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 at 500 hours or 12 months of
operation using either John Deere coolant test strips or a
COOLSCAN

or COOLSCAN PLUS

analysis. If a
COOLSCAN

or COOLSCAN PLUS

analysis is not
available, recharge the system per instructions printed on
label of John Deere Liquid Coolant Conditioner.
