Theoretical fuel consumption: 6.9 liters / 100 kilometers Le Feng normal maintenance air conditioning Le Feng cooling is still very fast, but this air conditioning used in the 1.4L car, a little too much. After turning on the air conditioner, the power drops significantly, if no other adjustments have been made, after turning on the air conditioner, the second and third gears become much softer, and the noise becomes louder when you step on the gas pedal heavily, but the acceleration is quite weak. If you encounter this problem, no need to be too nervous, you need to go to the automobile repair service station to communicate with the maintenance personnel to adjust the maintenance. Extraordinary attention: the extraordinary attention of the drive belt repair Do not repair the drive belt, repair will lead to drive belt material breakage, resulting in damage to the drive belt. Check all belts for cracking, blooming, wear and proper tension, adjust or replace belts if necessary. Special Considerations for Steering Wheel in Forward Position and Steering Column Locked Before disconnecting the steering column or intermediate shaft from the steering gear, the wheels must be held in the forward position and the steering column must be in the "Lock" position or the coil assembly in the steering column will be misaligned, resulting in damage to the coil assembly. Modifications to the engine or its components affect the vehicle's emission control and may cause the Malfunction Indicator Light (MIL) to illuminate. Modifications may also prevent the vehicle from passing required emissions inspection/maintenance tests. ABOUT CARPET REPLACEMENT To avoid personal injury and vehicle damage, when repairing or replacing the carpet, use carpet of the same thickness and material size as the originally installed carpet and return the carpet to its original position. Operation of the engine compartment cover latch When opening the engine compartment cover, observe the operation of the auxiliary latch, which should prevent the engine compartment cover, from opening completely when the main latch is released and the auxiliary latch is released. The engine compartment cover must be able to close tightly. SPARK PLUG WIRE REPLACEMENT Clean the wires and inspect them for burned, cracked or otherwise damaged wires. Check that the wire sheaths are installed on the direct ignition system module and spark plugs, and replace the wires, if necessary Expert advice: 1. Every 5000 kilometers or every 3 months, check the disc brake pads and drum brake linings, carefully check the thickness of the brake pads and friction linings, and if it is expected that the brake or friction linings will not be able to be made available until the next scheduled maintenance time, they should be replaced, check the brake fluid reservoir, and cap the brake fluid reservoir and the brake fluid reservoir. Check the brake fluid reservoir, cap, and top vent. Ensure that it is free of dirt and that the passages are clear. 2. Replace the air filter element every 10,000 kilometers, and shorten the air filter replacement intervals in dusty conditions. Owner's Manual: Storage of spare tire and jack Be alert for rattling noises at the rear of the vehicle. The spare tire, all equipment and tools must always be secured Lubricate the jack or screw mechanism with oil after each use. CLEAN OIL SYSTEM The smoothness of the oil system is essential for the stability of the vehicle while driving and for saving fuel. After driving for a long time, due to the climate, environmental changes, oil or driving habits and other influences, the engine injector nozzles and intake valves and other air intake system produces carbon deposits, of which the injector nozzles are close to the intake valves, the temperature is very high, the most likely to cause local high temperature oxidation of the oil, resulting in the injector nozzles carbon deposits. Carbon will reduce driving performance, increase exhaust pollution, fuel consumption and cold start bad idle shaking phenomenon, it is recommended that owners driving 20,000 kilometers after the injector should be cleaned once. This basic cleaning action is not difficult, it is recommended to use "full power fuel line cleaner", once the fuel tank, fuel lines, fuel injectors, carburetors, intake runners, combustion chambers and cylinder heads and other parts of the overall cleaning. In addition, modern high-performance engines use a multi-valve design with 3 to 6 valves per cylinder for a more complete intake and exhaust. Some engine design valve opening and closing time can be changed with the engine speed and load, but the gum affects the valve opening and closing time and opening and closing accuracy, if the intake valve is not smooth, it will not be able to provide the right amount of mixture of vapor, resulting in weak acceleration, low-speed wheezing, and even stalling phenomenon. In order to improve this situation owners can use "fuel additives" to clean the intake valve around the deposits, so that the engine horsepower recovery, as long as the tank is full of fuel, the cleaner will be poured directly into the tank can be recommended every 5000 kilometers of regular maintenance once. 1800 cc dimensions (length/width/height): 4533/1705/1490mm Theoretical fuel consumption: 4.7-6.2 liters / 100 kilometers engine reliability is good in the domestic car with a high popularity rate BYD F3 engine and transmission unit are very mature, the early models of the Mitsubishi 1.6-liter 4G18 and the later use of the Mitsubishi 1.5-liter 4G15S are Harbin, Dongan Mitsubishi engine plant production and production. Dongan Mitsubishi engine plant production and supporting the provision of. In the domestic models, 4G18 popularity is still very high, Southeast Lingshuai, Lancer, China Junjie and Hai Fuxing, etc. are equipped with. 4G18 engine production in China has a history of more than 10 years, the main advantages of a compact structure, high power, fuel efficiency. 4G18's fuel-saving know-how is MVV (Vertical Vortex Thinning Combustion), mixed gases in the intake partition and longitudinal vortex control piston *** with the role of the formation of a longitudinal vertical vortex in the cylinder, so that the concentration of the mixture in the cylinder from the inside to the outside of the gradual decrease in the ignition time adjusted by the ECU, so that the flame spreads the fastest speed in the cylinder. Through this point to improve engine thermal efficiency and reduce fuel consumption. In addition, the compression ratio of 4G18 engine is 9.5, which is in a relatively low range, so it can be better adapted to the domestic oil condition. This gives the 4G18 engine an excellent adaptability. What should I do if I meet the engine valve cover with oil stains? Early owners, especially those who bought BYD F3 in 2006, often find some oil stains on the valve cover of 4G18 engine. Many people are worried about this. Because the engine part of the oil stains indicate that the engine began to have oil leakage. The engine is the heart of the car, the heart if there is a problem, can not let people worry about it? Engine valve cover oil is actually very easy to find, without the need to distinguish between veteran or novice. After parking, we open the engine compartment cover, generally the first in the eyes of the engine valve cover (oil adding port in the engine valve cover on the plane). In general, the normal situation, the valve cover has a thick layer of dust, very normal, do maintenance, refueling to add the mouth of the oil spilled some oil to form an oil stain is also often there. But if the oil elsewhere should be generated by oil leakage. Master Zhou suggested: early BYD F3 users find this kind of problem do not worry. This small problem is fixed valve cover six screws torque is insufficient to cause. The reason for this problem is very simple: 4G18 engine is a cast iron cylinder block, aluminum alloy cylinder head, however, the valve cover is fixed in the aluminum alloy cylinder head, aluminum alloy relative to the cast iron strength to be softer, which determines the assembly time to reduce the appropriate torque, due to the six screws of the torque is not up to the standard requirements, or six screws of which a few of them meet the requirements, but the other ones do not meet the requirements! As the six screws do not meet the standard requirements, or some of the six screws meet the requirements, but the others do not meet the requirements, the oil leakage glitch will occur more or less in the future driving. The solution is actually very simple, is in accordance with the operating manual, the use of kilogram wrenches to re-tighten the six fixing bolts in diagonal order, this glitch will be solved. For some really unqualified screw products, we will generally take the replacement and fastening screws to deal with. Generally after the above treatment, basically no user reflects the valve cover with oil again. Advanced mold production line BYD's mold production line comes from Ogiwara, Japan, and the current mold production base is located in Tongzhou, Beijing, and the quality control personnel of the overall production line are all from Japan. There have been world-class famous enterprises and BYD mold contact and reached a cooperation intention, so in the mold technology and processing and manufacturing precision, the existing independent brands in the field of BYD's position unshakeable. What should I do if I have problems with the power windows? Many owners reflect BYD F3 glass lifter in the glass up and down, there is abnormal noise, glass lifting before and after the two ends of the rate is not the same, and even glass and lifter arm derailment problem. This problem is not only a common problem of BYD F3. It is not uncommon in many models in the same class, including even joint venture brands. Many car owners therefore suspect that some early or a batch of BYD F3 models power window lift parts have quality problems. Previously, we found this problem through the owner feedback, the method used is to spray the surface plate wax for the glass slush groove lubrication, if this phenomenon still exists after spraying wax, the general claimant will be based on the repairer's advice to declare a claim and then replace the parts, in the early days, this is a very effective method, however, many owners in the replacement of a brand new lifter assembly, not long or the same problem! The problem, this is a moment confused a lot of 4S repair master. In the end, where is the problem? After the group and other 4S maintenance personnel exchanges, we generally reflect that the electric window lifter itself does not have quality problems, but because the outside of the door and window glass connection and play a role in sealing the outer rubber strip and window glass pressure with too tight resulting in the glass through the lifter run by the extra force, in the long run, the lifter will inevitably be deformed as well as rattling, the motor is damaged by the fault. If the sealing strip, take down according to the width of the vehicle side door glass running mouth, as well as in the installation of the glass lifter position carefully adjusted, the problem will be effectively solved. Newer F3s have fewer of these problems, and older F3s usually have them more often. There are also some owners, is a glass mud trough problems, resulting in window lifting rattles and not smooth, spray sheet wax can only play a temporary lubrication, so customers are best to ask the 4S to be claimed for replacement, our 4S sheet metal group usually take the means of replacement, less than 20 minutes at most. Maintenance costs economic parts price is quite cheap Daily maintenance in the most is to replace the oil and oil filter routine maintenance, usually commonly known as "small maintenance", BYD F3 maintenance costs about only 140 yuan, is considered quite economical, even the independent brand A5, its small maintenance costs more than 200 yuan. Plus BYD F3 fuel consumption is not high, its cost of use and purchase of cost-effective as outstanding. BYD due to accessories homemade proportion is quite large, coupled with the current monthly sales maintained in the 10,000 units or even in the 20,000 units above, so the price of accessories in the same class of cars will usually be lower than the average, even with the same independent brand A5 and Vision compared to a slight advantage. What should I do if the clutch and gas pedal are hard? Many BYD F3 owners who have driven other brands usually envy other people's clutches and throttles are very light, while the F3 throttle and clutch feel a bit heavy, driving in the city, especially in traffic jams, will feel more tired. This problem, I believe, is the direction that BYD F3 needs to improve. For this problem, the usual solution of 4S is to clean the throttle and lubricate the clutch and throttle cable. Because the F3's clutch is not hydraulic and the throttle (throttle) is not electronic, it is usually easy to produce insufficient lubrication of the cable after a period of use. Of course, we can also partially adjust the throttle and clutch pull cables within the appropriate range according to user requirements. This helps to alleviate the problem of heavier throttle clutch. Key components are adopted from well-known large manufacturers Not only does the car engine adopt the batch products of large manufacturers, but even the engine EFI system, BYD F3 also adopts the supporting products of the globally famous Delphi. Like the familiar Bosch EFI products, Delphi's EFI also occupies a considerable share of the global market. BYD F3 is also one of the few independent brands to have an automatic transmission, which is still an imported product, from Japan's Aisin. The famous Volkswagen 6-speed manual transmission was also supplied by Aisin. What should I do if my car stalls? Products from large manufacturers are not necessarily problem-free. Many early F3 owners reported problems with stalling in traffic. Failure characteristics are very similar, F3 in the process of driving, into neutral for a moment (or upshift, downshift) the engine speed drops sharply, idle speed at 400 rpm -500 rpm, the engine power light flashes, and then is off. Judging from the fault phenomenon, it seems with the general EFI vehicles throttle valve body is too dirty or carbon caking lead to throttle work abnormal phenomenon, usually can be taken to remove the carbon, remove the gum, clean the injector, check the stepper motor and other methods, but for driving just a few thousand kilometers of the new car also appeared in this problem is difficult to use carbon to explain. After coordinating with the manufacturer, it was finally confirmed that the problem came from the throttle assembly, which was related to the software of the electronic control system. The problem has now been solved through two improvements. BYD manufacturers or supporting products to provide manufacturers mainly change the stepper motor bypass volume. Then combined with the electronic control software and ECU throttle first associated with the part, to solve the problem of engine stalling in the process of shifting gears. From a practical point of view, this improvement is quite effective. If the owner did not find this situation before, by chance this situation, must get in touch with 4S, and strive to solve the problem as soon as possible to eliminate hidden trouble. Configuration enough cost-effective super high on the price of BYD F3, space configuration are not bad. 2600 mm wheelbase in the class is considered mainstream. ABS + EBD, dual airbags, as well as 195/60 R15 tires, four-wheel disc brakes and other configurations are the first to open the F3 on the independent compact car precedent. What should I do if the antifreeze is leaking? Many users have reported leakage of antifreeze in F3, which can be found from the 4 ports connecting the engine and the water tank if observed carefully. For the current summer, car owners should find it as early as possible and repair it at 4S. In fact, you do not have to open the engine compartment cover to determine whether the engine antifreeze leakage. We can be based on normal driving conditions combined with the water temperature meter display to determine. If the engine water temperature in the 30 degree climate warms up faster, then you can judge that there is a leak. If the water temperature gauge is higher than the usual pointer position, can also be used as a basis for judgment of antifreeze leakage. If the owner of the car found when parking on the ground there is abnormal liquid (excluding air conditioning water and other factors) or F3 right wheel front half-axle liquid, most likely due to antifreeze leakage. Engine and water tank connected to the 4 interface leakage problem is relatively easy to solve, is to re-tighten the 4 water pipe clamps, of course, tighten the torque how much is also a learning experience: water pipe clamps may not be enough because of the torque, leading to leakage of antifreeze again, but not too much torque, resulting in water pipe by the unit pressure from the clamps to increase the pressure and fracture, of course, these data in the technical manuals issued to the various service stations are clearly indicated. Of course, these data are clearly indicated in the technical manuals issued to each service station. To ensure that the engine in the high speed and large load conditions, the coolant circulation rate increases. The 4G18 engine assembled in F3 has a dust cover that is not easy to check, and in the service station, when checking the problem of antifreeze loss, it is necessary to dismantle the dust cover and check whether the torque of the water pipe snap at this position meets the requirement. If it is not the interface leakage, then it is possible that the water pump and the cylinder block combined part of the seal is not tight, need to disassemble the pump to re-seal processing. If it is identified that the water pump is damaged, then the service station should claim a replacement for the customer. I personally think that the Jetta maintenance is cheap, fuel consumption is not high, very good, belonging to the popular models F3 it is a very good configuration, but the maintenance of some of the trouble as for the Le Feng well, I do not like it, huh! As for the choice of what models, you can according to your own preferences and conditions to consider!
