(e) f the tubes are so dogged that a
rod can not be passed thru them,
the core will have to be removed
from its casing and boiled in a
caustic soda solution. Commercial
cooling system cleaners can be
used for this purpose. Reassem-
ble with new gaskets, seals, and
'O" rings.
(f) I a reduced power and/or exces-
sive smoke condition exists in
addition to an increase in coolant
temperature with a turbocharged
engine having an air charge cooler
(intercooler), check the intercooler
and, if necessary, clean as
described for heat exchangers.
(g) Check the exhaust manifold outlet
elbows and the exhaust water
injection connections for mud or
silt, especially if the engine was
operated in muddy or silty water.
(h) Oil Coolers - both engine and
gear box - can also affect engine
coolant temperatures. Oil coolers
should be checked and cleaned as
described for heat exchangers.
4) Reconnect heat exchanger and
reactivate. Check for leaks.
d. Remove red tag from switchboard
