Purolator Heavy Duty Coolant Filters

Purolator Heavy Duty Coolant Filters are widely used in heavy duty diesel engines. They filter and trap contaminants from the coolant. In most configurations, Purolator Heavy Duty Coolant Filters distribute supplemental coolant additives (SCAs) and work with these SCA chemicals to maintain pH, fight corrosion and resist both cavitation erosion and deposit buildup.

Poor cooling maintenance causes an estimated 40% of all premature engine failures. Be sure to test your engine coolant at each scheduled service interval to maintain proper cooling protection. Consult your owner’s manual for service intervals.
