COOLANT (ANTIFREEZE/SUMMER COOLANT/
WATER)
John Deere recommends Cool-Gard II
TM
antifreeze/summer
coolant for use in their engines, which can be purchased in
concentrate (and mixed with 50% demineralized water) or
pre-diluted. See the
John Deere Engine Owner’s Manual
for further details.
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 11 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 in Freezing Weather
When operating in freezing weather, be certain the proper
amount of antifreeze (Table 12) has been added.
WARNING
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.

NOTICE
When the antifreeze is mixed with water, the antifreeze
mixing ratio
must be less than 50%.
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
air cleaner in accordance with the
John Deere 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
John
Engine Owner’s Manual.
The fan belt tension is proper if the fan belt bends 10 to 15
mm (Figure 38) when depressed with the thumb as shown
below.

CAUTION
NEVER place hands near the belts or fan
while the generator set is running.
