COOLANT
(ANTIFREEZE/SUMMER COOLANT/WATER)
John Deere recommends Cool-Gard II
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.
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.
Day-to-day addition of coolant is done from the reserve
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 reserve tank coolant
capacities.

NOTICE
Normally, only the coolant level in the reserve tank
needs to be checked. However, the radiator cap should
be opened once a week to verify that coolant is visible
(full) inside the radiator.
Verify that the coolant level in the coolant reserve tank
is between the FULL and LOW markings as shown in
Figure 46.

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.
