Engine cooling system
Organicid Acid Technology (OAT) coolant
CASE CONSTRUCTION requires the use of a fully formulated Organic Acid Technology (OAT) based coolant.
CASE
AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT
is preferred. The coolant must meet the specifications
outlined in the CNH Industrial material specification
MAT3624
. Use of coolant not meeting this specification is not
allowed. Mixing of different coolant brands is not recommended.
NOTICE:
OAT coolant is mandatory for all FPT engines compliant to TIER4B emissions using Selective Catalytic
Reduction (SCR). NEVER mix OAT coolant with conventional coolant. Under no circumstances should you top off a
cooling system with only water. You can use a refractometer to check the concentration level. You should not use
Supplemental Coolant Additives (SCA) when using
CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT
.
Change the coolant solution at the recommended change interval.
NOTE:
mix the
CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT
with 50% of clean water. Water for
dilution of OAT coolant concentrate: distilled or demineralized. If demineralized water is not available, use water for
dilution with the following properties:
Property
Maximum limit
Total Solids
340 ppm
Total Hardness
170 ppm
Chloride (Cl)
40 ppm
Sulfate (SO4)
100 ppm
Acidity pH
5.5 to 9.0
This solution ensures protection of the circuit from
-40.0 °C
(
-40.0 °F
) to
125.0 °C
(
257.0 °F
).
The optimum coolant/water concentration is 50/50. This concentration will protect the cooling system to
-37 °C
(
-35 °F
).If a premixed coolant is not available, mix the concentrate with 50 % of water. The coolant concentration in
the coolant/water mixture can be determined with a refractometer designed to measure ethylene glycol content.
Distilled water or deionized water is recommended for the use in the engine cooling systems.
DO NOT use hard water, sea water and, softened water sea that has been conditioned with salt. The minerals and
salts present in potable water can cause corrosion and deposits resulting in shortened engine life.
In the case that the customer may have topped off an OAT coolant system with conventional coolant, follow the “Wash-
ing of the cooling system” on the next page to attain the full benefit of the coolant.
