Factory-original cooling core designed for maximum heat rejection in heavy-duty applications. Built to OEM specifications for reliable performance under continuous operation. Direct replacement for fleet and owner-operator rebuilds.
Will this bolt directly into my truck without modification?
Yes — mounting points are factory-standard. Install using original fastener locations and hardware from your existing radiator bracket.
Do I need to flush the cooling system before installing this radiator?
Flush the system thoroughly before install to remove scale and debris. Old coolant can restrict flow and reduce cooling efficiency in the new core.
What if the radiator leaks within the first week?
Contact ModSupply with photos and receipt — returns handled case-by-case. Most issues stem from improper hose connections or overpressurization; verify all clamps are tight and your cap pressure rating matches OEM spec.
