Driving safety
After the National Day holiday, after go on road trip, car owners must do a good job of cleaning their cars after a long journey, especially maintaining the tires, chassis, engine oil and shock-absorbing suspension in all directions, so that they can "recharge their batteries" before going on the road.
Whole body "SPA"
In the second half of the National Day holiday, "cooling+rainfall" was ushered in many places across the country. On the way by car, the vehicle will inevitably be "invaded" by mud and rain. Therefore, it is necessary to thoroughly clean the car body first, so as to avoid residual dust, mud, etc. staying in the car body for a long time and damaging the paint surface.
In addition, the car should also be carefully cleaned. It is inevitable to "eat, drink and drink" to replenish energy in the car while driving. Snack residues such as biscuits and bread will also be inadvertently scattered in the corner of the car. Food residues should also be carefully cleaned to prevent bacteria from forming and mildew, thus polluting the air inside the car. Need to be reminded that it is necessary to focus on thoroughly cleaning the steering wheel, foot pads, seat gaps, air conditioners and other parts.
base
In the process of go on road trip, drivers are unfamiliar with the passing roads, so when driving on uneven roads, they should be alert to whether the chassis is slightly rubbed. If you hear abnormal noise, the driver should check whether there is any hard injury on the chassis guard after ensuring that the vehicle is parked in a safe place. If there is any hard injury, then check whether there is oil leakage and listen to whether the car is whining. If there is such a situation, you need to go to a repair shop or a 4S shop for further careful inspection. If there is no oil leakage and abnormal noise, it is necessary to go to the 4S shop for inspection after returning.
In fact, after the chassis of a car encounters a flat object, the brake hydraulic pipes, fuel pipes and other pipes hidden in the grooves of the chassis steel plate are unlikely to be damaged. However, if you hit a sharp object such as a raised stone on the ground, you should pay special attention to whether it will cause damage to the pipeline behind the chassis.
Tire and brake system
Go on road trip often passes through places with complicated road conditions, especially those with uneven ground and lots of gravel, which have a certain impact on the tires. Therefore, when returning from driving, we should check the tires one by one to see if there are any cracks and scratches, and monitor whether the tire pressure is normal. In addition, it is best to clean the hidden gravel in the tires in time, but don’t dig with the car key to avoid hurting the tires. It is best to use professional tools or moderate knocking to remove the gravel in the tire gap.
In the process of go on road trip, it is inevitable that there will be frequent braking due to long downhill or other complicated sections, especially on the gravel pavement, and the broken gravel on the road will increase the wear of the brakes. Therefore, check the brake system. When it is found that the thickness of brake pad (disc) or brake shoe (drum) is close to or less than the minimum thickness specified by the manufacturer, it should be replaced immediately. In addition, if dents appear on the contact surface of the brake pad or brake shoe, they should be polished in time to ensure the contact area with the brake pad and improve the braking force.
Oil, liquid and filtration
Go on road trip should check the oil, filter and liquid before and after returning. Oil mainly includes engine oil, gearbox oil, steering wheel oil, brake oil, etc. Liquid mainly refers to coolant, brake fluid, glass liquid, etc. These are all items that need to be checked in time after the vehicle has been driving at high speed for a long time.
If the engine oil is lower than the minimum scale marked on the oil dipstick, the engine oil of the same brand and model should be added in time. If the color of the oil becomes turbid, it should be replaced immediately and the oil filter should be replaced at the same time. It should be noted that the brake oil will fail after a long time because it absorbs the moisture in the air. To replace the brake oil regularly, it is best to replace it once a year.
In addition, we should also do a good job in the inspection of automobile air conditioning filter elements and air filter elements. Because the air conditioning filter and air filter are easy to absorb more dust after running a long distance, it may cause poor engine work, excessive oil consumption and damage to the engine. If less dust and light blockage are found, high-pressure air can be used to blow it clean from the inside out and continue to use it. Dirty air filters should be replaced in time.
Damping suspension
After go on road trip, we should pay attention to whether the suspension parts need to be repaired. In fact, after the vehicle has been driving for a period of time, the suspension will have certain wear and tear. So how to judge whether the suspension is damaged? The Beijing News reporter combed the information and learned that if you feel very bumpy and shaky when driving, especially on the bumpy road, there will be a rolling sound, which may be a problem with the suspension.
If the vehicle deviates when turning, it may also be a problem with the suspension components. Different suspension components will affect the steering response, tire steering angle and vehicle balance center, which will make the vehicle cumbersome or difficult to steer.
In addition, stop quickly in a safe area and pay attention to the front of the car. If the front of the car will rush down, there will be problems with the front shock absorber or the rear shock absorber, which makes it difficult for the suspension to keep the car balanced under emergency braking. In addition, if you hear a dull metallic sound from the front of the vehicle, it means that there is something wrong with the control arm or the subframe bushing.
