Radiator 19x31 Chevy Dual Pass No Filler

The HOWE Radiator 19x31 Chevy Dual Pass No Filler is a high-performance aluminum cooling solution engineered for Chevrolet platforms requiring efficient heat rejection and compact installation. Built from aluminum construction, this dual-pass radiator delivers superior thermal efficiency compared to single-pass designs by routing coolant through two separate flow paths, maximizing contact time between coolant and cooling fins for aggressive heat dissipation in street, strip, and road racing applications.

The no-filler neck design eliminates the traditional filler cap location, streamlining engine bay aesthetics and reducing overall radiator height to 20 inches—a critical dimension for custom builds with tight underhood clearance or modified engine placement. Measuring 30.75 inches wide with a 3-inch core depth, this Chevy radiator fits within standard mounting points while the passenger-side inlet and outlet configuration accommodates common hose routing layouts. At 20.5 pounds, the aluminum core provides weight savings over older cast-iron designs without sacrificing durability or cooling capacity, making the HOWE 19x31 a preferred choice for street rod builds, vintage restoration projects, and custom hot rod platforms where both form and thermal performance matter.

This radiator suits builders and enthusiasts restoring or modifying second-generation and third-generation Chevrolet vehicles who need reliable cooling in street-driven or occasional track-use scenarios. The dual-pass core design is particularly effective for engines producing moderate to high horsepower outputs where standard cooling becomes marginal. Installers value HOWE's reputation for precision fit and construction quality, reducing fitment troubleshooting and ensuring long service life across varied driving conditions—from cruising to sustained performance driving.
