(1) If the engine has been exposed to fire extinguishing agents on its internal surfaces, perform
the following:
(a) Carbon dioxide (CO2) contamination.
1) Remove the engine for disassembly and cleaning (TASK 71-00-02-004-004-G00).
(b) Chemical foam contamination.
1) Dry motor the engine and flush with clean water to remove the foam residues
