Using the special tool, push the fuel injector electrical connector out of the rocker arm carrier.
Prior to removing the injector assembly, insert clean shop towels in the oil drain holes adjacent to each glow plug.

CAUTION: Failure to account for all snap rings or pieces prior to placing the vehicle back in service can cause engine damage. A missing snap ring can be ingested into the lube oil system, causing severe engine damage.

CAUTION: To prevent engine damage, do not use air tools to remove the fuel injectors. The snap ring that extracts the injector can dislodge and fall into the oil drain hole.

NOTE: There is no need to drain the fuel rail.

NOTE: If engine coolant is found in the combustion chambers, it may be necessary to install a new injector sleeve. For additional information, refer to FUEL INJECTOR SLEEVE in this article.

NOTE: Use a tool like Snap-On®R SDMT440 torx to avoid damaging the fuel injector plastic and to avoid interference with the evaporator case.
