A range of operations such as preparation for oil replacement, hot vehicles, run-off oils, filters, new oils, liquid tablets, etc. First, we have to prepare for the engine preheating tools such as the fit oil, filters and wrench. The oil filters were then replaced after the oil bolts were released from the base of the flat ground grinding development motive. The new oil reference manual controls are then entered from the point of reference. When the engine is finally operational, check the fluid levels of the engine to ensure normality。
The selection of suitable oil must be based on the vehicle user manual during the preparatory phase. Modern run-off usually applies to oils of the standard 5w 30 or 5w 40 to be determined according to the environment in which the vehicle is used, the mileage travelled and the plant's recommendations. They also have tools such as oil filters, oil screws, wrenchs, jacks, oil basins, etc。
It is also critical to activate the hot link to allow the engine to operate for a few minutes to allow for the full flow of oil and subsequent discharge of old oil。
When the vehicle was parked on the flat ground and the hand brakes were pulled to open the hood of the engine, it was possible to find an oil bolt at the bottom of the engine. Wrenching with the wrench slowly allows old engine oil to flow into the pipeline to avoid spilling oil during the operation. Once the old oil has been released, check for damage to the oiled bolts and if necessary replace the new oiled screws before they are tightened。
Next, the oil filters are replaced and the old filters are carefully wrenched with a wrench. Evenly coating of a new engine oil on the seals of the new filter will serve as a good seal. New filters will be installed with hands to be sharpened and further strengthened with tools。
It then begins to bet on new engine oils and finds that it is best to use the funnel slowly to pour into new engine oils. The vehicle user manual is the subject of strict reference at this time to determine that not too much or too little should be done。
The start of the engine for a few minutes after the bet is completed allows the new oil to be fully recycled. The engine was then shut down, awaiting a few minutes of extraction and cleaning, and re-inserted to examine the fluid levels of the machine. If the fluid is insufficient, an appropriate amount of engine oil is required。
In short, every step to replace the oil with a modern vibrator needs to be rigorous. Any oversight between the preparation of the previous period and the various stages of the replacement process and the final inspection may affect the performance and lifetime of the engine. If you are not confident enough to operate, you can also go to a professional maintenance shop for replacement。
According to the langdong car purchase manual, longdong needs to replace 50 ngk spark plugs (4 at a time) per 160,000 km. However, at the 4s store, the spark plugs will be replaced on the basis of vehicle usage。
I. How to judge the lifetime of the spark plug
The spark plug is an important component of the normal operation of the engine. When mixed gas is inhaled and compressed, the work must be done by spark plugs, so that, to some extent, the performance of spark plugs will directly affect the ignition and explosion of mixed gas. However, the electrodes of spark plugs will also be consumed during this ignition. On the basis of the melting point and hardness of the electrode material, the electrodes are gradually depleted. When the gap between electrodes is too large, the vehicle will suffer from reduced power, cold start-up difficulties and increased fuel consumption. At this point, it is advisable to consider replacing spark plugs. In general, the normal life of the spark plugs in ordinary domestic vehicles is around 20,000 kilometres. In addition, in order to prolong the durability of spark plugs, some manufacturers use precious metal materials such as platinum, neptunium and, at the same time, they increase the intensity of ignition energy。
Ii. Need to upgrade spark plugs
In general, the original spark plugs have been rigorously tested at the plant and are fully capable of meeting the daily driving requirements, achieving the best balance of economy and power. However, due to cost-control factors, the original spark plugs would not normally be selective and better, so some car owners pursuing extreme performance could also consider the appropriate upgrade. However, promotions should follow the following principles: the spark plug model should match the engine type of the car. Thermal values are an important reference indicator for the selection of spark plugs. The heat of the pyrotechnic pyrotechnics is generally considered for all roads, but there are also retrofitters who like to upgrade to high-heat pyrotechnics. It is important to note that, while high-heat spark plugs are more suitable for high-speed motors, excessive carbon accumulation is generated if used for long-term traffic jams, and therefore the medium-heat spark plugs should be selected for use. 3. In the case of new vehicles that do not have a quality assurance period, some manufacturers refuse to provide quality assurance services if the spark plugs are replaced privately。
Iii. How to replace their own spark plugs
Although the position of the spark plug is important, it is easy to remove it. In general, most of the spark plugs were exposed outside the engine (except for some high-end vehicles). Just turn on the engine pad and pull out the high-pressure line attached to it, the spark plug will be exposed to you. But if you want to unplug yourself, you need some common sense. First, the pyrotechnic plug must be removed with a professional hexagonian wrench, and the external oil must not be allowed into the gas tank during the entire disassembly installation, and then the pyrotechnic plug must be tightened in accordance with the vertical pyrotechnic principle。
In fact, another benefit of replacing the spark plugs is the early detection of car failure. You can see the color of the spark plug, for example. If black carbon is covered in the vicinity of the electrodes, this indicates that the car was not burned well enough during this period, that the gas was over-heated and that the engine oil could be the main culprit. When red brown was found near the electrodes, it was proved that the petrol used recently was inadequate and that fuel quality needed to be taken into account to avoid greater losses. In any case, it is possible not only to develop feelings for cars, but also to learn more about cars。
