Rework Procedure


 
Drain the coolant as required and then remove the sea water and engine coolant tubes from the backside of the front mounted heat exchanger. Inspect the liners and collars for damage. If the liners and collars need replaced, refer to the removal and installation procedure described in Special Instruction REHS2599 (Cleaning the Engine Mounted Heat Exchanger).

After damaged liners and collars have been replaced, replace the engine coolant tubes with new tubes and install one spacer between the heat exchanger and each sea water tube.

NOTE: Certain engines were shipped with washers between the heat exchanger and the sea water tubes to keep the tubes from damaging the liners. The liners and collars on these engines will not need to be replaced. The washers should be discarded when the new tubes and spacers are installed.
