17.5-Inch Radiator for LS and LT Swaps in 1964-1967 Pontiac GTO
If you are fitting an LS or LT engine into a 1964 to 1967 A-Body Pontiac GTO with an automatic transmission you need a cooling solution that aligns with the factory layout and avoids hose trimming. The 1964 to 1967 GTO Radiator 17.5" tall (Auto Trans) features a 17.5 inch core height that matches the original dimension for a direct installation preserving stock hoses shrouds and brackets. Crafted entirely from aluminum it offers fast heat rejection and natural corrosion resistance to keep coolant temperatures steady during spirited driving or daily use. By retaining all mounting points and coolant pathways installers sidestep clearance headaches and maintain correct engine and driveline alignment.
Precise 17.5 Inch Core Alignment for Seamless Engine Swap
When swapping an LS or LT engine into a 1964 to 1967 A Body Pontiac GTO with an automatic transmission preserving the original radiator height eliminates complex rerouting. The 17.5 inch core height matches the factory measurement so no cutting or trimming of hoses shrouds or brackets is required. Installers maintain the stock mounting points and coolant pathway geometry keeping engine placement true and reducing stress on ancillary components. This direct fit approach saves time and ensures the cooling system functions as intended without modifications that could affect reliability. A correct alignment also retains the classic under hood appearance. This design improves coolant circulation by maintaining factory port alignments and helps prevent air pockets that can reduce system efficiency.
All Aluminum Construction for Rapid Heat Transfer and Weight Savings
Constructed entirely from high quality aluminum the radiator maximizes heat transfer away from engine coolant keeping operating temperatures stable during spirited driving or heavy traffic. Aluminum’s low mass reduces front end weight improving vehicle balance and steering response. Its internal fin structure takes advantage of the metal’s conductivity to reject heat quickly over a large surface area. The robust internal passage design handles the increased flow demands of modern V8 setups without temperature spikes. Tubes and fins resist deformation under repeated heat cycles ensuring longevity. Natural corrosion resistance means the cooling system stays clean and free of scale with minimal maintenance. Together these traits deliver consistent performance whether on the street or track.
Coating Options Enhancing Durability and Engine Bay Appeal
Choose a bare aluminum finish for direct metal contact with air or opt for a black epoxy coating that adds a protective layer against moisture and road debris. The untreated surface allows maximum thermal output while the epoxy option helps guard against pitting in humid or salted road environments. Uniform application of either finish ensures full coverage and lasting adhesion without compromising cooling efficiency. Beyond protection the dark finish creates a visual contrast that highlights polished or painted engine components. Each epoxy finish is cured under controlled conditions to deliver uniform thickness and lasting protection, ensuring reliable performance in any climate.
Domestic Craftsmanship Delivering Consistent Quality
Manufactured in the USA each radiator undergoes thorough inspection at key stages of production to verify core height tank integrity and welding quality. Local fabrication allows strict control of material sourcing and process standards resulting in consistent fit and finish across every unit. This oversight reduces variability common in complex global supply networks and ensures each radiator meets exacting dimensional requirements. Owners benefit from reliable performance and a cooling solution that stands up to restoration grade builds and modern muscle car applications alike. Technical support and available service documentation further ensure installers have the guidance they need for a smooth fit. The result is a product that combines classic design with modern engineering confidence.
