water is recommended for mixing with ethylene glycol
and propylene glycol base engine coolant concentrate.
IMPORTANT: Do not use cooling system sealing
additives or antifreeze that contains
sealing additives.

Drain Intervals for Diesel Engine Coolant
Drain the factory fill engine coolant, flush the cooling
system, and refill with new coolant after the first 3 years
or 3000 hours of operation.
Subsequent drain intervals are determined by the coolant
used for service. At each interval, drain the coolant, flush
the cooling system, and refill with new coolant.
When John Deere COOL-GARD is used, the drain
interval may be extended to 5 years or 5000 hours of
operation, provided that the coolant is tested annually
AND additives are replenished, as needed, by adding a
supplemental coolant additive.
If John Deere COOL-GARD is used but the coolant is not
tested OR additives are not replenished by adding a
supplemental coolant additive, the drain interval is 3 years
or 3000 hours of operation
If COOL-GARD is not used, the drain interval is reduced
to 2 years or 2000 hours of operation.
