to be checked in time after a vehicle has been driving at high speed for a long time. If the oil has been lower than the minimum scale marked on the oil dipstick, the same brand and model of oil should be added in time. If the color of the oil is no longer clear and becomes black and cloudy, it should be replaced immediately, and don't forget to replace the oil filter together.
If the engine experiences abnormal jitter, increased noise, increased fuel consumption, or poor acceleration, the oil circuit of the car should be cleaned as soon as possible, and the spark plug combustion should be checked. If there is any abnormality, it should be replaced in time.
4. Check the degree of wear of the braking system
When a high-speed road encounters an emergency, emergency braking is required, which is quite serious for the wear and tear of the braking system. When driving on rural dirt roads, if there are hard substances such as sand and gravel between the brake disc and the brake pad, it will also cause great wear and tear to the braking system when braking.
The maintenance of the brake system is mainly to check whether the brakes are abnormal and whether the response is sensitive. During high-speed driving, the wear of the brakes will be much worse than usual. If the sensitivity of the brakes is not enough, it needs to be adjusted in time. If the brake pads are worn excessively, they should be replaced.
There are also some situations to pay attention to, such as visually inspecting the surface of the brake disc through the aluminum alloy steel ring of the tire. If there are obvious grooves, it may be that some fine sand and gravel have entered between the brake disc and the fender when the vehicle is driving, causing the surface of the brake disc to be constantly rubbed and causing grooves to appear. In this case, the vehicle may make abnormal noises when walking, and these situations must be sent to a professional repair shop for repair.
5, check the car into the trend, electronic cooling fan and other foreign bodies
During the self-driving journey, there will be some leaves, plastic bags and insect carcasses and other debris entangled in the trend or intake grille, electronic cooling fan, etc. At the same time, the water tank and air conditioner condenser will also be covered with dust. If the vehicle passes through some poor roads or encounters flooding, the vehicle floor mat may be wet, moldy and produce peculiar smell. It is inevitable that a lot of dust will accumulate in the compartment, especially the suede wrapping parts such as the floor mat, roof and door veneer.
If conditions permit, the dust can be blown away with compressed air; when the engine is cooled, it can be washed into the trend or air inlet grille with water. If there is a lot of dust in the suede wrapping parts such as the floor mat, roof and door trim in the car, a professional steam cleaner is required for dry cleaning.
Although the dashboard and other parts are not easy to be stained with dust, the corners and corners should also be cleaned with a rag or cotton swab. If the carpet is wet, it should be dried in time and checked for moisture.
6. Check whether the suspension and tires need to be repaired
The inspection of the suspension is mainly to see if the shock absorber of the vehicle is in good condition, and if there is any oil leakage, it needs to be repaired.
The tire is the only part of the vehicle that makes contact with the ground, and its importance cannot be overstated. Long-distance high-speed driving will increase the temperature of the tire surface, and wear will also increase. First check whether the tire pressure of each wheel is within the normal range. If the tire pressure is too low, check whether there is a hard object puncture or a crack on the tire. Decide to repair or replace it according to the serious situation.
In addition, the tire pattern depth and wear uniformity should also be checked, and foreign objects such as stones included in the pattern should be removed. If the pattern depth is below the wear threshold, it should also be replaced in time.
7. Clean the trunk
During the Spring Festival, when visiting relatives and friends, a variety of gifts will be installed in the trunk. At the same time, various cleaning and maintenance agents, car mops, etc. will be piled up in the trunk, which will not only cause odor, but also chemicals such as cleaners will cause pollution to the surrounding environment.
Therefore, it is very necessary to clean the trunk after the holiday. When cleaning the trunk, it is necessary to use a professional cleaner to scrub thoroughly and wipe off the remaining detergent. Since the trunk is laid with velvet materials, which hide a lot of bacteria and dust, after cleaning the trunk, it is also sterilized with high temperature steam to remove bacteria and odors.
After cleaning, sort and organize the standing items. Glass rain remover, interior cleaner, photocatalyst, tire cleaning polish and other beauty maintenance products can be packed in a bag or finishing box to prevent the vehicle from being scattered everywhere. It is best to have a special bag for the car cleaning mop to avoid dust flying on the mop.
Finally, for cars, people can't put it down, and they usually take good care of them, but after driving back, the wear and tear of the car is worrying, and there are also many safety hazards. At this time, you should do a good self-inspection. These 7 items, dear, have you done it?
