Radiator Universal Double Pass Closed 31x19

The PWR NORTH AMERICA Radiator Universal Double Pass Closed 31x19 is designed for serious engine builders and high-performance enthusiasts who require exceptional cooling efficiency in compact engine bays. This universal radiator is ideal for street rods, custom builds, and modified vehicles where standard OEM cooling capacity is insufficient. Whether you're upgrading a stroker engine, working on a boosted application, or restoring a classic car, this radiator meets the demands of modified power plants that produce more heat than stock configurations.

The double-pass core construction is a key feature, allowing coolant to enter one tank, pass through the core, reverse direction, and flow through again before exiting. This dual-path design maximizes heat transfer surface area and residence time, extracting more BTU capacity from a given core size compared to single-pass designs. The closed tank design offers secure mounting points and simplifies integration for custom fabrication.

Professional mechanics and fabricators trust PWR radiators for their reliability in cooler climates and moderate boost applications. The universal mounting design accommodates various configurations, making it suitable for applications where larger radiators may create clearance issues with suspension, steering, or intake manifolds. This radiator is a perfect choice for those looking to enhance their vehicle's cooling performance.
