Coolant
Filters that Remove Contaminants and Maintain Cooling System Balance
It's estimated that 40 - 50% of engine downtime is due to coolant system failure. And with today's diesel engines, coolant balance is key to keeping your engine running efficiently. 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. Our coolant filters allow you to choose the method that suits your maintenance practices and schedules.
