Radiator 19.5x27.75 Chev 16an Inlet No Filler

The Radiator 19.5x27.75 Chev 16an Inlet No Filler from HOWE is engineered for high-performance Chevrolet engines where cooling capacity and installation simplicity are non-negotiable. This unit is purpose-built for builders and enthusiasts running modified powerplants that demand superior thermal management without the complexity of traditional filler neck configurations. The no-filler design streamlines engine bay layouts, eliminates potential leak points at the cap seal, and integrates seamlessly into custom cooling systems where space or header clearance constraints demand a cleaner approach.

This aluminum core radiator features a 19.5-inch width and 27.75-inch height, delivering substantial surface area for efficient heat dissipation across a broad RPM range—critical when running boosted, supercharged, or naturally aspirated engines producing elevated coolant temperatures. The 16-AN inlet connection accommodates professional-grade braided or rigid aluminum hose plumbing, allowing builders to route coolant precisely without compromise. HOWE's construction emphasizes durability and flow optimization through internally enhanced tube design, ensuring coolant velocity and heat transfer efficiency remain constant even under sustained high-load operation on the street or track.

Technicians and engine builders working on LS-platform swaps, big-block restorations, or late-model Chevrolet performance builds will appreciate the flexibility this unit provides. Its no-filler design pairs particularly well with custom radiator brackets, remote reservoir systems, and tightly packaged engine compartments where conventional radiators create fitment conflicts. Installation requires proper hose sizing and fitting adapter selection to match your 16-AN inlet specification, making planning and precision measurement essential before ordering plumbing components. This radiator represents a professional-grade solution for those serious about thermal management and clean engine bay aesthetics.
