Injectors Installation

1. INSTALL INJECTORS AND DELIVERY PIPE
- Install 2 new grommets to each injector.
- Apply a light coat of gasoline to 2 new O-rings and install them to each injector.





- While turning the injector clockwise and counterclockwise, push it to the delivery pipe. Install the 6 injectors.
- Position the injector connector outward.





- Place the 3 spacers in position on the intake manifold.
- Place the 6 injectors together with the delivery pipe and 3 bolts in position on the intake manifold.
- Temporarily install the 3 bolts holding the delivery pipe to the intake manifold.





- Check that the injectors rotate smoothly.

HINT:
- If injectors do not rotate smoothly, the probable cause is incorrect installation of O-rings.
- Replace the O-rings.

- Position the injector connector upward.
- Tighten the 3 bolts holding the delivery pipe to the intake manifold.

Torque: 21 Nm (210 kgf.cm, 15 ft.lb.ft.)

2. INSTALL ACTUATOR FOR ACIS
- Install the actuator with the 2 bolts.

Torque: 6.8 Nm (70 kgf.cm, 61 in.lb.ft.)

- Inspect the intake air control valve.

3. CONNECT INJECTOR CONNECTORS.

HINT: The No.1, No.3 and No.5 injector connectors are dark gray, and the No.2, No.4 and No.6 injector connectors are gray.

4. CONNECT VACUUM SENSING HOSE





5. INSTALL AIR INTAKE CHAMBER STAYS
- Install the intake chamber stay with the bolt and nut. Install the No.1 and No.2 stays.

Torque: 18 N.m (185 kgf.cm, 13 ft.lb.)

HINT: The No.1 stay is marked with F and No.2 stay is marked with "R".

6. CONNECT FUEL RETURN PIPE TO FUEL PRESSURE REGULATOR.
- Connect the fuel pipe with 2 new gaskets and the union bolt.

Torque: 27 N.m (280 kgf.cm, 20 ft lb.)

7. CONNECT FUEL INLET PIPE TO DELIVERY PIPE
- Connect the fuel pipe with 2 new gaskets and the union bolt.

Torque: 42 N.m (420 kgf.cm, 30 ft.lb.)

- Install the No.2 vacuum pipe and VSV assembly with the 2 nuts.

Torque: 27 N.m (280 kgf.cm, 20 ft.lb.)





8. INSTALL THROTTLE BODY AND INTAKE AIR CONNECTOR ASSEMBLY.
- Place the gasket so the protrusion face the intake chamber, and set the throttle and intake air connector assembly.
- Connect the 2 water bypass hoses to the throttle body.
- Connect the vacuum hose (from the actuator) to the No.1 vacuum pipe.
- Install the intake air connector with the 4 bolts and 2 nuts.

Torque: 21 N.m (210 kgf.cm, 15 ft.lb.)

- Install the nut holding the VSV to the chamber stay.
- Connect these connectors:
- w/TRAC:
Sub-throttle actuator connector.
- w/TRAC:
Sub-throttle position sensor connector.
- IAC valve connector.
- Throttle position sensor connector.
- VSV connector for EGR.
- Connect these hoses:
- PCV hose to intake air connector.
- 3 vacuum hoses to No.2 vacuum pipe.
9. INSTALL THROTTLE BODY BRACKET.
- Install the throttle body bracket with the 4 nuts.

Torque: 21 N.m (210 kgf.cm, 15 ft.lb.)

10. CONNECT EGR GAS TEMPERATURE SENSOR CONNECTOR.
11. INSTALL EGR PIPE.
- Temporarily install the union nut of the EGR pipe.
- Install a new gasket and the EGR pipe with the 2 bolts.

Torque: 27 N.m (280 kgf.cm, 20 ft.lb.)

- Tighten the union nut of the EGR pipe.

Torque: 64 N.m (650 kgf.cm, 47 ft.lb.)

12. INSTALL INTAKE AIR CONNECTOR PIPE AND CONNECT CONTROL CABLES.

13. FILL WITH ENGINE COOLANT.
14. CHECK FOR FUEL LEAKS.
