1. Use Tooling (B) to clean the bore for the electronic unit injector in the cylinder head. Hold
Tooling (B) with Tooling (C). Rotate Tooling (B) against Surface (X) of the bore. Continue
cleaning until Surface (X) is smooth and shiny.
2. Use Tooling (D) to remove the fuel from the cylinder. Evacuate as much fuel as possible from
the cylinder before installing the electronic unit injector. Several evacuations may be necessary.

When an electronic unit injector is replaced, the new electronic
injector code must be programmed into the engine's personality
module software by using the calibration menu on the Electronic
Service Tool. If the new electronic injector code is not entered, the
characteristics of the previous electronic unit injector is assumed.
If it is not possible to immediately reprogram the electronic injector
code into the personality module software, the engine will not be
severely harmed. The new electronic injector code should be
reprogrammed as quickly as possible in order to optimize engine
performance.
5. Position electronic unit injector (5) into the original location in the cylinder head. Center the
solenoid between the valve springs. Press the electronic unit injector into the cylinder head. Do
not strike the electronic unit injector.

6. Install plug (4) in the cylinder head.
7. Install electronic unit injector clamp (3) and bolt (1). Tighten bolt (1) in order to seat electronic
unit injector (5) in the cylinder head. Do not strike the electronic unit injector. Tighten bolt (1)
to a torque of 65 ± 7 N·m (48 ± 5 lb ft).
8. Connect harness assembly (2). Tighten the terminal nuts to a torque of 2.5 ± 0.25 N·m
(22 ± 2 lb in).
