Reposition hose clamp (7) and hose clamp (10) in
order to allow removal of hose (8). Disconnect
hose (8) from exhaust cooler assembly (2).
4.
Loosen V-band clamp (9) and position the clamp
away from the Exhaust Gas Recirculation (EGR)
valve assembly (1).
5.
Remove bolts (5) from exhaust cooler assembly
(2).
Note:
If studs are installed, it will be necessary to
remove the studs.
6.
Remove exhaust cooler assembly (2) from the
induction manifold.
7.
Remove gasket (6).

assembly.
Installation Procedure
1.
Check all components for wear and damage. If
necessary, replace any components that are worn
or damaged.
Note:
Remove plugs and caps that were previously
installed prior to assembly.

2.
Ensure that the NRS exhaust cooler is free from
restriction and external damage. Ensure that the
NRS exhaust cooler and tube assemblies are free
from wear and damage. Refer to Systems
Operation Testing and Adjusting, “Exhaust Cooler
(NRS) - Test” for the correct inspection procedure.
Note: The NRS exhaust cooler should not be
internally cleaned.
3.
Check that the sealing face on the EGR valve
assembly (1) and the diffuser is clean and free
from damage.
4.
Install a new clamp (9) to NRS mixer chamber (1).
Note:
Ensure that the clamp is correctly orientated to
prevent contact with any other engine components.
5.
Position a new gasket (6) onto the induction
manifold.
6.
Position exhaust cooler assembly (2) onto the
induction manifold. Install bolts (5) finger tight. If
studs were installed instead of bolts, install the
studs. Tighten the studs to a torque of 10 N·m
(89 lb in)
Note:
Ensure that the exhaust cooler assembly (2)
can still move freely.
7.
Tighten clamp (9) to a torque of 10 N·m (89 lb in)
8.
Tighten bolts (5) to a torque of 25 N·m (221 lb in)
