1964-1967 Pontiac GTO Radiator for LS and LT Engine Swaps
When swapping an LS or LT engine into a 1964-1967 Pontiac GTO, retaining the original cooling layout is vital. This radiator installs in stock mounts without cutting to align with the factory 15.5 inch core height, preserving the stock fan shroud placement and hose angles while fitting transmission cooling line connections. Made entirely of aluminum with options for bare or black epoxy finish, it suits the A Body chassis and maintains consistent coolant flow from idle to highway speeds. Manufactured in the USA from corrosion resistant alloy, it delivers reliable performance and installation without welding.
Purpose Built for 1964–1967 GTO Vehicles
This radiator is engineered specifically for the 1964 through 1967 Pontiac GTO models equipped with an automatic transmission and a 15.5 inch tall core radiator opening. Its exact match to the original factory height ensures straightforward installation without the need for modification to the chassis or hood. By maintaining precise dimensions, it preserves the classic fitment profile while delivering modern cooling reliability.
Premium Aluminum Construction and Performance
Crafted from corrosion resistant aluminum, this radiator combines lightweight design with robust durability. The full aluminum core and tanks dissipate heat efficiently under heavy load, helping to control operating temperatures during spirited driving or daily use. Being manufactured in the USA guarantees rigorous quality control at every stage of production, from billet necks to welded seams, resulting in a component that meets or exceeds original equipment standards.
Optimized for LS and LT Engine Applications
Designed to support both LS and LT engine platforms, this unit delivers the coolant flow capacity required by modern powerplants. Integration with MuscleRods mount systems ensures precise alignment of the radiator inlet and outlet to the engine coolant ports, preserving correct drivetrain angles and preventing stress on coolant hoses. This seamless compatibility reduces installation time and provides confidence that the cooling circuit will operate at peak efficiency without strain on adjoining components.
