NOTE: The two hoses that have been removed from the CVT fluid warmer will be used to flush the radiator
based cooler; first in one direction and then the other.
CAUTION:
 Wear safety glasses and rubber gloves when
spraying the Transmission Cooler Cleaner.
 Spray Cooler Cleaner only in areas with
adequate ventilation.
 Avoid contact with eyes and skin.
 Do not breathe vapors or mist from spray.
8. Insert the “extension adapter hose”, from a can of
Cooler Cleaner (Nissan P/N 999MP-AM006P), into
one or the other of the disconnected CVT fluid
cooler hoses (Figure 3E).
