Engine coolant
CASE CONSTRUCTION requires the use of a fully formulated Organic Acid Technology (OAT) based coolant. CASE
AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT is the reference genuine product.
NOTICE: Use of different coolant brands is not recommended.
NOTICE: Never add Supplemental Coolant Additives (SCA) when using CASE AKCELA ACTIFULL™ OT
EXTENDED LIFE COOLANT.
NOTICE: Never mix CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT coolant with conventional
coolant. Mixing OAT based coolant with conventional coolant will reduce the effectiveness of OAT coolant.
NOTICE: If only conventional coolant is available, a complete changeover of the fluid into the cooling system shall be
carried out.
The engine cooling system shall always be refilled with coolant solution made by mixture of antifreeze and distilled
(deionized) water.
NOTICE: Never refill the cooling system with only antifreeze. Never refill the cooling system with only water.
Using CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT, a 50/50 mixture of antifreeze and distilled
(deionized) water grants proper performance of the engine cooling system in the above mentioned operating temper-
ature range of the machine.
CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT is available as:
• 50/50 PREMIXED coolant solution ready for usage.
• CONCENTRATE antifreeze to be mixed 50/50 with distilled (deionized) water.
NOTICE: If operating in extreme winter climate, a coolant solution made by 60/40 antifreeze/distilled (deionized) water
mixture shall be used in order to grant proper performance of the engine cooling system.
NOTICE: Never use coolant solution with more than 60% of antifreeze. This affects the cooling capacity of the mixture.
When the coolant solution is prepared starting from the CONCENTRATE product, the antifreeze concentration in the
mixture of antifreeze and distilled (deionized) water can be determined with a refractometer designed to measure
ethylene glycol content.
If distilled (deionized) water is not available, use water for dilution with the following properties:
Property
Total Solids
Total Hardness
Chloride (Cl)
Sulfate (SO4)
Acidity pH
NOTICE: Never use hard water, sea water and softened sea water that has been conditioned with salt. The minerals
and salts present in potable water can cause corrosion and deposits resulting in shortened engine life.
