Radiator 19 x 30 Double Pass w/Exchanger Open

The Radiator 19 x 30 Double Pass w/Exchanger Open from PWR North America is a high-capacity cooling solution designed for serious performance and custom vehicle builds. This unit is engineered for builders and mechanics who demand superior heat rejection in upgraded or heavily modified engines where OEM cooling capacity falls short. Whether you're running increased boost, extended track sessions, or simply need the reliability of a purpose-built radiator, this double-pass design delivers the thermal control required to keep engine temperatures stable under demanding conditions.

Double-pass radiator technology routes coolant through the core twice, maximizing contact time and heat transfer efficiency compared to traditional single-pass designs. The open-style exchanger configuration and 19 x 30 core dimensions provide substantial surface area for optimal cooling performance while maintaining a compact footprint suitable for tight engine bay installations. Aluminum construction throughout ensures lightweight durability and excellent thermal conductivity, critical for applications where every degree of coolant temperature reduction matters.

This radiator benefits engine builders, performance tuners, and motorsport enthusiasts preparing vehicles for high-performance applications. Its design eliminates unnecessary plumbing complexity while delivering core efficiency that matches or exceeds larger OEM units, making it ideal for engine swaps, forced induction builds, and high-output naturally aspirated platforms.
