Frequent question: 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.
