Radiator 18.5x31 Single Pass Low Outlet Open

The Radiator 18.5x31 Single Pass Low Outlet Open from PWR NORTH AMERICA is designed for builders and enthusiasts focused on efficient thermal management in modified street and performance vehicles. This aluminum radiator is built to accommodate the elevated coolant flow rates required by modern high-output engines and aggressive cooling system modifications.

Featuring a single-pass design, this radiator optimizes coolant velocity through the core matrix, allowing for faster heat transfer compared to multi-pass configurations. This is particularly beneficial during track days or towing when cooling capacity is critical. The low outlet positioning aids in gravity-assisted drain and bleed operations, minimizing air pockets that can hinder cooling efficiency.

Ideal for builders upgrading to higher power outputs, classic car restorers enhancing cooling systems, and mechanics working on performance builds, this radiator's open tank design allows for easy integration with aftermarket fill necks and custom plumbing layouts. Its core footprint balances cooling area with installation flexibility, making it a versatile choice for various applications.
