Heavy Duty Truck Radiators

Passenger car radiators typically range from $150 to $500, but heavy-duty truck radiators cost significantly more due to their size and cooling capacity. Truck radiator cores in our catalog range from roughly $1,487 to over $25,000, while complete assemblies for models like the Peterbilt 379 or Volvo/Mack VN780 run between $2,900 and $5,800.

A radiator core is the internal heat-exchange component made of tubes and fins, while a complete radiator includes the core plus top and bottom tanks, mounting brackets, and fittings. Cores are often used for rebuilding existing units, while complete radiators are ready for direct installation without additional tank sourcing.

We supply both OEM-sourced radiators, such as our Peterbilt 379 core, and OEM-equivalent aftermarket options through our ICEBOX Replacement Parts program. All parts are engineered to match original specifications for fit, heat rejection, and durability across major truck brands.

Our catalog covers radiator cores and radiators for major heavy-duty brands including Peterbilt, Kenworth, Freightliner, Volvo, Mack, International, and Western Star, along with specialty applications like fire trucks and buses. Contact us if your specific model isn't listed online.

Common warning signs include frequent overheating, visible coolant leaks, corrosion or damage to the core fins, reduced airflow, and declining engine performance under load. If your truck regularly runs hot on long hauls or shows coolant loss, inspecting and likely replacing the radiator or core is recommended.

Yes. Beyond standalone radiators and cores, we offer complete cooling packages that bundle radiators, charge air coolers, oil coolers, and mounting hardware for a range of heavy-duty and industrial engines, simplifying procurement for full cooling system replacements or rebuilds.
