The injector is a key component of the engine fuel system, and its working condition directly affects the engine performance and emissions. This Injector Repair Kit is designed for repairing the injector, and the following are detailed instructions for use.

Before starting the repair, please make sure you have the basic knowledge and skills of automotive repair and prepare the necessary tools, such as wrenches, screwdrivers, and so on. Also, be sure to operate in a well-ventilated and safe environment, and strictly prohibit working near open flames or flammable materials.

First, carefully remove the injectors from the engine and mark the position of each injector so that they can be correctly positioned during subsequent installation. Avoid collision or damage to the injectors during disassembly.

Open the injector repair kit and check if the parts are complete and undamaged. Usually the kit contains seals, screens, spool valves and other key components.

Clean the disassembled injector thoroughly to remove oil, carbon and other impurities on the surface. Specialized injector cleaners can be used with ultrasonic cleaning equipment to achieve the best cleaning results.

Carefully inspect all parts of the injector to determine the parts that need to be replaced. Remove the old seals, filters, etc. from the injector using the appropriate tools. Be careful how hard you work when removing to prevent damage to the injector body.

Install the new parts from the repair kit onto the injector in the correct order and method. For example, install the new screen first to ensure that it is firmly installed and correctly positioned; then install the seals, making sure that they are not twisted or broken, and that they fit evenly on the corresponding sealing surfaces.

When installing precision parts such as valve spools, extra care should be taken to avoid impurities or damage. After the installation is completed, a simple manual test can be performed on the injector to check whether its spool movement is smooth.

Reinstall the repaired injector on the engine according to the previously marked position and connect the fuel line and other related parts correctly. After the installation is completed, start the engine for testing and observe the engine's running status, idle stability and exhaust emissions.

If the engine is found to operate abnormally during use, such as increased shaking, decreased power or black smoke, etc., it should be stopped immediately and the installation and working condition of the injector should be checked, and the relevant parts should be repaired or replaced if necessary.

The use of injector repair kits for fuel injector repair can effectively extend the service life of the injector, reduce maintenance costs, while helping to maintain good engine performance. However, please note that if you are unfamiliar with the repair operation or encounter complicated problems, it is recommended to seek the help of a professional auto mechanic.
