Preferred - Caterpillar Extended Life Coolant (ELC) or a commercial ELC that meets the Caterpillar specification (EC-1)
Acceptable - A Caterpillar Diesel Engine Antifreeze/Coolant (DEAC) or a commercial heavy-duty coolant/antifreeze that meets "ASTM D4985" or "ASTM D5345" specifications
| NOTICE |
|---|
Do not use a commercial coolant/antifreeze that only meets the "ASTM D3306" specification. This type of coolant/antifreeze is made for light duty automotive applications. |
CLAAS recommends a 1:1 mixture of water and glycol. This mixture of water and glycol will provide optimum heavy-duty performance as a coolant/antifreeze.
Note: Caterpillar DEAC does not require a treatment with an SCA at the initial fill. However, a commercial heavy-duty coolant/antifreeze that meets "ASTM D4985" or "ASTM D5345" specifications requires a treatment with an SCA at the initial fill.
