5-13
5.6.13 Clean outside of Radiator and Oil Cooler
Every 1,000 hours
When the fin tubes“1”of a radiator and an oil cooler are
clogged with dust or other foreign materials, the heat
exchange efficiency drops and this will raise coolant
temperature and discharge air temperature. These tubes and
fins should be cleaned depending on the state of clogged fin
tubes “1”even before 1,000 hours maintenance schedule.
Do not use a high pressure washer to protect fin tubes from
being damaged.
5.6.14 Clean inside of Radiator
Every 1,000 hours
When the inside of a radiator and water conduits of an engine are dirty with scale and rust, its
cooling efficiency will be deteriorated. Clean the interiors of such components periodically.
Ask your nearest dealer for such inner cleaning.
