provides freezing and boiling point
protection.
WARNING!
Coolant is toxic. DO NOT get the fluid in
eyes. If contact occurs, flood eyes with large
amounts of water for 15 minutes. Avoid pro-
longed or repeated contact with skin. In
case of contact, immediately wash skin with
soap and water. DO NOT take internally. If
swallowed, seek immediate medical atten-
tion. DO NOT induce vomiting. Failure to
comply may result in death, personal injury,
equipment or property damage.
CAUTION
The engine cooling system has very specific
maintenance and inspection requirements.
Failure to follow requirements can damage
the engine. Engine damage can include but
is not limited to freezing, boiling, corrosion,
pitted cylinder liners. This information is
found in the engine manufacturers owner’s
manual. It is the owner’s responsibility to fol-
low all requirements listed in the engine
manufacturers owner’s manual.
NOTE
Coolant is harmful to the environment. Un-
used coolant must be stored as a toxic haz-
ardous material in leakproof containers.
Used coolant must be processed as indus-
trial chemical waste. Please follow HAZMAT
guidelines with both used and unused cool-
ants.
Concentration
Check the level of freeze/boilover
protection, which is determined by the ELC
concentration. Use a glycol refractometer
to determine glycol level. Add ELC to
obtain the ELC/water ratio required to
provide the protection you need. A 50/50
mix of ELC and water is adequate for most
applications. For extremely cold operating
conditions, the ratio can be adjusted to a
higher concentration of ELC.
In an ELC-filled cooling system, the freeze
point should be maintained between -30° F
and -45° F (-34° C and -43° C).
NOTE
Maximum recommended ELC concentration
is 60% ELC and 40% water by volume (a
60/40 coolant mixture). The minimum rec-
ommended concentration is 40%.
Condition
Perform a visual inspection of the ELC. It
should have no cloudiness or floating
debris. Determine the chemical inhibitor
concentration level by using an ELC-
specific test kit or test strips. Inhibitor
concentration level determines corrosion
protection. If you are concerned about
possible coolant quality, contamination, or
mechanical problems, submit a coolant
sample for analysis. Improper maintenance
may cause coolant degradation and could
result in damage to the cooling system and
engine components. Consult your dealer or
the ELC manufacturer’s representative for
recommended ELC test kits, test strips,
and laboratory sample procedures.
