Diesel Engine Coolant (engine with wet sleeve cylinder liners)
Failure to follow applicable coolant standards and drain
intervals can result in severe engine damage that may
not be covered under warranty. Warranties, including the
emissions warranty, are not conditioned on the use of
John Deere coolants, parts, or service.
Preferred Coolants
The following pre-mix engine coolants are preferred:
•
John Deere COOL-GARD
™
II
•
John Deere COOL-GARD II PG
COOL-GARD II pre-mix coolant is available in several
concentrations with different freeze protection limits as
shown in the following table.
COOL-GARD II Pre-Mix
Freeze Protection Limit
COOL-GARD II 20/80
-9°C (16°F)
COOL-GARD II 30/70
-16°C (3°F)
COOL-GARD II 50/50
-37°C (-34°F)
COOL-GARD II 55/45
-45°C (-49°F)
COOL-GARD II PG 60/40
-49°C (-56°F)
COOL-GARD II 60/40
-52°C (-62°F)
Not all COOL-GARD II pre-mix products are available in
all countries.
Use COOL-GARD II PG when a non-toxic coolant
formulation is required.
Additional Recommended Coolants
The following engine coolant is also recommended:
•
John Deere COOL-GARD II Concentrate in a 40—60%
mixture of concentrate with quality water.
IMPORTANT: When mixing coolant concentrate with
water, do not use less than 40% or greater
than 60% concentration of coolant. Less than
40% gives inadequate additives for corrosion
protection. Greater than 60% can result in
coolant gelation and cooling system problems.
Other Coolants
Other ethylene glycol or propylene glycol base coolants
may be used if they meet the following specification:
•
Pre-mix coolant meeting ASTM D6210 requirements
•
Is formulated with a 2-ethylhexanoic acid (2-EHA) free
additive package
•
Coolant concentrate meeting ASTM D6210
requirements in a 40—60% mixture of concentrate with
quality water
If coolant meeting one of these specifications is
unavailable, use a coolant concentrate or pre-mix coolant
that has a minimum of the following chemical and physical
properties:
•
Provides cylinder liner cavitation protection according to
either the John Deere Cavitation Test Method or a fleet
study run at or above 60% load capacity
•
Is formulated with a nitrite-free additive package
•
Is formulated with a 2-ethylhexanoic acid (2-EHA) free
additive package
•
Protects the cooling system metals (cast iron, aluminum
alloys, and copper alloys such as brass) from corrosion
Water Quality
Water quality is important to the performance of the
cooling system. Deionized or demineralized water
is recommended for mixing with ethylene glycol and
propylene glycol base engine coolant concentrate.
Coolant Drain Intervals
Drain and flush the cooling system and refill with fresh
coolant at the indicated interval, which varies with the
coolant used.
When COOL-GARD II or COOL-GARD II PG is used, the
drain interval is 6 years or 6000 hours of operation.
If a coolant other than COOL-GARD II or COOL-GARD II
PG is used, reduce the drain interval to 2 years or 2000
hours of operation.

IMPORTANT: Do not use cooling system sealing
additives or antifreeze that contains
sealing additives.
Do not mix ethylene glycol and propylene
glycol base coolants.
Do not use coolants that contain nitrites.

Coolant analysis may extend the service interval of other "Coolants"
to a maximum not to exceed the interval of Cool-Gard II coolants.
Coolant analysis means taking a series of coolant samples at 1000
hour increments beyond the normal service interval until either
the data indicate the end of useful coolant life or the maximum
service interval of Cool-Gard II is reached.
