6. Inspect the valve assembly for damage and
test as required. Replace the assembly if
necessary.
INSTALLATION PROCEDURE
1. Carefully clean and inspect the mounting
flange of the EGR gas hot tube.
Use care when cleaning component parts of the
EGR system. Dirt and debris entering the system
could cause blockage within the cooler core or
EGR valve.
2. Clean and inspect the valve mounting
surface of the exhaust manifold and the tube
flange and mounting base of the valve
assembly. Again, use care to avoid getting
dirt and debris in the system.
A metal gasket, shown in Figure 501, is used
between the mounting base of the EGR valve
assembly and the exhaust manifold. Make sure
that it is installed.

3. Install a new gasket on the EGR valve
assembly mounting surface of the exhaust
manifold (Figure 502).

4. Place the valve assembly in position on the
exhaust manifold studs (Figure 503).
Loosely install the retaining nuts. DO NOT
tighten them at this time. This allows the
EGR valve to “float” into the best alignment
position.
