When is the car overhauled? What does it contain?

About1-20 thousand kilometers is medium maintenance, including cleaning the three-way catalyst of throttle nozzle and replacing the steam filter. The major maintenance of about 40,000 kilometers includes cleaning the three-way catalytic converter of throttle nozzle, replacing steam filter, gearbox oil, brake oil and booster oil, and replacing antifreeze for more than two years.

Replace the necessary filters and fluids. Change the engine oil and oil filter regularly, because over time, they will also lose important performance-such as the ability to take away heat, lubrication and rust prevention and cold protection. Ensure routine inspection. The user manual has a maintenance schedule. Another advantage of having the same technician always serve you is that he can ensure that you stick to this maintenance plan and consider what is not included in the manual for you. If you go to a different shop every time you repair your car, the technicians in the shop don't know what happened to your car last time. So, you may end up paying for unnecessary maintenance. And if you insist on doing maintenance in a store, because most stores have electronic records, technicians know when to arrange what services. Check the cooling system of the car. Ensuring that your car's cooling system works properly and has enough coolant can potentially save you a lot of maintenance costs. Replacing your air filter will help your car breathe more easily and make the engine life longer. In order to run, the engine needs an accurate mixture of fuel and air, and all the air enters the engine system through the air filter. Its purpose is to prevent dust and other foreign objects from entering and damaging the engine. Take care of the tires of a good car. Tires are often the most easily overlooked part and the lowest maintenance cost.
