What kind of coolant does a Cummins take?

Coolant Selection for 12v Cummins The Cummins 6BT requires a 50/50 mix of ethylene glycol based anti-freeze and water. We highly recommend a Fleetguard ELC (extended life coolant) for all Cummins diesels.

What antifreeze should I use in a diesel engine?

For diesel trucks using green antifreeze, the recommendation of coolant service is usually around two years or 30,000 miles. For diesel engines running extended-life coolant, service is around five years or 100,000 miles. To be on the safe side, periodically check the antifreeze every six months.

What happens if you put antifreeze in a diesel tank?
