Evans Cooling Systems announced an important milestone that demonstrates the durability and long life performance of its waterless engine coolant. Joe Umstead, an independent owner operator, has put a million miles on the 1990 Freightliner that he bought new. At the time of purchase, he converted its Detroit Diesel Series 60 engine to using an experimental waterless coolant provided by Evans. Twenty three years and a million miles later, Joe has never changed or topped off his coolant, or used any supplemental coolant additives.
