Cooling Packages
Cooling packages bundle radiators, fans, shrouds, coolant hoses, and thermostats into a single kit that addresses the complete cooling system rather than replacing one component at a time. Upgrading the cooling system as a coordinated package ensures all components are matched for flow rate, pressure rating, and connection size, delivering better temperature control than mixing individual components from different sources.Popular UpgradesAluminum radiator, electric fan, and shroud combo packages are the most popular choice for engine swaps, restomod builds, and high-output street cars where the factory cooling system cannot manage the increased heat rejection of a modified engine. High-performance cooling packages for towing applications that include a heavy-duty radiator, transmission cooler, and upgraded fan assembly are the most practical solution for trucks and SUVs that regularly tow at or near maximum capacity. Radiator and cap packages with pressure-matched components prevent...
