Using a 19 mm (0.74 in) socket, 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 of snap rings 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: If engine oil is found in the engine coolant or engine coolant is found in the combustion chambers, new injector sleeves may need to be installed.
Remove the bolt, the fuel injector hold down and the fuel injector.
NOTE: If a snap ring or piece of a snap ring is missing from the injector hold-down assembly, it must be located prior to removing the shop towels.
Remove the shop towels.
