Removal And Installation: Installation

WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

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.
1. Stage 1 : 5 - 10 N.m (0.5 - 1.0 kg-m, 44 - 86 in-lb)
2. Stage 2 : 26 - 31 N.m (2.7 - 3.2 kg-m, 20 - 23 ft-lb)

Seat the fuel injectors into the intake manifold with new O-rings. Tighten the fuel rail bolts as shown, in two stages:
1. Stage 1 : 9.3 - 10.8 N.m (0.95 - 1.1 kg-m, 83 - 95 in-lb)
2. Stage 2 : 21 - 26 N.m (2.1 - 2.7 kg-m, 15 - 20 ft-lb)

NOTE: After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:

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 .
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.
