1. Remove the core. Refer to the Service Manual
for the procedure.
2. Turn the aftercooler core upside-down in order
to remove debris.
NOTICE
Do not use a high concentration of caustic cleaner to
clean the core. A high concentration of caustic cleaner
can attack the internal metals of the core and cause
leakage. Only use the recommended concentration of
cleaner.
3. Back flush the core with cleaner.
Caterpillar recommends the use of hot Hydrosolv
100 liquid cleaner at a concentration of 30% and
at a temperature of 66
to 82
C (150
to 180
F).
Table 35 lists the recommended Hydrosolv liquid
