How long to change common auto spare parts?
Engine oil is the soul of the engine, it can lubricate, clean, seal and prevent leakage, prevent rust and corrosion and cooling the engine. Known as the“Blood” of the car. If not replaced for a long time.
Over time, there will be an impact on the engine, carbon accumulation will lead to idle jitter, increased fuel consumption, power loss and accelerated engine parts wear, make this situation irreversible. Commonly used engine oil is generally divided into mineral oil, semi-synthetic oil and fully synthetic oil three.
Mineral oil: 6 months or 5000 km, semisynthetic oil: 8 months or 7500 km, fully synthetic oil: a year or 10,000 km. Oil selection should also be based on the engine working conditions to determine the requirements. Low oil viscosity will lead to low engine pressure, can not form a good oil film to protect the friction between parts.
As long as the selected oil viscosity is too high, will lead to poor oil fluidity, lubrication speed can not keep up with the running speed of the various parts, excessive oil, that is, greater than. Fuel gauge upper limit, will increase the movement resistance, reduce engine power. Therefore, the quality of oil, but also directly affect the life of different parts of the engine.
The main role of gasoline filter is to filter impurities and moisture in gasoline, if the gasoline filter is dirty or damaged, will cause weak acceleration, starting difficulties, non-reaction after repeated start. Gasoline filter is divided into: built-in steam filter and external steam filter. Replacement cycle: every 20,000 km or once a year.
Of course, according to the car environment and air quality to determine, if the city air quality is not good, the car environment is not good, it is best to reduce the replacement time. It is best to switch on after 1 or 2 changes in winter and summer. External filter replacement cycle: general every 20,000 -30,000 km need to replace once, located between the tubing.
Evaporation filter replacement cycle: generally every 60,000 to 80,000 km need to replace once, its location with the gasoline pump installed in the back tank. The specific replacement cycle also has many factors, in actual use, according to the quality of oil flexible adjustment. Replace the front brake pads every 30,000 to 50,000 miles under normal driving conditions.
Replace rear brake pads every 60,000 to 80,000 miles. Can also be replaced according to the degree of wear brake pads. In general, it is not smaller. More than 03 cm. Of course, this is not a fixed replacement cycle, because everyone’s driving habits are different, if the cycle and the number of kilometers to replace, not only will cause waste.
It can also cause excessive wear and tear, affecting safety. In general, the new car battery in normal conditions can use about 3-4 years, but after the second replacement usually takes about 2 years to replace, which has a lot to do with the quality of the battery. At the same time, battery life, driving habits, road conditions, car age and other factors are also important.
The function of the spark plug is to generate an electric spark to ignite the gas mixture in the cylinder. Automotive spark plugs are divided into three types by material: nickel alloy (ordinary copper core) , platinum spark plug (platinum) and iridium spark plug. Its life cycle of 30,000 km or 50,000 km, some models up to 100,000 km. The spark plug replacement period of direct injection engine should be shortened appropriately.
There is no doubt about the importance of tyres, their replacement cycle is usually four years or 80,000 km. If the sidewalls of your tires are cracked, replace them for safety, even if you haven’t reached mileage yet. When the tread depth is less than 16 mm, or the tread has reached the wear indicator mark, must be replaced.
The main role of air-conditioning filter is to filter impurities and dust in the air, to ensure that all fresh air into the car, activated carbon air filter has the role of adsorption odor. Its replacement cycle is twice. The specific replacement time should also be based on the driving environment of the car to determine, proposed every maintenance work as a key inspection items.
Timing belt is a very important part of the valve train system, when the tenon belt breaks, it will cause damage to the engine. General timing belt replacement cycle is 60,000 km, and later some models of timing belt manufacturers also have 100,000 km warranty, so our replacement cycle can be replaced after the warranty lifted.
1.What are the exterior modifications?
Auto body appearance of the modification has been occupying a very important position, mainly including lacquer (stickers) , color-changing film, big envelop, tail, cover, fender and so on.
1) Auto sticker
Lacquer is usually refers to the body of a variety of stickers on the design, generally can be a brand LOGO, color patterns or animation image; the role is to enhance the appearance of identity, personalization.
2) Color-changing film
Color-changing film is made of vinyl polymer material with a variety of colors, can directly cover the body, and then change the whole body or a part of the body color.
3)Auto body kits
The automobile encirclement modification generally divides into the big encirclement and the small encirclement, the big encirclement generally refers to the front, the rear bumper, the side skirt overall replacement;. Retrofitting enclosures can be aesthetically pleasing, personalizing, spoiling, and even improving aerodynamics performance.
4) Auto spoiler
The tail fin is known as the tail spoiler, which can be divided into duck tail, bridge fixed tail, GT tail and so on, and the retrofit of the tail fin can improve the aerodynamics, increase the tail pressure and other effects.
5) Auto hood and fender:
a: cover refers to the engine cover, the original general iron, modified different materials of the cover can play a lightweight effect, if the selection of the cover with a cooling hole design, can also play for the cabin cooling effect.
b: Auto fender retrofit is generally with a heat sink hole design or is a wide body effect.
2. Appearance modification parts, how to choose?
