5.

Apply anti-seize compound to the threads of the
EBP sensor tube fitting.

6.

Install EBP sensor tube to exhaust manifold and
tighten fitting to the special torque (Table 8).

Exhaust tube bolts (upper right)

7.

Apply anti-seize compound to the threads of two
M8 x 30 bolts and prevailing torque nuts.

8.

Install a new exhaust tube gasket and secure
the shielded tube exhaust assembly (upper right
side) to the right exhaust tube assembly. Loosely
assemble bolts and nuts.

exhaust assembly on left exhaust manifold

9.

Apply anti-seize compound to two M8 x 60 bolts
securing the shielded tube exhaust assembly to
the exhaust manifold flange. Loosely assemble
bolts and nuts.

10. For VGT installation procedure, see (Installation,

page 67).

11. After VGT installation, torque all bolts for VGT

tubing in the following order:

a.

Shielded exhaust tube assembly at right
exhaust tube (upper flange)

b.

Turbocharger exhaust adapter V-clamp

c.

EGR cooler V-clamp

d.

Shielded exhaust tube assembly at left
manifold

e.

Exhaust tube assembly at right manifold

See (Table 8) for special torque specifications.

Install a large O-ring on the EGR valve.

2.

Lubricate two new valve group O-rings with
a solution of dish washing soap and water
(approximately 50/50 mix) and install O-rings on
EGR valve.

Figure 129 Seat EGR valve

3.

When installing the EGR valve into the intake
manifold, make sure the valve is completely
seated by hand before installing bolts.

NOTE: Failing to completely seat the EGR valve
into the intake manifold, before inserting the
mounting bolts, may cause damage to the EGR
valve.

4.

Thread two M6 x 35 bolts by hand and tighten,
alternating between both bolts to the standard
torque (Standard Torques, page 375).

5.

Connect 8-pin electrical connector to EGR valve.

6.

Reinstall all safety guards, shields, and covers.

7.

Make sure all tools, cleanliness covers, loose
parts, and service equipment are removed from
the engine work area.
