Aftercooler Assembly (010-005)
Initial Check
A turbocharger or sea water pump failure can cause
damage to the aftercooler assembly.
If a turbocharger failure or a sea water pump failure has
occurred, remove the aftercooler element and inspect the
element and housing for damage.
Inspect the zinc anodes to make sure they are still in one
piece and have not broken.
See the Inspect step within this procedure.
