2. Install Intake Manifold Pressure Test Plug (Table
9) in EGR orifice.
3. Install Intake Manifold Pressure Test Cap(Table 9)
on air intake.
WARNING: To prevent personal injury or
death, wear safety glasses with side shields to
protect eyes. Limit compressed air pressure to
207 kPa (30 psi).
4. Submerge intake manifold assembly in water.
5. Use a regulated filtered air supply and pressurize
to 172 to 207 kPa (25 to 30 psi). Inspect for leaks
in the intake plenum, EGR, and coolant passages.
Replace intake manifold, if necessary.
6. Inspect intake manifold gasket seal beads for
defects. Replace gasket, if necessary.
Read all safety instructions in the "Safety Information" section of this manual before doing any procedures.
