Injector

The first step to remove the 2AZ-FE engine fuel injector is to drain the system fuel pressure. The next step requires disconnecting the cable from the negative terminal of the battery. Start the removal procedure by first eliminating the No. 1 engine cover sub-assembly together with the air cleaner cap sub-assembly and its connected hose. Dispose of the fuel main tube properly by extracting it from the fuel hose clamp and fuel pipe clamp without deforming the tube. Following fuel tube connector cleaning install tool: 09268-21010 by fitting the retainer into the connector while using the tool's chamfered part. To disconnect the fuel tube use both hands to push its connector toward the tool until a "click" sound appears while mounting the retainer onto its chamfered part. The remaining fuel needs drainage from the tube followed by plastic bag coverage for protection. Use the tool 09268-21010 to disconnect the No. 2 ventilation hose from its position on the ventilation valve. Detach the sub-assembly of the fuel delivery pipe by unclamping the 2 wire harnesses and disconnecting the 4 fuel injector connectors while unfastening the 2 bolts to remove both fuel delivery pipe and 4 fuel injectors with caution against accidental drops. To complete the procedure remove first the 2 delivery pipe spacers and then the 4 insulators from the cylinder head before extracting the 4 fuel injectors from the fuel delivery pipe.

Install 4 new injector vibration insulators onto the cylinder head.

Take out the 2 bolts to disconnect the ground wires.

Push and pull to release them.

Tighten the 2 bolts to a torque of 20 Nm (205 kgf-cm, 15 ft-lbf).
