Ignition wire: Aging affects vehicle power and fuel consumption.

I believe everyone knows about spark plugs, and some car owners can replace spark plugs by themselves, but in comparison, ignition wires are rarely paid attention to. Some car owners wonder why there is no problem with a self-inflicted car, but they don't like to catch fire, fuel consumption becomes high, and the power is poor. If it is not caused by the rest, it is recommended that you check the ignition wire.

The two ends of the ignition wire are connected to the distributor and spark plug, respectively, and are the only way for the electric spark to be transmitted to the engine when the car is moving. Due to the high frequency of use, the working environment is harsh, and it is easy to age and damage, resulting in insufficient ignition energy and seriously affecting the power of the vehicle. Performance and fuel consumption.

It is recommended that the ignition wire be replaced every 20,000 kilometers for vehicles.

Brake discs: If there are obvious scratches, it is recommended to replace them.

I believe everyone is familiar with brake discs. At present, more and more vehicles are gradually transitioning from the braking configuration of the front disc and rear drum to the configuration of the front disc and rear disc. The advantage of using disc brakes is that the heat dissipates better and is easier to clean and replace.

Most car owners think that brake pads are more likely to wear out than brake discs and don't pay enough attention to brake discs. In fact, the forces between the discs are mutual, and the friction on contact produces wear. Brake pads that are smooth and susceptible to rough surfaces.

The brake pads themselves are wearing parts, but when we check and replace the brake pads, we should also pay attention to the condition of the surface of the brake disc. If there are obvious scratches, it is recommended to replace the brake disc with a new one to avoid unexpected consequences.

Wiper maintenance: Regular cleaning prolongs the life of the wiper.

There are not many opportunities to drive in rainy days, and there are fewer opportunities to use windshield wipers. As a result, some car owners don't pay much attention to the daily abnormal state of the wiper blades. When the wipers are affected, the problem is usually severe.

In addition to daily use, if there is less water on the front windshield bisimply leather, the air scraper of the wiper can easily increase the wear and tear of the wiper and affect its levelness. If there is something solid on the front windshield, such as dry droppings from birds such as pigeons, avoid using the wipers to scrape hard.

During use, the windshield leaves long, thin stripes on the wipers, making it difficult to see the outside world. This could be because of a foreign object on the wiper or a frayed edge. It is not advisable to rush to change the ** method. Clean the edges first and replace them if symptoms persist.

The exhaust pipe is one of the most vulnerable parts of the underbody, so don't forget to check for defects when you overhaul it. In particular, exhaust pipes with three-way catalytic converters should be carefully inspected.

1. The universal joint dust cover: Don't underestimate the dust cover outside the universal joint. Not only does it protect against dust, but it also prevents the loss of grease around the universal joint. Once the dust cover is damaged, the grease will disappear quickly. It will leak water, and the gimbal is prone to damage due to dry grinding.

2. To maintain the tire, first remove the stones and other inclusions in the tread pattern, and check whether the tire has bubbles, delamination, cracks, deformation, aging and other phenomena; Secondly, when disassembling and assembling tires, remove rust from the rims, check whether the inner tube and lining are damaged or wrinkled, inflate according to the specified pressure, and carry out tire flanging or transposition. Also, check whether the tires are rubbing against the wings, trunk floors, leaf springs, fenders, etc.

3. When checking the battery liquid level, if the liquid level is between the upper and lower lines, it is considered appropriate. At the same time, the difference in the level of each tank should be checked. If the liquid level is insufficient, you can unscrew the lid on the battery and pour distilled water to replenish the liquid level.

Check the terminals of the battery and use an iron brush to remove any dirt that has accumulated on the terminals. If the clamp is heavily dirty, sandpaper can be used to sand along the inner wall to remove the dirt.

4. Brake pads are usually based on whether the brake warning light on the dashboard is lit as the basis for judging whether to replace the brake pads, but this is the bottom line. If you change it at this time, it will already be quite dangerous. I would like to remind everyone that although all cars have this warning system, some directly sense the thickness of the brake pads, and some wait for the brake pads to be completely worn before turning on the warning lights and the brake fluid is greatly reduced and rising.

Clear the cong. If the latter is the case, the metal base of the brake pads and the brake disc are already in a state of iron grinding when the warning light is on. At this point, you'll see bright iron filings near the edge of the tires near the rim. Therefore, every time you enter the factory for maintenance, you must check whether the brake pads can be used, and replace the brake pads that are close to the end of their service life, rather than just believing in the warning lights.

Car repairs are usually judged by mileage and the service life of the oil. If it has reached 5000-7000, the oil filter needs to be changed within kilometers. Then, as the question is, if the mileage is not enough, does it need to be replaced.

If it is used very infrequently, it usually takes up to 6 months to replace. Otherwise, the oil will also reduce the effectiveness of protecting the engine. Or it is advisable to go out for a drive in addition to commuting.

Otherwise the car is a real pity.

Is motor oil more susceptible to spoilage when added to the engine? Since impurities such as old oil or sludge are still present in the small oil ducts, when new oil is added to the engine, it will mix with these impurities and accelerate the deterioration of the new oil. So, even if you don't drive for a year, the oil will fail due to long-term contamination with impurities.

When you start your car again, the failed oil loses its protection against the engine, which can damage oil-lubricated components such as valve, pistons, and cylinders. Do you think an engine overhaul is not worth the loss because it saves on repairs? Emphasize the role of oil again to attract your attention, oil provides lubrication, sealing, heat dissipation, rust prevention, cleaning and other functions for the engine, only the oil is in a healthy state to ensure the stability and long-term operation of the engine, good maintenance is the premise of healthy, stable and safe driving of the car.

When you buy a new car, 4S stores will give you a free first warranty, and some will give you a free first warranty. The 4S store requires you to come to the first insurance at 3000 kilometers or 5000 kilometers, otherwise it will be invalid. In fact, this time the first warranty was sent by the manufacturer, and it has nothing to do with 4S.

You can go to any 4S store of the same brand to do the first insurance. Some wear-resistant additives are wear-resistant additives to speed up the run-in of the engine and make it in the best condition. Therefore, I advise you to postpone the first insurance of a new car to 7500 km.

Motor oil has an expiration date. In a humid and temperature-friendly environment, a well-sealed oil has a shelf life of 3 years. After the engine is filled with oil, the working environment in which the oil runs is relatively complex.

When temperature and humidity are volatile, the shelf life of the oil is usually 1 year, so it is recommended to change the oil. The car is composed of many parts, even if the time has not arrived, it has been put aside for a long time, there is depreciation and wear, and it is also necessary to maintain it in time to prevent the aging of parts. If it is a new car, directly according to the instruction manual, the first two maintenance must be timely, because it is a new car, there are metal chips in it, and the oil must be replaced in time, otherwise the harm to the engine is quite great.

I think that when you take care of your car, you can specifically maintain the oil filter, air filter, fuel filter, and air conditioning filter. We must choose a better insurance company to inspect and maintain when we maintain, when there are accessories that need to be replaced, we must choose better quality accessories, try not to choose some three-no products or second-hand accessories.

The car oil needs to be replaced, and the tires should be replaced firstly by the oil of the car, then the tires should be maintained, and some consumable parts should be checked. The engine will form a thick carbon deposit when used for a long time, and the engine should be cleaned in time, and it is best to sterilize the connotation of the car on the maintenance wax, keep the car clean and tidy, and check the brake fluid in the car in time, and the chassis should be maintained for anti-rust.

Because the maintenance of personal conditions is not the same, there is about the maintenance of the engine, the maintenance is mainly to prevent or extend its life, as well as the maintenance of tires, the maintenance of the steering rod is necessary, according to their own situation to make the corresponding choice, a car interior maintenance, interior decoration, engine should be timely related maintenance treatment.

The specific places that should be maintained include the car's oil, spark plugs, brake pads, tires, and air conditioners; It should be noted that if there is an abnormal situation found during the maintenance process, it must be repaired in time.

<><1.Special precautions for car maintenance.

1).As one of the most important protection products for automobiles, the selection of high-quality lubricating oil can effectively protect the engine, reduce wear and tear, and make the vehicle have better performance.

2).Scientific and reasonable maintenance: The maintenance cycle of your car refers to the interval of car maintenance, mileage or time, license plate number, frame number, factory entry and exit time and other relevant information, remember to prevent settlement mistakes.

3).**If there are damaged parts of the spare parts, try to return to Qinhuai to prevent unscrupulous merchants from shoddy, bringing hidden dangers to the owner, and washing the car in rainy days is not only because the car is dirty, but more importantly, it is important to protect the car paint.

2.Key points for daily car maintenance.

1).Check the tires and their air pressure. If the car is driven for a long time, the tires will wear out, affecting the grip.

When driving on the highway, there will be a series of shock absorbers on the ground before entering the toll booth rest area, and when the car travels to the shock absorber, it must slow down, which will reduce the wear and tear of the tires. during normal driving; These are all aspects that novices need to pay attention to when they are on the road. Never help someone tow the car.

Always check that the oil, coolant, and battery electrolyte are adequate.

3.What details should be paid attention to in car maintenance.

1.Check the appearance before leaving the car. It is best to look around the car to see if the lighting is damaged, whether the body is tilted, whether there is oil leakage, water leakage, etc., and then check the appearance of the tire scale.

Doors, hoods, trunk lids, and glass condition check tires; Clean the inside of the car, clean the outside of the car to check for tire wear, and replace the tires when the trunk is close to tire wear marks. Avoid using carburetor cleaners. Most carburetor cleaners contain methylene chloride, aromatic compounds, and ethanol.
