1964-1967 Pontiac GTO Radiator for LS and LT Engine Swaps

When fitting an LS or LT engine into a 1964-1967 Pontiac GTO the challenge of keeping coolant temperatures in check can make or break your build. This 1964-1967 GTO Radiator 15.5 inches tall for manual transmissions slides into the stock mounts and aligns perfectly with factory hose locations. Offered in bare aluminum or black epoxy it resists corrosion and accelerates heat transfer for reliable performance under pressure. Installation requires minimal modification to the stock frame so you can return your classic car to the road with confidence.

Precision Factory Fitment for Manual Transmission GTO

This radiator is engineered to drop into the stock mounts of 1964-1967 Pontiac GTOs with manual transmissions, preserving the original hose angles and fanshroud alignment without cutting or grinding. Its exact 15.5-inch height ensures the core sits flush in the factory location, eliminating clearance issues that often arise with generic replacements. By maintaining the stock frame structure, the risk of misalignment is virtually removed, reducing installation time and potential frame stress. The result is a seamless integration that upholds chassis integrity and coolant flow as designed by Pontiac engineers.

Premium Grade Aluminum Core for Efficient Engine Cooling

Made entirely from premium grade aluminum, the core delivers exceptional thermal conductivity to accelerate heat rejection from LS and LT engines. Aluminum's innate resistance to corrosion helps the radiator fend off pitting and electrolyte damage, ensuring sustained performance over many seasons. Its lightweight construction also lowers front end mass, subtly enhancing handling and balance on the road. Additionally, the optimized tube and fin arrangement maximizes surface contact with airflow, stabilizing coolant temperature under spirited driving or highway cruising alike.

Tailored Finish Options That Combine Protection and Visual Appeal

Available in classic bare aluminum or a protective black epoxy finish, this radiator lets builders choose between timeless polish or a robust coating that resists moisture and road debris. The black epoxy layer forms a durable shield against corrosion, while the bare aluminum option highlights the weld craftsmanship and simplifies visual inspections. Each finish is applied under stringent quality standards to guarantee uniform coverage and strong adhesion. Together, these choices deliver both aesthetic customization and dependable long-term protection for your classic GTO's cooling system.
