Actuator-Swirl Valve
DESCRIPTION

The swirl valve linkage links the swirl valves
in the intake manifold to the swirl valve
actuator.

The swirl valve linkage has two different
style clips. The square clip (1) is a two piece
design, and the round clip (2) is a one piece
design.

Linkage-Swirl Valve
DESCRIPTION

The intake manifolds feature swirl intake
ports to reduce particulates at low engine
speeds. Each cylinder incorporates one swirl
port and one charge port. The swirl ports can
be closed by the swirl valves. The valves are
connected together via a linkage which is
operated by the swirl valve actuator.

The swirl valves are normally open by spring
tension. The spring is integral with the swirl
valve actuator. In the lower engine speed and
load range, the swirl valves are closed by the
swirl valve actuator. The entire air mass
flows through the charge ports only, which
results in greater swirling. The increased
swirling produces uniform combustion for better engine performance and reduction of
particulates. As rotational speed and load increases, the swirl valves open, so that optimal
swirling and the required air mass are provided for the current operating conditions.

The linkage between the swirl valve actuator
and the intake manifold has two different
style clips. The square clip (1) is a two piece
design, and the round clip (2) is a one piece
design.

REMOVAL

1. Disconnect negative battery cable. (Refer

to 8 - ELECTRICAL/BATTERY
SYSTEM/CABLES - REMOVAL)

2. Remove the engine cover. (Refer to 9 -

ENGINE - REMOVAL)

3. Drain the coolant. (Refer to 7 - COOLING

- STANDARD PROCEDURE)

4. Remove the strut tower support (2).

5. Remove the intake air housing and tube.

(Refer to 9 - ENGINE/AIR INTAKE
SYSTEM/AIR CLEANER HOUSING ­REMOVAL)

6. Remove the charge air cooler tube (4).

7. Remove the resonator.

8. Remove the EGR tube.

CAUTION: Observe the position of the
turbocharger oil passage housing and
gasket. Failure to properly position the gasket during assembly will result in immediate
turbocharger failure after assembly.

9. Remove the turbocharger (3). (Refer to 11 - EXHAUST SYSTEM/TURBOCHARGER

SYSTEM/TURBOCHARGER - REMOVAL)

10. Disconnect the engine harness and
position aside.

11. Disconnect the swirl valve actuator
connector.

12. Remove the swirl valve actuator (3) clips.

13. Remove the swirl valve actuator.

INSTALLATION

1. Assemble the two halves of the square clip
around the actuator arm, and place a 5/16” O­ring (2) around the base of the clip (1) to hold
it together.

2. Position the clip into the actuator arm and push
the clip partially into the arm.

3. Cut the O-ring and press the clip the rest of the
way into the actuator arm. Make sure the clip
clicks into place.

4. Install the swirl valve actuator. Tighten the bolts to 8 nm (44 lbs. in.).

5. Connect the swirl valve connector.

6. Position and connect the engine harness.

CAUTION: Observe the position of the turbocharger oil passage housing and gasket.
Failure to properly position the gasket during assembly will result in immediate
turbocharger failure after assembly.

7. Install the turbocharger. (Refer to 11 - EXHAUST SYSTEM/TURBOCHARGER
