Luber-finer says its extended service coolant filters were developed to maintain and protect cooling systems during extended service intervals of up to 1 year, 150,000 miles or 4,000 hours. Designed for use with conventional coolant, ethylene or propylene glycol, the filters have a specially formulated synthetic media and are pre-charged with the company’s Controlled Release Technology supplemental coolant additive, formulated to protect engines against harmful corrosion, cavitation and scale when longer service intervals are needed.

The filters are constructed of a durable epoxy-coated shell designed to resist rust and corrosion during extended service. A protective holding chamber inside the shell helps keep CRT coolant separate from filter media to prevent degradation and provide even release; as the CRT releases controlled levels of supplemental coolant additive, the vehicle’s engine is protected against rust, scale and other build-up that can damage key components and cause early engine failures, according to the company.

The new filters also are designed with an all-steel base plate to provide added durability and strength for stability over extended service levels, as well as a double-rolled seam for a tighter fit to help prevent leakage. For more information, go to
