1Do not use a supplemental coolant additive element and a
liquid supplemental coolant additive at the same time. Do
not exceed the maximum concentration of six percent.
Check the concentration with a supplemental coolant
additive test kit.
Permitted-Water/Supplemental Coolant Additive
Never use water alone without supplemental coolant
additive or inhibited coolant. Water alone is
corrosive at engine operating temperatures.
A mixture of water and supplemental coolant
additive does not protect against freezing or boiling.
A coolant mixture of water and supplemental coolant
additive will cool and provide some protection to
engine components, but it will NOT provide normal
engine service life.
Caterpillar's recommendation for proper coolant is a
minimum concentration of 30 percent glycol and 70
percent acceptable water and supplemental coolant
additive (three percent of the total mixture). This
In applications where freeze protection is not required, or
where antifreeze is not available, a coolant mixture of
acceptable water and supplemental coolant additive can
be used. A water/supplemental coolant additive system
should maintain a six to eight percent supplemental
coolant additive concentration. DO NOT exceed eight
concentration levels must be monitored.
The 8T5296 Test Kit can be used to evaluate the
water/supplemental coolant additive coolant, with the
following modifications to label instruction Step 3 and
STEP 3. - Add tap water to the vial up to the 20 ml
STEP 5 -With the defined procedure, the six to eight
percent concentration will yield a 20 to 27 drop range.
supplemental coolant additive and more drops indicate a
If the supplemental coolant additive concentration is
greater than the maximum of eight percent: drain some
of the coolant, refill the system with acceptable water,
and retest the concentration level.
