7. Maintenance
7.1.3 Coolant
The engine cooling system is fuelled with OAT: ENI ANTIFREEZE SPEZIAL coolant, mixed at 50% with dem
-
ineralised water.
It is recommended to continue using the same coolant.
If the type of coolant is changed for refuelling, the system must be thoroughly washed.
By mixing with each other, the residues of additives of different types contained in the different liquids would
create gelatinous substances that could obstruct the system.
Use a mixture of 50% demineralised water and 50% low silicate ethylene glycol coolant.
Use a coolant free from silicates, phosphates, borates, nitrites and amines.
The following ethylene glycol based engine coolants may be used:
- low silicate OAT (Organic Acid Technology): ASTM D-3306 D-6210
- low silicate HOAT (Hybrid Organic Acid Technology): ASTM D-3306 D-6210
*
Important
• Do not mix OAT and HOAT coolants.
• Never use automotive coolants. These coolants do not contain the correct additives to protect
heavy-duty diesel engines.
Oat coolants are maintenance-free for up to 6 years or 6000 operating hours, provided that the cooling sys-
tem is topped up using the same type of coolant.
Do not mix different types of coolant.
Test the coolant condition annually with coolant test strips.
HOATs are not all maintenance-free and it is recommended to add SCA (Supplemental Coolant Additives) at
the first maintenance interval.
Refuelling
WARNING
•
Before refuelling, read
“2.9 Maintenance precautions”carefully.
Check the coolant level when the engine is cold.
1 - Open the radiator cap access door (1).
