What Deere says about cooland
SPECIFICATIONS & INFORMATION COOLANT SPECIFICATIONS
John Deere Dealers: You may want to cross-reference the
following publications to recommend the proper oil for your
customers:
• Module DX,ENOIL2 in JDS–G135;
• Section 530, Lubricants & Hydraulics, of the John Deere
Merchandise Sales Guide;
• Lubrication Sales Manual PI7032.
Coolant Specifications
Engine Coolant
The engine cooling system, when filled with a proper
dilution mixture of anti-freeze and deionized or distilled
water, provides year-round protection against corrosion,
cylinder or liner pitting, and winter freeze protection down
to –37°C (–34°F).
The following John Deere coolant is PREFERRED:
• PRE-DILUTED DIESEL ENGINE ANTI-FREEZE/
SUMMER COOLANT™ (TY16036).
This coolant satisfies specifications for “Automobile and
Light Duty Engine Service” and is safe for use in John
Deere Lawn and Grounds Care/Golf and Turf Division
equipment, including aluminum block gasoline engines and
cooling systems.
The above preferred pre-diluted anti-freeze provides:
• adequate heat transfer
• corrosion-resistant chemicals for the cooling system
• compatibility with cooling system hose and seal material
• protection during extreme cold and extreme hot weather
operations
• chemically pure water for better service life
• compliance with ASTM D4656 (JDM H24C2)
specifications
If above preferred pre-diluted coolant is not available, the
following John Deere concentrate is recommended:
• DIESEL ENGINE ANTI-FREEZE/SUMMER COOLANT
CONCENTRATE™ (TY16034).
If either of above recommended engine coolants are not
available use any Automobile and Light Duty Engine
Service ethylene glycol base coolant, meeting the
following specification:
• ASTM D3306 (JDM H24C1).
Read container label completely before using and follow
instructions as stated.
Mix 50 percent anti-freeze concentrate with 50 percent
distilled or deionized water. This mixture and the prediluted
mixture (TY16036) will protect the cooling system down to
–37°C (–34°F) and up to 108°C (226°F).
Certain geographical areas may require lower air
temperature protection. See the label on your anti-freeze
container or consult your John Deere dealer to obtain the
latest information and recommendations.
Engine Coolant Drain Interval
When using John Deere Pre-Diluted (TY16036)
Automobile and Light Duty Engine Service coolants, drain
and flush the cooling system and refill with fresh coolant
mixture every 36 months or 3,000 hours of operation,
whichever comes first.
When using John Deere Concentrate (TY16034)
Automobile and Light Duty Engine Service coolants, drain
and flush the cooling system and refill with fresh coolant
mixture every 24 months or 2,000 hours of operation,
whichever comes first.
If above John Deere Automobile and Light Duty Engine
Service coolants are not being used, drain, flush, and refill
the cooling system according to instructions found on
product container or in equipment operator’s manual or
technical manual.
IMPORTANT: Avoid damage! To prevent engine
damage, DO NOT use pure anti-freeze or less
than a 50% anti-freeze mixture in the cooling
system.
DO NOT mix or add any additives/
conditioners to the cooling system in Lawn and
Grounds Care/Golf and Turf Division equipment.
Water used to dilute engine coolant concentrate
must be of high quality—clean, clear, potable
water (low in chloride and hardness—Table 1) is
generally acceptable.
DO NOT use salt water.
Deionized or distilled water is ideal to use.
Coolant that is not mixed to these specified levels
and water purity can cause excessive scale,
sludge deposits, and increased corrosion
potential.
Property Requirements
Total Solids, Maximum 340 ppm (20 grns/gal)
Total Hardness, Max. 170 ppm (10 grns/gal)
Chloride (as Cl), Max. 40 ppm (2.5 grns/gal)
Sulfate (as SO4), Max. 100 ppm (5.8 grns/gal)
Bear in mind that these are general recommendations and you should follow what is specifically spelled out in the particular Operator's Manual for your piece of equipment.
