Rust. Scale. Debris. Your engine battles them. And when it loses, you pay. Your cooling system keeps engine temperatures at the right level to dissipate heat and maintain the right operating conditions for optimal fuel economy. Donaldson coolant filters remove contaminants, minimize the risk of filter plugging and keep your engine running efficiently. Balance is the key in Coolant Filtration.
Coolant filters are designed to maintain the proper chemical balance and reduce contaminants in the engine cooling system.
