Problems with the cooling system cause 40% of premature engine failures. Caterpillar offers extended life coolant which protects highperforming equipment and helps support customers' investments.
THERE ARE TWO TYPES OF EXTENDED LIFE COOLANT:
CAT ELC
- Contains Glycol
CAT ELI
- Water-based coolant that does not contain Glycol
This coolant uses Organic Acid Technology (OAT) with additives extending the life of the coolant without the need for supplemental coolant additive (SCA).
Cat DEACTM and Cat NGECTM offer conventional coolant-proven technology which is an option for customers looking for lower upfront costs.
