Donaldson describes its Endurance Plus Coolant filter as a simple, reliable filtration solution that maintains coolant quality in diesel engines. Donaldson Endurance Plus extended service life coolant filters come equipped with additive replenishment technology and are suited for direct replacement to standard coolant filters in engines without modification or special maintenance.

Designed for standard coolants ethylene glycol and propylene glycol, the replenishing coolant additive technology is formulated to extend coolant life and protect against corrosion, cavitation erosion, scale deposits and inhibitor drop. Donaldson says the additive technology, using a controlled chemical release process and Synteq filtration media, maintains healthy coolant conditions more effectively than standard cellulose filter media.

Donaldson filters with Endurance Plus additive technology are suited for extended coolant maintenance programs with improved coolant maintenance intervals at once a year or 150,000 miles. For more information, go to
