Fuel Injector Removal Note

NOTE:

Depending on the driving conditions, carbon may accumulate on the inserted part of the fuel injector, causing the fuel injector to stick. Remove the fuel injector using the following procedure.

Install the SST to the fuel injector confirming that the SST faces the correct direction as shown in the figure.
CAUTION:
- If the SST slips while ratcheting up the fuel injector, the fuel injector or surrounding parts could be damaged. Press fit the SST to the fuel injector firmly and operate carefully.
- When ratcheting up the fuel injector, the fuel injector connector may contact the cylinder head and damage the fuel injector. Ratchet up the fuel injector so that the fuel injector connector does not contact the cylinder head.

NOTE:
- If fuel injector NO. 3 contacts the oil separator, cut the tab on the oil separator as shown in the figure. Carefully cut the tab so that the oil separator is not deformed or damaged, with no clearance on the mating surfaces of the oil separator and engine.

Keep ratcheting the SST so that the fuel injector becomes free enough to ratchet up without using the SST.
CAUTION:
- Do not apply excessive force to the fuel injector connector because the fuel injector could be damaged.
Pull out the fuel injector by ratcheting it upright.
Verify that there are no gasket in the cylinder heads after removing the fuel injectors.
WARNING:
- If foreign material such as metal shavings penetrates the fuel injector installation hole on the cylinder block, the engine could be damaged. Remove all foreign material and cap the fuel injector installation hole after removing the fuel injector.
Clean the fuel injector and around the insertion hole using a vacuum cleaner.
