Antifreeze Recommendations
The following coolant is preferred for use:
• John Deere COOL-GARD Prediluted
Coolant.
OR
• John Deere COOL-GARD Coolant
Concentrate in a 40 to 60% mixture of
concentrate with quality water.
Other low silicate ethylene glycol base
coolants for heavy-duty engines may be used
if they meet one of the following specifications:
• ASTM D5345 (prediluted coolant)
OR
• ASTM D4985 (coolant concentrate) in a 40
or 60% mixture of concentrate with quality
water.
Note that water quality is important. Distilled,
deionized, or demineralized water is
recommended for mixing with ethylene glycol
based engine coolant concentrate.
Coolants meeting these specifications require
the use of supplemental coolant additives,
formulated for heavy-duty diesel engines, for
protection against corrosion and cylinder liner
erosion and pitting.
A 50% mixture of ethylene glycol engine
coolant in water provides freeze protection to
-37ºC (-34ºF). If protection at lower
temperatures is required, contact your
AMADAS/John Deere dealer for
recommendations.
