Installation
For the installation, reverse the removal proce-
dure. Paying attention to the following details.
If you reinstall a used injector, carefully inspect
O-ring condition before reinstalling fuel injector.
Replace O-ring with a new one if damaged. In-
sert the fuel injector in place with your hand.
NOTE: A thin film of engine oil should be applied
to O-rings to ease insertion in fuel rail and intake
manifold.
Apply Loctite 243 on rail retaining screws then
torque to 10 N•m(89lbf•in).
When installing fuel line connector to the fuel rail,
put some oil on the O-ring to ease installation.
WARNING
Perform a fuel pressure test and ensure that
there is no leak. Refer to FUEL SYSTEM sec-
tion.
THROTTLE BODY
IMPORTANT: Never mix up throttle bodies of
naturally-aspirated and supercharged 4-TEC en-
gines. Doing so will automatically lead to a
misfunction of the EMS and will cause a bad
engine calibration.
