Toyota Camry 65438+ 10,000 kilometers, where should it be maintained?

Toyota Camry of Pacific Auto Network is 654.38+10,000 kilometers. In-depth maintenance is to clean and maintain the internal structure of the vehicle that affects its performance, safety and reliability. Such as engine, gearbox and three-way catalytic converter.

Generally, the in-depth maintenance of automobiles is based on the principle of no disassembly, and professional equipment and professional cleaning products are used for professional operation. So that the interior can be cleaned efficiently without dead ends, and the original locomotive performance of the vehicle can be maintained. Simplify the repair and disassembly procedures, so as to avoid disassembly and reassembly from damaging the mating state between the original accessories. It is suggested that the Camry should be deeply maintained for the following items. First, clean up the engine carbon deposit. This Camry has been driven for nearly 300,000 yuan, and the noise of the machine will become louder and louder, and the idle speed will become unstable. There must be a lot of carbon deposits inside the engine. Such as piston top, valve port, cylinder head top, fuel nozzle and spark plug, there are colloid deposits and carbon deposits attached to them. The volume of the combustion chamber becomes smaller and the working efficiency becomes worse. Then the engine must be thoroughly cleaned by carbon deposition. Specifically, it is to use special equipment and special engine carbon deposit cleaning agent to clean the inside of the engine. The cleaning agent will decompose the carbon colloid and eventually be discharged with the exhaust gas. If the carbon deposit is serious, there is no choice but to remove the cylinder head for thorough cleaning.

Second, clean the fuel injector, throttle and air inlet. Generally, the throttle needs to be cleaned after 20-30 thousand kilometers. If the carbon deposit is not serious, it can be removed and cleaned. Like this Camry, the throttle valve needs to be removed and thoroughly cleaned inside and outside, and the nozzle and air inlet need to be removed for deep cleaning. Carbon deposition in the fuel injector will lead to insufficient fuel injection, decreased engine power and increased fuel consumption.

Third, clean the gearbox. AT gearbox needs to remove gearbox oil pan and replace gearbox oil, gearbox filter element and gearbox oil bottom pad. You can also use special equipment to connect the transmission cooling oil pipe for disassembly and cleaning. This needs professional operation.

Fourth, clean the three-way catalytic converter. This Camry, almost 300,000 kilometers, will definitely have carbon deposits in the three-way catalytic converter. If it is not cleaned, it is difficult for the vehicle to speed up, the fuel consumption will increase, the noise will be loud, and the exhaust emissions will not be smooth and will not meet the standards. If the honeycomb of the three-way catalytic converter is found to be damaged before cleaning, it needs to be replaced. It needs to be cleaned with a special cleaning agent for three-way catalytic converter. The specific operation process needs professionals to perform.

Fifth, clean the cooling system. Problems with the cooling system will lead to high water temperature and serious damage to the engine. Therefore, Camry of 12 years needs to replace antifreeze, and carry out rust and scale removal cleaning on the water tank and cooling pipe.
