IMPORTANT: Do not add supplemental coolant
additives when the cooling system is
drained and refilled with John Deere
COOL-GARD
NOTE: If system is to be filled with coolant that does
not contain SCAs, the coolant must be
precharged. Determine the total system
capacity and premix with 3% John Deere
Coolant Conditioner.
Through time and use, the concentration of coolant
additives is gradually depleted during engine operation.
Periodic replenishment of inhibitors is required, even
when John Deere COOL-GARD
is used. The cooling
system must be recharged with additional
supplemental coolant additives available in the form of
liquid coolant conditioner.
Maintaining the correct coolant conditioner
concentration (SCAs) and freeze point is essential in
your cooling system to protect against rust, liner pitting
and corrosion, and freeze-ups due to incorrect coolant
dilution.
John Deere LIQUID COOLANT CONDITIONER is
recommended as a supplemental coolant additive
in John Deere engines.
DO NOT mix one brand of SCA with a different
brand.
Test the coolant solution every 500 hours or 12
months of operation using either John Deere coolant
test strips or a COOLSCAN
analysis. If a
COOLSCAN
analysis is not available, recharge the
system per instructions printed on label of John Deere
Liquid Coolant Conditioner.
