Coolant Filter
Mack

The Coolant Filter is engineered to protect cooling system components by removing contaminants from the coolant loop before they can cause valve, radiator, or heater core damage. With robust filtration media and a durable housing, it supports sustained coolant purity, which helps maintain optimal engine temperatures and reduces the likelihood of clogging in flow paths. Filtered coolant contributes to longer pump and thermostat life and helps prevent corrosion in cooling circuits that are exposed to minerals, biofilms, and debris. Replacement is designed to be straightforward, enabling quick service in both shop and field environments. Clean coolant supports more reliable starts in cold weather and stable performance across high-heat conditions typical of long-haul operation. Source One Parts Center.
