Coolant (Ethylane Glycol [Green] / Water — 50/50 mix)
Use only drinkable tap water. If hard water or water with
many impurities is used, the inside of the engine and radiator
may become coated with deposits and cooling efficiency
will be reduced.
An anticorrosion additive added to the water will help prevent
deposits and corrosion in the cooling system. See the engine
manual for further details.

CAUTION:
If adding coolant/antifreeze
mix to the radiator,
DO
NOT
remove the radiator
cap until the unit has completely cooled. The
possibility of
hot!
coolant exists which can cause severe
burns.
Day-to-day addition of coolant is done from the recovery
tank. When adding coolant to the radiator,
DO NOT
remove
the radiator cap until the unit has completely cooled. See
Table 12 for engine, radiator, and recovery tank coolant
capacities. Make sure the coolant level in the recovery tank
is always between the "
H
" and the "
L
" markings.
Operation Freezing Weather
When operating in freezing weather, be certain the proper
amount of antifreeze (Table 13) has been added.

:
Cleaning the Radiator
The engine may overheat if the radiator fins become
overloaded with dust or debris. Periodically clean the radiator
fins with compressed air. Cleaning inside the machine is
dangerous, so clean only with the engine turned off and the
negative
battery terminal disconnected.
Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the
Isusu Engine Owner's Manual.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the
Isuzu
Engine Owner's Manual.
The fan belt tension is proper if the fan belt bends 10 to 15
mm (Figure 42) when depressed with the thumb as shown
below.

DCA-45SSIU2 — PRE-SETUP
When the antifreeze is mixed with
water, the antifreeze mixing ratio
must be
less than 50%.
NOTE
NEVER!
place hands near
the belts or fan while the
generator set is running.
