If obvious fault symptoms occur: such as engine starting difficulties, unstable idle speed, poor acceleration, power decline, increased fuel consumption, excessive exhaust emissions, etc., and after inspection, it is confirmed that the fault is caused by the injector nozzle failure, then it needs to be replaced. For example, the injector nozzle is blocked, resulting in uneven injection, making the engine cylinders work unevenly and causing jitter.

Long mileage: When the mileage of a general vehicle reaches about 80,000-100,000 kilometers, if the injector nozzle has not been cleaned or maintained, there may be varying degrees of carbon deposits and wear. At this time, you can consider checking the injector nozzle and decide whether to replace it according to the actual situation. However, this is only a rough reference mileage, which will also be affected by factors such as fuel quality and driving habits.

Poor fuel quality: If inferior fuel is used for a long time, impurities, colloids and other substances in the fuel are easy to accumulate at the injector nozzle, accelerating the clogging and wear of the nozzle. In this case, even if the vehicle has a short mileage, the injector nozzle may need to be replaced in advance.

During engine overhaul: During engine overhaul, in order to ensure the performance and reliability of the engine, the injector nozzles are usually thoroughly checked and replaced if there are any problems.

In daily use, regular cleaning and maintenance of the injector nozzles can extend their service life. If the fuel used in the vehicle is of good quality, the driving habits are good, and regular maintenance is performed, the injector nozzles may not need to be replaced during the entire life cycle of the vehicle. However, if the above abnormal conditions occur, the injector nozzles should be checked and repaired in time, and replaced if necessary to ensure the normal operation of the engine.
