Title: 2GR-FKS (FUEL): FUEL INJECTOR (for Direct Injection): INSTALLATION; 2018 - 2024 MY Camry [06/2017 -        ]

INSTALLATION

PROCEDURE

1. INSTALL FUEL INJECTOR SEAL

(a) Apply engine conditioner to the area shown in the illustration. Using a piece of cloth, clean carbon deposits from the fuel injector assembly and its grooves.

NOTICE:

  • Do not clean the tip of the fuel injector assembly.
  • Do not use a wire brush to clean the fuel injector assembly.
  • If a fuel injector assembly is dropped or the tip of the fuel injector assembly is struck, replace it with a new one.

(e) Slowly slide SST (guide) toward the tip of the fuel injector assembly. When the fuel injector assembly contact surface of SST (guide) aligns with the fuel injector seal as shown in the illustration, hold the position for 5 seconds or more to fully seat the fuel injector seal into the fuel injector assembly groove.

SST: 09260-39021

09261-03020

NOTICE:

Make sure the fuel injector seal is not pinched between SST (guide) and the edge of the fuel injector assembly groove. Replace the fuel injector seal if it becomes damaged.

HINT:

  • Set SST (guide) so that its bottom surface is flush with the fuel injector seal.
  • If it is difficult to slide SST (guide) upward, slowly wiggle it from side to side while sliding it up the fuel injector assembly little by little.

(f) After installing the fuel injector seals, check that they are not scratched, deformed or protruding from the fuel injector assembly groove.

NOTICE:

If a fuel injector seal is scratched, deformed or protruding from the groove, replace it with a new one.

HINT:

Use the same procedure to install the other fuel injector seals.

NOTICE:

  • Check that there is no foreign matter or damage on the O-ring groove of the fuel injector assembly.
  • Make sure that the No. 1 fuel injector back-up ring is installed in the correct orientation.
  • Make sure that the No. 1 fuel injector back-up ring and O-ring are installed in the correct order.
  • Check that the opening of the No. 1 fuel injector back-up ring is not overlapped or stretched as shown in the illustration.
  • After installing the O-ring, check that it is not contaminated with foreign matter and is not damaged.

(c) With the notch of a new No. 3 fuel injector back-up ring facing downward, install the No. 3 fuel injector back-up ring to each fuel injector assembly as shown in the illustration.

NOTICE:

  • Make sure that the No. 3 fuel injector back-up ring is installed in the correct orientation.
  • After installing the No. 3 fuel injector back-up ring, make sure there is no damage or foreign matter.

NOTICE:

  • Make sure that there is no foreign matter or damage inside the fuel injector assembly installation holes (fuel delivery pipe with sensor assembly LH and fuel delivery pipe RH).
  • Do not allow gasoline to get on the O-rings or inside the installation holes.
  • If it is difficult to insert the fuel injector assembly, apply new engine oil to the chamfer of the fuel injector assembly installation hole of the fuel delivery pipe with sensor assembly LH and fuel delivery pipe RH. Be careful not to allow the fuel injector assembly to fall out of the fuel delivery pipe with sensor assembly LH or fuel delivery pipe RH.
  • Do not tilt the fuel injector assembly when inserting it into the fuel delivery pipe with sensor assembly LH and fuel delivery pipe RH.
  • Check that there is no gap between the fuel delivery pipe with sensor assembly LH, fuel delivery pipe RH and the nozzle holder clamp.
