Install the upper O-Ring (1) on the injector sleeve (3) .Note: The upper O-Ring is dark blue.
Install the lower O-Ring (2) on the injector sleeve (3) .Note: The lower O-Ring (2) is turquoise.
Position the injector sleeve on the 221-9777 Sleeve Installer .
Apply a thin coat of 4C-9507 Retaining Compound around the outer circumference of area (A). Ensure that the retaining compound does not make contact with the O-Ring seal at any time.
Position the injector sleeve (3) in the cylinder head by using the 221-9777 Sleeve Installer .
Slowly push the injector sleeve into the cylinder head by gently tapping with a hammer.Note: Allow the 4C-9507 Retaining Compound to cure for two hours at 21 °C (70 °F) before filling the engine with coolant. Longer curing time is required for lower temperatures.
Install the unit injectors. Refer to Disassembly and Assembly, "Unit Injector-Install" to install the unit injectors.
