6. Disconnect EGR volume control valve water hoses and wiring harness.
7. Disconnect heater hose.
8. Remove EGR Cooler.
9. Remove injection tube center. Refer to EM-157, "
Removal and Installation" .
CAUTION:
Be careful not to spill fuel in the engine component.
10. Remove water pipe.
11. Remove fuel hoses and fuel gallery.

To prevent fuel from flowing out, plug the opening of the hose with plug after disconnection.
CAUTION:
Be careful not to spill fuel in the engine component.
12. Loosen bolts and nuts in reverse order of that shown in the fig-
ure, and remove intake manifold.
CAUTION:
Cover engine openings to avoid entry of foreign materials.
13. Remove EGR volume control valve from intake manifold.
INSPECTION AFTER REMOVAL
Surface Distortion

Check distortion on the mounting surface with a straightedge
and feeler gauge.

If it exceeds the limit, replace intake manifold.
INSTALLATION
Following instructions below, install in the reverse order of removal.
1. Install EGR volume control valve.

Handle with care avoiding any shocks.

Do not disassemble.
2. Install intake manifold.

Tighten fixing bolts and nuts in numerical order as shown in the figure.

When stud bolts come off, install with the following torque.
PBIC0676E
Limit : 0.1 mm (0.004 in)
PBIC0677E
: 10 - 11 N·m (1.0 - 1.2 kg-m, 87 - 104 in-lb)
