Radiator 28x19 Interchangeable Inlet

The Radiator 28x19 Interchangeable Inlet is a heavy-duty cooling core designed for serious engine builders and mechanics who demand reliable thermal management in custom and restoration automotive projects. This 28-inch by 19-inch core represents a versatile platform for classic car restorations, hot rod builds, and vintage truck applications where OEM radiators no longer meet modern cooling demands or dimensional constraints. Whether you're fabricating a custom loop system or replacing a failed original unit, this interchangeable inlet design offers the flexibility to adapt to various inlet configurations without compromising cooling capacity or durability.

At 16.6 pounds and measuring 23.75 by 6.13 by 30.75 inches, this radiator core balances substantial heat dissipation surface area with a relatively compact footprint—critical for tight engine bays in vintage platforms. The interchangeable inlet feature means you can orient and adapt the coolant entry point to match your specific plumbing layout, eliminating the need for custom fabrication or adapter fittings that compromise flow efficiency. The core's robust construction ensures consistent performance across extended operating temperatures, making it suitable for both street applications and spirited driving where sustained cooling demand is non-negotiable.

This radiator benefits restoration shops, hot rod fabricators, and DIY enthusiasts tackling engine swaps or cooling system upgrades on 1960s–1980s American vehicles and light trucks. The interchangeable inlet design proves invaluable when original radiator mounting bosses or inlet positions conflict with modern engine blocks, fuel injection systems, or custom headers. Installation typically requires basic mechanical knowledge, standard hose clamps, and compatible inlet adapters matched to your specific coolant line diameter and configuration—consult your build documentation to confirm compatibility before ordering.
