Engine coolant
CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT is the reference genuine product for machine service.
NOTICE: Never add Supplemental Coolant Additives (SCA) when using CASE AKCELA ACTIFULL™ OT
EXTENDED LIFE COOLANT.
CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT has to be used if refilling of the cooling system is
needed. Refer to the dedicated procedure and recommendations described in Chapter 6.
CASE AKCELA ACTIFULL™ OT EXTENDED LIFE COOLANT must be used for the replacement of engine coolant
according to the maintenance program of the machine. The replacement shall also be tackled in case of repair or
replacement of components of the cooling system. Refer to the dedicated procedure described in Chapter 6.
The engine cooling system should 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 must 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:

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.
