FAQ'S

Which truck models are compatible with your heavy-duty radiators?
Our radiators are built to fit a wide range of heavy-duty trucks — including Freightliner, International, Peterbilt, Kenworth, Volvo, Mack, and Western Star — with matching core dimensions, inlet/outlet configurations, and mounting designs for direct replacements.

What materials and core designs do you offer?
We carry aluminum and copper/brass radiator cores, with options for standard and heavy-duty multi-row designs. These materials ensure strength, durability, and efficient heat transfer under demanding conditions.

How do I choose the right radiator for my truck?
Measure your current radiator’s height, width, and thickness, note port spacing, and mounting point locations. Match those specs or use your OEM part number to select a radiator that maintains proper coolant flow and cooling capacity.

Can I replace just the radiator core and reuse tanks or components?
Yes — in some bolt-together or modular radiator designs, you can replace just the core. Otherwise, replacing the full radiator assembly (cores, tanks, hardware) ensures a sealed, leak-free system.

What signs show my heavy-duty radiator is failing?
Watch for coolant leaks, overheating under load, warped fins, corrosion, or consistently high operating temperatures. Early replacement helps prevent engine damage, reduce downtime, and maintain performance.
