shall be used for the replacement of engine coolant according to the main-
tenance program of the machine. The replacement shall also be tackled in case of repair or replacement of compo-
nents of the cooling system. Refer to the dedicated procedure described in Chapter 6.
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.

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 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
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.
