1. Below is a description of how to remove the injectors for the Z16XE/Z18XE engines. For engines other than the Z22YH engine, this procedure is similar, but some additional work may be required to free access to the fuel rail and injectors. On the Z22YH engine, the injectors are installed according to the principle of a diesel engine - a special tool will be required to remove the injectors from the head (see accompanying illustrations).
14.1a Install the KM6360 tool (1) and, by smoothly turning the injector, loosen its fit in the cylinder head seal (z22YH engine)
14.1b Using the KM-328-B tool (1), remove the injector from the cylinder head (z22YH engine)
Removal
2. Disconnect the cable from the negative battery terminal and remove the engine cover.
3. Disconnect and remove the air intake duct from the air cleaner to the throttle body assembly and relieve the fuel system pressure.
4. Raise the vehicle on a lift and disconnect the electrical wiring connectors of the following sensors and devices:
- Post-catalytic lambda probe;
- Engine oil pressure sensor;
- Crankshaft position sensor;
- Oil level control sensor;
5. Lower the car onto its wheels.
6. Disconnect the camshaft position sensor wiring connector and disconnect the ground cable from the generator.
7. Disconnect the fuel line from the fuel distribution line using a special tool Hazet 4501-1 (see accompanying illustration). When disconnecting the line, cover the connector with a rag to prevent fuel from splashing, then plug the fuel hose and move it to the side.
14.7 Disconnecting the fuel line using a special tool (1)
8. Disconnect the wiring connectors of the following sensors and devices:
- Compressor;
- Coolant temperature sensor;
- Air Conditioner Pressure Sensor;
- Throttle control module;
- Engine Control Module (ECM);
- Knock sensor;
- Ignition module;
- Injection injectors;
- Pre-catalytic lambda probe.
9. Remove 2 mounting bolts (see accompanying illustration) and remove the fuel distribution line together with the injectors from the engine.
14.9 Bolts (indicated by arrows) fastenings
10. Remove the retaining clips one by one (see accompanying illustration) and remove the injectors from the fuel distribution line.
14.10 Fastening the injectors (2) to the fuel distribution line (3): 1. Locking bracket; 4. Sealing gaskets
Installation
11. Replace the injector sealing rings and lubricate them with silicone grease (white color).
12. Install the injectors on the fuel distribution line, while the retaining clips should be inserted so that the protrusion on the injector fits into the groove of the clip (see accompanying illustration).
14.12 Installing the locking bracket
13. Install the fuel distribution line and tighten its fastening to the required force.
14. Further installation is carried out in the reverse order of removal.
