Daily car maintenance knowledge
We all know that the good work of a car cannot be separated from the care and maintenance of the car, so daily maintenance is indispensable. Therefore, it is extremely important to do daily car maintenance. So how can you do daily car maintenance and what should you pay attention to when maintaining a car? Let’s take a look at the following daily car maintenance knowledge that I have compiled.
First: Speaking of car gear shifting: Many people will accelerate in 1st gear after starting the car, which will damage the engine. I think the speeding up gear should be 3-4 gears, 1-2 is a starting point. Excessive gears, if the speed is increased by 1-2, the general speed is between 2500-3500. If the gear does not match the engine speed, it will cause serious damage to the engine. It may burn engine oil over time. In severe cases, 3 guarantees. In serious cases, I think I need to replace the engine assembly.
Second: Regarding the issue of engine oil, I think semi-synthetic oil can satisfy the lubrication effect of the car. Why do you need to eat refined oil? Is it really too much money to spend? Engine oil has a lubrication function. Don't let all parts dry grind. Just insist on changing it at 5,000. It is recommended to use good engine oil, but it does not mean that you must use fully synthetic oil.
Third: Air filter, I think this little thing is a very delicate thing. Although some people see that it is not very dirty after 5,000 kilometers, they can just blow it with high-pressure air, but From my personal point of view, I think it is better to replace it with a new one, because the intake approach is a very important link. It is said in Zao that gasoline engines enter the cylinder and burn the mixture before it is burned. The crankshaft drives the transmission system, and the car When you start walking, the air intake system is also an important link. Clean the air intake system when you park your car and insist on replacing the air filter with a new one every 5,000.
Fourth: Replace the gasoline filter element every 20,000 kilometers, and insist on doing it. There are many unscrupulous gas stations now, and there are many local oil refineries in northern Shaanxi. It is estimated that it will be sold to gas stations all over the country. It's worth replacing it. The gear oil of the transmission is also changed every 20,000 yuan. Although there are oil seals and sealing strips, it is impossible to keep speeding all the time. It is close to the bottom of the chassis. When passing by, it will inevitably get dirt and dust. If a vacuum can be achieved, then it will not It’s necessary. It seems that there is no vacuum transmission yet. It’s better to change everything. The shifting is simple, and the stability of the speed of the 8-shaped wheel is directly related to lubrication, so as to avoid breaking the 8-shaped wheel and spending a lot of money. All models are the same, and the maintenance cost of the automatic transmission is higher. In fact, long-term bumps in the car will cause the pins that go through the splayed wheels to fall off. You really have to worry about it when passing through pits. I have suffered from it. One pin fell off and I had to replace it directly. The outer casing is not cost-effective, and even worse, it can ask you to replace the splayed wheel.
Fifth: The circuit is also very important. Check the fuses and relays and keep them clean. Keep the equipment contacts in good condition. Check the wire buckles to avoid spontaneous combustion in hot weather. It is not necessary to replace the spark plugs if they have carbon deposits and spontaneous combustion. If you go to 4S, you can change it yourself. Understanding the structure of your car will ensure the smoothness of your future travels. When replacing the gasoline filter element, clean the fuel injector. Good fuel injection effect will lead to fuel saving.
Sixth: Just keep the tire pressure to 2.2. If it is too hard, it will damage the tire. If it is too soft, it will cause poor transmission and waste oil.
When it comes to car maintenance, there are really many things. The last thing is to insist on driving during the running-in period. If you persist, the maintenance cost will be reduced to very low. Of course, don’t just go to 4S if you have nothing to do. Of course, you will definitely go to repair the car if it causes an accident. Others There is no reason not to go there if you have to pay for it. You can go to a general repair shop to change the oil or filter. Those with strong financial strength can go to 4S. Treat the car like a child. This is what the party and the masses said. It is indeed true. Treat it like a child. As long as you use your heart, it will bring us a lot of happiness. At least it will not leave you on the roadside. You can do anything by yourself. Move your hands.

Car maintenance cycle
1. Main maintenance items should be checked and maintained after the car is collected
Check and replenish fuel and lubricants. Clean the interior and exterior of the vehicle as well as the engine and chassis.
In severe winter, if antifreeze is not added to the cooling system, the radiator cover, drain switch, and engine drain switch should be opened, drain the cooling water, and start the engine for a short time. Drain the water to avoid remaining frozen cylinders, radiators, and vehicles with air brakes. The sewage in the air tank should be drained. After turning off the engine, close the switch and tighten the handbrake, and check the ammeter for leakage (the pointer points to the "-" side).
Check the horn, lights, and wipers. Check whether the leaf spring is broken and whether the spring lifting lugs and riding bolts are loose. Check the half shaft and tire nut to see if the steel ring is damaged or cracked. Check the tires for cracks and deflation.
2. First-level vehicle maintenance items
After the first-level maintenance work is completed, the vehicle should be clean and tidy, the connections should be firm, the three filters should be smooth, and there should be no oil, water, or leakage. Gas, no leakage.
The cleaning operations of the first-level vehicle maintenance include: cleaning the body and wiping the engine and chassis parts. Clean and maintain the air filter. Clean the fuel filter. Release the sediment in the oil filter, turn the filter handle 3-4 turns, clean the oil filter, and replace the filter element according to the degree of contamination. Drain the oil and water accumulation from the air reservoir.
3. Vehicle first-level maintenance and lubrication work items
Check the oil levels of the engine, transmission, rear axle, and steering gear, and add lubricating oil according to regulations. The oil nozzles of all parts of the vehicle are fully equipped and effective, and grease is added according to regulations (water pump, rotating shaft, universal joint, steering knuckle, steering tie rod, etc.).
IV. Vehicle first-level maintenance inspection and fastening work items
Check the steering gear, tie rods, straight tie rods, and the tightness of each steering arm connection. Check and adjust the tightness and fixation of air compressor, engine and fan belts. Check the brake valve and brake pipe for air leakage, check the brake fluid level of the hydraulic brake master cylinder, and add brake fluid according to regulations. Check and adjust the clutch pedal, the free travel of the brake pedal, and check whether the brake pedal fixed shaft and cotter pin are intact and reliable. Check and tighten the connections and bolts of all parts of the vehicle. Check tire pressure and inspect tires for damage. Check the battery shell, clear the vent hole of the small cover, and replenish the electrolyte. Check whether the lights, wiring, and wiper switches are complete and intact. Whether the speaker volume and tone are normal and whether the various instruments work well.
There are many types of regular maintenance items, and the items maintained by each car manufacturer are generally the same.
Among the regular maintenance items, there are many items that are not easily damaged under normal driving conditions, so they only need to be checked, such as: tire side slip, braking effect and pedal play, hand movement, etc. Braking effect, clutch clearance and clutch oil volume, steering wheel clearance, air conditioning system, instrument functions, seat belts and warning systems, electric windows, sunroof, rearview mirrors, lights, wipers, horn, antenna, central control lock, battery Liquid and air-conditioning compressor belts, distributor covers and flame distributors, high-voltage wires, ignition timing, idle speed and exhaust gas, power steering system, gasoline pipes, drive shaft dust boots, exhaust pipe mufflers, suspension fixing nuts ( Chassis inspection), tires and wheel discs, wheel bearings, front brake pad pump oil pipes, deceleration secondary air intake system, positive crankcase ventilation system, evaporative exhaust gas control system, intake air temperature control system, coal contact converter and Oxygen sensors, etc. If the above equipment is damaged (abnormal) after inspection, the maintenance factory will replace or adjust it.
When a new car travels 1,000 kilometers, it is necessary to replace the engine oil, oil filter and transmission oil. Because all the parts of the new car are completely new combinations, they cannot be completely smooth and tight when in contact with each other. For example, the friction between the piston and the piston ring, and between the gears in the gearbox will produce fine residues after friction, and these residues will flow into the engine oil and gearbox oil that lubricate the parts.
Spark plugs are replaced approximately every 20,000 kilometers, and some car manufacturers replace them every 30,000 kilometers.
Some items only need to be lubricated when the mileage (or time) is reached, such as: door buckles, throttles and electric pile heads; and the rear brake pad pump oil pipe is 15,000 Cleaning is carried out every 10,000 kilometers, and then cleaned every 10,000 kilometers; in addition, the valve clearance is adjusted every 20,000 kilometers. Some oils and parts need to be replaced as soon as the mileage (or time) is up. For example, the engine oil needs to be replaced at the 1,000 kilometers, and then every 5,000 kilometers; the oil filter also needs to be replaced. Replace it once every 1,000 kilometers, and then every 10,000 kilometers; replace the transmission oil once every 1,000 kilometers, and then every 20,000 kilometers; the water tank coolant must be checked during every scheduled maintenance. But it needs to be replaced every 20,000 kilometers; the air filter should be replaced every 20,000 kilometers (the maintenance shop will clean it for you every 5,000 kilometers); the gasoline filter should be replaced every 20,000 kilometers; and the spark plug should be replaced every 10,000 kilometers. The maintenance shop will inspect it once and replace it every 30,000 kilometers; brake oil should be replaced every 40,000 kilometers; the generator belt and power steering pump belt should be replaced every 50,000 kilometers; and the timing belt should be replaced every 70,000 kilometers.
Blind spots in car maintenance
1. Ignition wire: Aging will affect vehicle power and fuel consumption
I believe everyone knows about spark plugs, and some car owners can do it themselves. Replace the spark plugs, but in comparison, the ignition wires receive less attention. Some car owners are wondering why there is nothing wrong with their car, but it just doesn't catch fire, has high fuel consumption, and has poor power. If it is not caused by other reasons, it is recommended that you check the ignition wire. Both ends of the ignition wire are connected to the distributor and spark plug, which is the only path for electric spark to be transmitted to the engine when the car is running. Due to the high frequency of use and the harsh working environment, it is prone to aging, damage, etc., resulting in insufficient ignition energy and seriously affecting the vehicle power. performance and fuel consumption. It is recommended that the vehicle's ignition wire be replaced every 20,000 kilometers.
2. Brake disc: If there are clear scratches, it is recommended to replace the brake disc with a new one.
I believe everyone is familiar with brake discs. Currently, more and more vehicles are gradually Transition from the braking configuration of front disc and rear drum to the configuration of front disc and rear disc. The advantage of using disc brakes is that they have better heat dissipation and are easier to clean and replace. Most car owners think that brake pads are easier to wear than brake discs, and they do not pay enough attention to the brake discs. In fact, the forces between the discs and the discs are mutual, and the contact friction will cause wear, and the surface of the brake disc is larger than the brake pads. Smooth and easily affected by the rough surface of the brake pads.
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 brake disc surface. If clear scratches appear, it is recommended to replace the brake disc with a new one to avoid unexpected consequences.
3. Wiper maintenance: regular cleaning to extend the life of the wiper blades
There are not many opportunities to drive in rainy days, and the opportunities to use the wipers are relatively few. Therefore, some car owners have concerns about the daily use of wiper blades. The abnormal state is not taken seriously until it affects the wiper effect, and the problem is usually serious. In addition to daily use, if there is little water on the front windshield, wiping the wiper dry will easily aggravate the wear of the wiper and affect its levelness. When there are solid objects on the front windshield, such as dried feces of pigeons and other birds, avoid using the wiper directly to scrape. Since the material of the wiper blade is mainly rubber, it will age and harden over time. Car owners can buy a rubber curing agent from an auto supply store and spray it on the rubber part of the wiper blade every month to protect the rubber strip. , which can extend the service life of the rubber strip by at least 30%-50%. In addition, when you find that the wiper is not wiping completely, you can also buy a wiper blade repairer, which rubs the rubber part of the wiper blade to repair the irregularly worn parts.
If during use, you see that the wiper has left long and thin streaks on the windshield, making it difficult to see the outside world clearly, this may be because there is foreign matter on the wiper or the edges are worn. , the treatment method should not be in a hurry to replace it. First, clean the edges. If the symptoms are not eliminated, it needs to be replaced.
