IMPORTANT: ALWAYS maintain coolant at correct
level and concentration. DO NOT
operate engine without coolant for
even a few minutes.
If frequent coolant makeup is
required, the glycol concentration
should be checked with JT07298
Coolant/Battery Tester to ensure that
the desired freeze point is
maintained. Follow manufacturer’s
instructions provided with
refractometer.
Add the manufacturer’s recommended concentration of
supplemental coolant additive. DO NOT add more than
the recommended amount.
The use of non-recommended supplemental coolant
additives may result in additive drop-out and gelation
of the coolant.
If other coolants are used, consult the coolant supplier
and follow the manufacturer’s recommendation for use
of supplemental coolant additives.
See DIESEL ENGINE COOLANTS AND
SUPPLEMENTAL ADDITIVE INFORMATION earlier in
this group for proper mixing of coolant ingredients
before adding to the cooling system.

Operating in Warm Temperature Climates
John Deere engines are designed to operate using glycol
base engine coolants.
Always use a recommended glycol base engine coolant,
even when operating in geographical areas where freeze
protection is not required.
IMPORTANT: Water may be used as coolant
in
emergency situations only.
Foaming, hot surface aluminum and
iron corrosion, scaling, and cavitation
will occur when water is used as the
coolant, even when coolant
conditioners are added.
Drain cooling system and refill with
recommended glycol base engine
coolant as soon as possible.
