Evans Cooling Systems marks endurance milestone

摘要

A 1990 Freightliner running on waterless engine coolant from Evans Cooling Systems has traveled one million miles in 23 years without requiring a coolant change, coolant fill or the use of supplemental additives. Joe Umstead, an owner-operator, converted to the waterless coolant provided by Evans in the Detroit Diesel Series 60 engine when he purchased his new truck.
