Cool-Gard™ Ii Coolant Extender; Testing Diesel Engine Coolant; Disposing Of Coolant - Worldwide Construction And Forestry Division 380GLC Operator's Manual

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.
When Using John Deere COOL-GARD II
John Deere COOL-GARD II Premix™ , COOL-GARD
II PG Premix and COOL-GARD II Concentrate are
maintenance free coolants for up to six years or 6000
hours of operation, provided that the cooling system is
topped off using only John Deere COOL-GARD II Premix
or COOL-GARD II PG premix. Test the coolant condition
annually with coolant test strips designed for use with
John Deere COOL-GARD II coolants. If the test strip
chart indicates that additive is required, add John Deere
COOL-GARD II Coolant Extender as directed.

Disposing of Coolant

Improperly disposing of engine coolant can threaten the
environment and ecology.
Use leakproof containers when draining fluids. Do not use
food or beverage containers that may mislead someone
into drinking from them.
Do not pour waste onto the ground, down a drain, or into
any water source.
Inquire on the proper way to recycle or dispose of waste
from a local environmental or recycling center, or from an
authorized John Deere dealer.
Maintenance—Machine
Add only the recommended concentration of John Deere
COOL-GARD II Coolant Extender. DO NOT add more
than the recommended amount.
When Using Nitrite-Containing Coolants
Compare the test strip results to the supplemental coolant
additive (SCA) chart to determine the amount of inhibiting
additives in your coolant and whether more John Deere
Liquid Coolant Conditioner should be added.
Add only the recommended concentration of John Deere
Liquid Coolant Conditioner. DO NOT add more than the
recommended amount.
Coolant Analysis
For a more thorough evaluation of your coolant, perform a
coolant analysis. The coolant analysis can provide critical
data such as freezing point, antifreeze level, pH, alkalinity,
nitrite content (cavitation control additive), molybdate
content (rust inhibitor additive), silicate content, corrosion
metals, and visual assessment.
Contact your John Deere dealer for more information on
coolant analysis.
