Install the remaining parts of Tool B on the threadedrod assembly (item 6).
Lubricate the threads on (item 6).
Tighten nut (item 1) in order to remove the unitinjector sleeve. Do not use an impact wrench.
After the sleeve is removed, use the large 4C5552wire brush to remove dirt and sealant from the bore. Squirt isopropyl alcoholor brake cleaner into the bore to remove oil. Use paper towels and swabsto remove all debris from the bore. Ensure the injector bore and fuel railare clean and free from debris.
Any sealant, fuel, oil or debris willprevent the sealant from properly curing. Improper cleaning will lead toa poor sealing surface and leak path.

Surfaces to be sealed must be freeof oil, grease, fuel, etc.
Install the unit injector sleeve into the injectorsleeve bore.
Use a hammer to drive the sleeve into the headuntil the sleeve bottoms out.
Wipe all excess anaerobic from the injector borewith a paper towel and swab.
Stamp AH on the front left top of the cylinderhead near the HEP 8 pump to verify the rework has been completed.
Wait approximately two (2) hours atroom temperature (70F) before filling the engine with fuel or coolant.Longer curing time is needed at lower temperatures.Unit injectors ? Installation procedure
