As the Chinese economy continues to take off, cars are now a popular tool for people to travel. However, the complexity of some roads in China will inevitably lead to injuries in private cars. There is a saying that is very much about "people rely on clothes," the same car's appearance is also very important. Below, car maintenance experts will teach the owners how to repair body scratches and cure the chassis.
1. In addition to scratches on the body of the vehicle, because the owner is not familiar with the road surface or some road conditions are poor, it may lead to obvious scratches and bumps on the outside of the vehicle, especially in the front bumper position. Therefore, there are a large number of owners who perform paint painting on the outside of the vehicle. However, according to professionals from the auto repair company, some cracks caused by the impact of the paint layer are not large, and therefore it is generally believed that it does not affect the aesthetics of the vehicle, and it ignores it. In fact, the metal under the paint has begun to rust. When the owner can observe from the outside, the internal metal layer has been rusted very badly.
2. Chassis healing Some vehicles scratched the chassis during self-driving, but they are often overlooked during maintenance. According to professionals, if there is any abnormal sound in the chassis, the steering wheel is shaken, or the vehicle is in a parking position, it indicates that the chassis has been damaged. This is because after the road surface scratches the chassis, it may cause some parts of the chassis to be deformed. In particular, the upper and lower swing arms and the left and right direction tie bars are easily deformed. In addition, even slight scratches can cause minor leaks in the oil sump or in the transmission oil sump, etc. These are problems that the owner himself cannot detect in time. Therefore, the owner is better to do a professional chassis anti-rust care or spray paint to do a chassis armor 3. Brake to be sensitive to driving a long time car, brake system is prone to problems. In some car repair shops, a long queue of vehicles came to check the brake system. One is to observe whether the surface of the brake disc is smooth, if there are obvious grooves, this is because when the vehicle is driving on the gravel road, some small sandstones are stuck between the brake disc and the mudguard, constantly rubbing the surface of the brake disc. As a result, if the situation is serious, it will significantly affect the brake performance. At this time, it must be opened to the designated service station to check if it is necessary to replace the brake pads. If you find that the brake fluid level drops, check the brake fluid immediately for leaks. Before checking the brakes, carefully clean the dirt on the main tank to prevent dirt from falling into the tank. For uncalibrated cylinders, keep the liquid level 6 mm from the top of the cylinder. If there is a scale, just keep the liquid level higher than the scale. Professionals remind the owner of the vehicle and understand some conservation knowledge. If maintenance is done in some street shops, maintenance personnel should always be reminded of maintenance items.
4. The tire pressure is guaranteed to be in the normal driving condition. Because the tyre is in contact with the ground for the longest time and the wear is the most severe, it is the place that needs to be checked. If the tire is a radial tire, the tire wall is the weakest part of it. Because the entire radial tire has only steel wire on the sidewall, it must be used with great care. If you travel at a high speed in a bad road condition during a trip, the tire may hit a deep pit or other foreign object, which can cause severe tire deformation between the impact object and the rim flange, causing the tire cord fabric to break. The air inside the tire will rise from the broken yarn to form a bulge. If you find that the tire bulging should be replaced in time, it is very easy to cause a puncture when driving at high speed. Measure the tire pressure to see if it is within the normal range. If it is abnormal, adjust it in time.
5. Is the engine oil sufficient to ensure that the engine is working properly? Therefore, if you return by car, you must check if the engine oil is sufficient. The step is to pull off the oil dipstick first and wipe it clean with a cloth; then reinsert the dipstick – try to insert it in the end, otherwise the reading will be inaccurate; then pull the dipstick again, Check the oil level at the end of the dipstick. If the oil level is lower or slightly higher than the low oil level, remove the oil filler cap and fill the oil. The amount of oil that needs to be filled with the oil level is between the low oil level line and the high oil level line on the dipstick. After adding, pay attention to tighten the oil cover.
6. The liquid level of the coolant needs to meet the standard state of cooling the engine. Check the transparent coolant box. If the liquid level is kept between the "F" and "L" marking lines of the reservoir, it will meet the requirements. If the liquid level is at or below the "L" line, the coolant must be filled so that the liquid level reaches "F" line. After the coolant is filled, if the coolant level drops in a short period of time, there may be a leak. Visual inspection of radiators, hoses, engine coolant filler caps, radiators and drain cocks, and pumps are required to see if there is any water flow. If no leak is found, the car must be taken to a designated service station for further testing. It should be noted that to prevent burns, do not remove the radiator cap when the engine is still hot.
7. After the battery has been treated for a long distance, the battery of the car may be strongly shaken and the battery may splash out. At this time, check the external battery for corrosion or loose joints, cracks or slack in the presser. If the battery is corroded by the spilled battery fluid, it must be cleaned with a mixture of warm water and baking soda, and the outside of the joint is greased to prevent further corrosion. If the connector is loose, tighten the nut of the clip, but do not tighten it too tightly. Tighten it so that the battery can be held in place. Too tight will damage the battery case.
8. In addition to dust and dust on the drive, the carriages are traveling in a completely unfamiliar environment. Therefore, the owners like to roll down the window to observe the scenery outside the car. However, due to the long opening time of the windows, a lot of dust accumulates in the carriages. Especially in carpeted areas such as carpets, roofs and door trims, it is difficult to dispose of dust. This requires a professional steam cleaner to dry clean these parts. Other parts of the compartment, such as the instrument panel, are not easily contaminated with dust, but they should also be cleaned with rags or swabs to prevent dust accumulation.
9. Air conditioning refrigerant leak detection Air conditioning maintenance is divided into two aspects, one is to carefully check whether the air conditioning refrigerant storage tank located at the front of the vehicle has leaked due to bumps or bumps after returning from the journey. If the leak must be filled as soon as possible and the refrigerant is filled. The second case is due to the harsh environment during the journey caused by large amounts of dust in air-conditioning radiators and pipes. As for dust accumulation in the air-conditioning pipeline, although it cannot be directly contacted, it is possible to use a method of directly injecting a special cleaning agent into the air-conditioning air inlet and then opening the air-conditioning inner circulation to remove the accumulated dust in the pipeline. This cleaning agent is not corrosive. There is no need to worry about damaging the pipe plastic components.
10. Is there any maintenance for glass besides oiled glass that can be cleaned with water? Yes, glass maintenance is very knowledgeable, not all problems can be solved with fresh water. For example, if the glass is not visible to the naked eye after it is oiled, the wiper wiper performance will be greatly reduced. At this time, you must remove the grease with a grease remover.
Tire valve is a self-contained valve which opens to admit air to inflate a tire, and is then automatically closed and kept sealed by the pressure in the tire, to prevent the air from escaping. Tire valve stems are made of aluminium, steel or black rubber. It includes tubeless tire valve and tube valves for passenger cars, truck, buses, tractor and ATV etc.
