1964-1967 Pontiac GTO Radiator for LS and LT Engine Swaps
When adapting an LS or LT V8 into a 1964 through 1967 Pontiac GTO with automatic transmission the 15.5 inch tall radiator provides a direct drop in solution that preserves the original A Body core support and factory mounting points. Crafted from polished aluminum in the USA it maintains fan shroud alignment and correct hose angles so you avoid cutting or fabricating custom brackets. The design excels at shedding heat rapidly under demanding conditions and resists corrosion to sustain stable coolant flow. In every GTO swap this unit delivers reliable temperature control without modifying the frame or firewall connections.
Precision Alignment with Factory Core Support
This radiator is engineered to fit directly into the original A Body core support of a 1964 through 1967 Pontiac GTO, preserving the precise fan shroud alignment and hose angles established by the factory. By matching the stock 15.5 inch core height and automatic transmission cooler line locations, it eliminates the need for cutting or fabricating custom brackets. Installation requires only common hand tools and no alterations to the frame or firewall connections, ensuring a seamless integration of LS or LT powerplants into your classic GTO. The result is a swap that maintains the structural integrity and appearance of the original engine bay.
Advanced Heat Rejection from Polished Aluminum Construction
Constructed entirely from premium aluminum, this radiator excels at conducting heat away from the engine at a rapid rate, helping to prevent overheating under sustained load or spirited driving. The metal's natural corrosion resistance keeps coolant passages clear, reducing maintenance intervals and ensuring consistent flow profiles over many seasons. Aluminum also contributes to a lower overall weight up front, which helps preserve the GTO's handling balance and steering feel. This combination of thermal performance and light weight makes it a reliable choice for modern LS and LT installations.
Finish Selection for Restoration or Custom Builds
Builders can choose a bare aluminum surface for a classic engine bay shine or opt for a black epoxy coating to improve moisture protection in wet environments. The epoxy layer adheres evenly without obscuring the fin pattern, creating a uniform barrier against road salt and humidity. Each finish is applied in house under controlled conditions to guarantee consistent coverage and a refined appearance. These options allow restorers and customizers to match the radiator to any theme, from period correct to contemporary show car.
USA Assembly Delivering Consistent Quality
Manufactured and assembled in the United States, this radiator benefits from stringent quality control and rapid feedback loops to incorporate design enhancements. Domestic production adheres to industry guidelines for tank to core bonding and weld integrity, giving enthusiasts confidence in the strength and longevity of their cooling system. Supporting local craftsmanship also means shorter lead times and easier access to technical support or replacement parts. This level of oversight contributes to better resale value and sustained performance over the life of your GTO swap.
