IMPORTANT: ALWAYS maintain coolant at correct
level and concentration. DO NOT
operate engine without coolant even
for a few minutes.
If frequent coolant makeup is
required, the glycol concentration
should be checked with JTO7298
Coolant/Battery Tester to ensure that
the desired freeze point is
maintained. Follow manufacturer’s
instructions provided with
Coolant/Battery Tester.
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 for
proper mixing of coolant ingredients before adding to
the cooling system.

Testing Diesel Engine Coolant
Testing Diesel Engine Coolant
Maintaining adequate concentrations of glycol and
inhibiting additives in the coolant is critical to protect
the engine and cooling system against freezing,
corrosion, and cylinder liner erosion and pitting.
Test the coolant solution at intervals of 12 months or
less and whenever excessive coolant is lost through
leaks or overheating.
Coolant test strips
Coolant test strips are available from your John Deere
dealer. These test strips provide a simple, effective
method to check the freeze point and additive levels of
your engine coolant.
Compare the results to the supplemental coolant
additive (SCA) chart to determine the amount of
inhibiting additives in your coolant and whether more
John Deere COOLANT CONDITIONER should be
added.
