Radiator Chevy Double Pass 27.5in x 19in -16an

The FSR Racing Radiator Chevy Double Pass 27.5in x 19in with -16AN fittings is a high-capacity aluminum cooling solution engineered for Chevrolet high-performance and racing applications. This double-pass radiator delivers superior heat rejection compared to single-pass designs, making it essential for vehicles operating under sustained high-load conditions where stock cooling capacity falls short.

With dimensions of 27.5 inches wide by 19 inches tall, this aluminum radiator integrates passenger-side inlet and outlet configurations standard to Chevrolet cooling systems. The -16AN port sizing accommodates braided hose and fittings commonly used in custom and race cooling system builds, allowing precise control over coolant flow dynamics. At 22.8 pounds, the aluminum construction balances thermal performance with weight efficiency—critical for motorsports applications where cooling effectiveness must coexist with overall vehicle weight targets.

This radiator is purpose-built for street performance, track duty, and competition environments where engine temperatures demand reliable dissipation. The double-pass core design forces coolant through multiple pathways, maximizing surface contact and heat transfer efficiency. Ideal for modified Chevy engines producing elevated heat output, or any Chevrolet build where OEM cooling systems cannot sustain temperature control during extended high-rpm or high-boost operation.

FSR Racing radiators are recognized in the performance and racing community for engineered cooling solutions that prioritize function over appearance, delivering the thermal capacity serious builds require.
