3. If chlorides, sulfates or total dissolved solids are
higher than the above given specification, the water
must be distilled, demineralized, or deionized before
it is used in a cooling system.
4. If total hardness is higher than 170 ppm and all other
parameters are within the given specifications, the
water must be softened before it is used to make
coolant solution.
EGC: ETHYLENE GLYCOL CONCENTRATE
(ANTIFREEZE)
CAUTION:
EGC (Antifreeze) is flammable.
Keep it away from any open flame. Avoid contact
with eyes. Avoid contact with skin. Do not take inter-
nally. In case of contact, immediately wash skin with
soap and water. For eyes, flush with large amounts
of water for at least 15 minutes. Call a physician.
KEEP OUT OF REACH OF CHILDREN.
Follow all
warnings on the container.
1. Ethylene glycol coolant concentrate is commonly
mixed with water to produce an engine coolant with
a low freeze point and high boiling point.
2. A
low silicate
form of ethylene glycol coolant is
recommended for all diesel engines.
3. Use an ethylene glycol coolant concentrate
meeting ASTM D 4985P, SAEJ1941, General
Motors Performance Specification GM1899M,
or formulated to GM6038M.
4. This product is concentrated and should be mixed
to the following specification.
5. If additional coolant solution needs to be added
to the engine due to leaks or loss, the glycol
concentration should be checked with a hydrometer
to assure that the desired freeze point is maintained.
IMPORTANT
1. DO NOT use methyl alcohol or methoxy propanol
base EGC. These concentrates are not compatible with
chemicals used in supplemental coolant additives.
Damage can occur to rubber seals on cylinder liners
which are in contact with coolant.
2. DO NOT use an EGC containing sealer or stop-leak
additives.
3. DO NOT use EGC containing more than 0.1% anhy-
drous metasilicate. This type of concentrate, which is
intended for use in aluminum engines, may cause a
gel-like deposit to form that reduces heat transfer and
coolant flow. Check container label or consult with
supplier.
SUPPLEMENTAL COOLANT ADDITIVE (SCA)
CAUTION: Supplemental coolant additive con-
tains alkali. Avoid contact with eyes. Avoid contact
with skin. Do not take internally. In case of contact
immediately wash skin with soap and water. For
eyes, flush with large amounts of water for at least
15 minutes. Call a physician. KEEP OUT OF REACH
OF CHILDREN. Follow all warnings on the container.
1.
Important heat exchanger cooled engines
Additional SCA's should NOT be added to the mixture
of EGC/H
2
0 on initial fill up of engines with a coolant
conditioner-filter. A high SCA concentration will result
and can cause silicate-dropout. When this happens, a
gel-type deposit is created in the cooling system which
retards heat transfer and coolant flow.
2. If additional SCA's are needed, prepare a mixture
of 50% quality water and 50%EGC (antifreeze).
Add liquid SCA at a rate of 3%, by volume.
Example: 30 mL of SCA per liter of H
2
O/EGC
mixture (1.0 fl oz of SCA per qt of H
2
O/EGC).
Add the resulting mixture to the cooling system in
quart increments. Run the engine for 2 hours and retest
the coolant. Continue process until SCA concentration
meets recommended levels.
3. SCA is available from your Northern Lights dealer in
the following sizes.
Pint - Part Number...............20-00002
1/2 gallon - Part Number.....20-00003
4. DO NOT use any coolant system additives
