Do imported cars have a certificate of conformity?

Imported cars do have a certificate of conformity, which is another important document for the vehicle and is essential for registration. Only cars with a certificate of conformity meet the national requirements for motor vehicle equipment quality and related standards. The number on the certificate must match the engine number and chassis number on the vehicle. You can compare the date and engine number on the certificate with those on the vehicle, but this is not absolute—it only indicates that the vehicle may be newly produced, not necessarily brand new. The chassis number is the VIN code, which is more like the body number and matches the entire vehicle. The engine number is the serial number of the engine itself.

What to Do When Engine Temperature Rises?

When the engine temperature rises, the first thing to check is whether the radiator coolant is normal, and whether there are any leaks in the radiator, cooling hoses, or other components. If no abnormalities are found and only the coolant level is low, you can continue driving after replenishing the coolant. If the coolant level decreases again after driving for a while, it is likely that there are sand holes or perforations in the cylinder block causing the coolant loss. If there is air in the car's cooling system, it can easily form an air lock, leading to poor circulation in the car's radiator and resulting in excessively high engine temperature. In this case, an air bleeding process should be performed.
