Measuring tire pressure
Tires have measured every inch of their journey with their own bodies, which makes them particularly hard. Therefore, the tire pressure should be measured first and the same tire pressure should be maintained for four rounds. If there is an abnormally low tire pressure, you must carefully observe whether the tire has been punctured, and if necessary, repair it in time. If the wound is too large or the wound appears on the sidewall, it can only be retired.
There is also the problem of tire balancing. Poor pavement in the wild is likely to affect the balance of the tires. The originally smooth car suddenly appeared as if it was a tantrum, and abnormal tremor appeared. This indicated that the balance of the tire was invalid. This may be due to deformation of the hub, wear of the tires, or in the event of a strong bump, which will cause the balance weights clamped on the hub to be lost. Therefore, it is necessary to rebalance each tire.
Change oil
During driving, high-load operation will put the engine under test, so it is necessary to check the engine oil and tank water. If it is an automatic transmission, check whether the transmission oil is missing, and if it is over-consumed, make up for it in time.
If the travel distance is relatively long, it is better to change the engine oil, because the high temperature work of the engine may deteriorate the engine oil. It is also necessary to pay attention to whether the engine belt is loose or not. In addition, the dusty passengers on the road may fill engine blocks, engine radiators, and air-conditioning radiators with mud, affecting the engine cooling and air-conditioning work. At this time, they need to go to professional dealers and use special cleaning agents for engines and radiators. Special cleaning.
Do 4 rounds of positioning
The bumps along the way bring a constant impact to the chassis, and the 4 wheel alignment of the vehicle may change accordingly, resulting in abnormal wear of the tire. Therefore, after returning from the journey, the chassis of the vehicle should also be checked. If necessary, a four-wheel alignment should be made for the car. In the same way, severe vibrations can damage the steering system and should be observed for loosening of the steering ball. In addition, the screws in the chassis section should be tightened.
Check the brake system
The braking system is also an inspection section that cannot be ignored. Frequent braking and gravel-laden environments during the journey can severely wear out the brakes. If the brake wears excessively, or if there is a "click" noise when the brakes are applied, it means that the brakes need to be checked.
Clean engine oil circuit
There is a certain difference in the quality of oil products in various regions, and even some oil products are unqualified, and the addition of such oil products has great damage to engines and oil lines. If a poor quality gasoline is used, on the one hand, the engine will produce knocking and noise. On the other hand, the three-way catalytic converter will easily fail. At this time, the engine will often show weakness and increase fuel consumption, which will seriously damage the internal parts of the engine. If the above situation occurs, it is best to put the oil off after the service station, and then add some additives to clean up the oil road for maintenance.
