2005 Toyota RAV4 Parts Questions & Experts Answers

• Q: How to remove and install a fuel injector while ensuring proper handling of the O-ring on 2005 Toyota RAV4?

  A: Use spindle oil or gasoline to coat a new O-ring before adding it to its position because the O-ring and the new ones should never be reused and both must be handled gently to prevent damage. Begin by disconnecting the PCV hose before taking out the air cleaner assembly with MAF meter by disconnecting the MAF meter connector along with the VSV hose for CCV then removing 3 bolts to remove the entire assembly piece. To proceed disconnect the 4 injector connectors before removing the 2 bolts securing the delivery pipe to the cylinder head and safely disconnect the delivery pipe with its 4 injectors from the cylinder head while maintaining the injectors from falling. Few steps are required to remove the delivery pipe injectors including pulling out the 4 injectors from the delivery pipe while also removing the O-ring from each injector. A thin layer of spindle oil or gasoline should first coat a new O-ring before placing it on each injector. Then position the 2 spacers and 4 new grommets on the cylinder head. Use spindle oil or gasoline as a coating on the delivery pipe area touching O-rings before pushing the injector into delivery pipes and turning it for complete installation of the 4 injectors with downward connector orientation. Check that the injectors can turn properly after attaching the delivery pipe with 4 installers to the cylinder head temporarily using the two bolts; poor rotation requires replacement of the O-ring. Place the injector connectors in the downward direction before applying 20 Nm (15 ft.lbf) torque to the 2 bolts then attach the 4 injector connectors. Put back the air cleaner assembly and the MAF meter followed by PCV hose reconnection.
