Radiator Overflow Can Billet Natural Finish

The PROFORM Radiator Overflow Can Billet Natural Finish (SKU PFM69528) is a precision-engineered coolant recovery system designed for serious automotive builders and engine swap enthusiasts. Built from billet aluminum, this overflow canister serves as the critical link between your radiator and cooling system, capturing excess coolant as engine temperatures fluctuate during operation. Whether you're tuning a high-performance street engine or restoring a classic vehicle, this component provides both functional reliability and a clean, professional appearance under the hood.

Machined from solid billet aluminum in a natural finish, this overflow canister features 90-degree hose barb fittings that ensure secure, leak-free connections to your radiator inlet and overflow return lines. The natural aluminum aesthetic integrates seamlessly into custom engine bays where stock plastic canisters would look out of place. Standing 6.75 inches tall with a 3-inch outer diameter, the canister provides adequate volume for coolant expansion while maintaining a compact footprint suitable for engine compartments with tight spacing constraints. The billet construction eliminates plastic degradation issues common in OEM units, offering superior durability under sustained heat cycles and aggressive driving conditions.

This radiator overflow can is ideal for custom-built engines, LS swaps, small-block conversions, and any performance application where cooling system reliability is non-negotiable. Mechanics and fabricators appreciate the billet construction for its rigidity and resistance to corrosion, making it a long-term investment in cooling system integrity. Installation requires basic hose routing knowledge and compatible hose sizes that match the 90-degree barb fittings; ensure your cooling system's inlet and overflow tubes align with standard radiator hose diameters. The natural finish allows for anodizing customization if desired, giving builders the flexibility to match their specific color scheme and detail work.
