Removal and Installation
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug
openings to prevent fluid from spilling.
REMOVAL
- Remove engine room cover. Refer to EM-46, "Exploded View".
- Remove air cleaner body. Refer to EM-25, "Exploded View".
- Disconnect the radiator hose (upper) from the water outlet. Refer to
CO-15, "Exploded View".
- Disconnect water hoses from electric throttle control actuator
- Disconnect electric throttle control actuator harness connector.
- Remove electric throttle control actuator.
CAUTION:
- Handle carefully to avoid any shock to electric throttle control
actuator.
- Do not disassemble electric throttle control actuator.
- Pull out oil level gauge.
CAUTION:
Cover the oil level gauge guide openings to avoid entry of foreign
materials.
- Disconnect vacuum hose and EVAP hose from intake manifold.
- Disconnect PCV hose from intake manifold.
- Disconnect harness connectors from the runner control valve, runner
control valve position sensor, and
the tuning valve.
- Loosen intake manifold nuts and bolts in the reverse order as
shown.
: Engine front

NOTE:
Disregard the numerical order No.6 in removal.
CAUTION:
Cover engine openings to avoid entry of foreign materials.
- Remove intake manifold and intake manifold gasket.
INSTALLATION
Installation is in the reverse order of removal.
Intake Manifold
- Securely install intake manifold gasket to the mounting groove of the
intake manifold.
CAUTION:
Do not reuse intake manifold gasket.
- Install intake manifold with the following procedure:
- Tighten intake manifold nuts and bolts in the numerical order as
shown.
- Tighten No. 1 bolt again.

- Tighten bolts of electric throttle control actuator equally and
diagonally in several steps.
NOTE:
After installation, it is necessary to re-calibrate the electric throttle
control actuator as follows:
- Perform “Throttle Valve Closed Position Learning” after repair when
removing harness connector of the electric
throttle control actuator. Refer to EC-139, "Description".
- Perform “Idle Air Volume Learning” after repair when replacing
electric throttle control actuator. Refer to EC-
140, "Description".
INSPECTION AFTER INSTALLATION
Check for engine oil leaks and engine coolant leaks with engine at operating
temperature and running at idle.
WARNING:
Do not touch engine immediately after stopping as engine is
extremely hot.
