According to Donaldson Co., an estimated 40% to 50% of engine down-time is due to coolant system fail ure. This is more than just annoying, because most coolant system failure is avoidable. And with today's diesel engines putting out more heat, cooling system care has become even more important than before. Your engine coolant battles rust, scale formation, acidity, foaming, silicate drop-out and debris while it works to transfer heat and maintain the right operating conditions for optimal fuel economy. Two filtration solutions are available for light and heavy EGR engines with SCR emissions devices. OEMs using heavy EGR coolant systems will be seeing increased thermal cycling and accelerated coolant additive depletion.
