4. MAINTENANCE
IMPORTANT: When adding coolant to the system,
use the appropriate coolant solution. Coolant 50/50
mixture of antifreeze/distilled water meeting ASTM
4985, ASTM D5345 (pre-diluted coolant) or John
Deere COOL-GARD. 50/50 mixture provides
protection to -34° F (-37° C). Do not overfill cooling
system. A pressurized system needs space for heat
expansion without overflowing at top of radiator.
2. Fill until coolant level touches bottom of
radiator filler neck.
3. Tighten fitting when air has been expelled from
system.
4.8.3 Disposing of Coolant
Improperly disposing of engine coolant can threaten
the environment and ecology.
Use leakproof containers when draining fluids. Do not
use food or beverage containers that may mislead
someone into drinking from them.
Do not pour waste onto the ground, down a drain, or
into any water source.
Inquire on the proper way to recycle or dispose of
waste from your local environmental or recycling
center or from your dealer.
