Mack Engine Coolant Filter

Prevent cylinder liner pitting and internal cooling system corrosion with the Mack Engine Coolant Filter. This spin-on unit contains supplemental additives that release into the coolant to maintain proper pH levels, which is essential for protecting the wet sleeves in Mack engines. The thick-walled steel canister is engineered to handle high-pressure surges and constant chassis vibration without developing pinhole leaks or stress cracks. Its internal filtration media captures fine particles like rust and sand before they can wear down water pump seals or clog the small passages in your heater core. The precision-threaded base allows the gasket to seat firmly against the filter head, ensuring a leak-free seal even during long-haul operations. Relying on this Mack 21937298 filter helps you avoid the high costs of an engine overhaul caused by cooling system neglect.
