Removal and Installation: Installation

Installation is in the reverse order of removal. Follow the procedures below for specific tightening sequences and procedures.

• Install intake manifold bolts in two stages in the numerical order as shown.

  Stage 1 :7.5 N.m (0.77 kg-m, 66 in-lb) 

  Stage 2: 28.5 N.m (2.9 kg-m, 21 ft-lb)

• Seat the fuel injectors into the intake manifold with new O-rings.

  Tighten the fuel rail bolts as shown, in two stages:

  CAUTION: Do not reuse O-rings.

• Tighten the bolts of the intake manifold collector (upper) and electric throttle control actuator assembly equally and diagonally to specification.

1. Perform the "Throttle Valve Closed Position Learning" when harness connector of the electric throttle control actuator is disconnected. Refer to "THROTTLE VALVE CLOSED POSITION LEARNING ".
2. Perform the "Idle Air Volume Learning" when the electric throttle control actuator is replaced. Refer to "IDLE AIR VOLUME LEARNING ".
   • Install the quick connector as follows:
     • Make sure no foreign substances are deposited in and around the fuel tube and quick connector and that there is no damage.
     • Align the center to insert the quick connector straight onto the fuel tube.
     • Insert the fuel tube until a click is heard.
     • Install the quick connector cap on the quick connector joint.

       Align the arrow mark on the quick connector cap to the upper side.

     • Install the fuel hose into the hose clamp.
