Mack Oil Coolers

Quality aftermarket oil coolers, like our OEM-equivalent replacements, are manufactured to match original Mack specifications for core density, fitment, and pressure ratings. When sourced from a specialized cooling supplier, aftermarket units perform comparably to OEM parts at a lower cost, without sacrificing durability or heat dissipation performance.

A standalone oil cooler manages hydraulic or engine oil temperature independently, while a combo unit integrates the radiator and oil cooler into a single assembly. Combo units simplify installation and save space on equipment with limited mounting room, whereas separate oil coolers offer more flexibility for custom cooling system configurations.

Installation time varies by truck model and cooler location but typically ranges from 1 to 3 hours for an experienced technician. Direct-fit, OEM-equivalent coolers reduce installation time since they require no custom fabrication or modification to existing mounting brackets, hoses, or fittings.

Premature failure is often caused by internal corrosion from contaminated coolant, debris buildup restricting airflow, excessive vibration causing seal fatigue, or operating beyond rated pressure and temperature limits. Regular coolant flushes, using OEM-spec fluids, and inspecting mounting hardware can significantly extend oil cooler service life.
