LS and LT Radiator 15.5-inch for 1964-1967 Pontiac GTO Manual Transmission
Fitting an LS or LT engine into a 1964 through 1967 GTO A body with a manual gearbox can turn radiator clearance into a major headache so this 15.5 inch tall unit is shaped to drop precisely into stock mounts and keep hose angles factory correct. Its aluminum core pulls heat quickly under sustained load while inlet and outlet ports align with factory hose positions to avoid cutting or grinding frame rails. Precision fabrication in the USA ensures consistent coolant flow and retains the original fan shroud location for simplified fan installation. The result is reliable temperature control without modifying brackets or sacrificing body structure during the swap.
Precision Fit for 1964-1967 GTO A Body Manual Transmission
The radiator stands 15.5 inch tall to match the original core height found in 1964 through 1967 GTO A Body models with a manual transmission. It drops directly into stock mounting points and aligns inlet and outlet ports with factory hose positions so installing it requires no cutting or grinding of frame rails or brackets. This exact fit preserves the original fan shroud location and maintains the coolant path engineered by Pontiac. By eliminating modifications to the body structure, this unit keeps assembly simple and helps maintain chassis strength. Owners benefit from a swap solution that fits like the factory part and delivers consistent performance under all driving conditions.
Efficient Aluminum Core for LS and LT Engine Cooling
Constructed from premium grade aluminum, the core pulls heat rapidly from modern LS and LT engines under sustained load. The tube and fin design maximizes surface area contact with airflow and delivers stable coolant temperatures during both highway driving and spirited runs. Aluminum material offers superior resistance to corrosion and electrolyte damage compared to traditional metals, ensuring years of reliable use. Its lightweight nature reduces front end mass, which can improve handling and balance in the classic GTO chassis. Together, these attributes provide strong thermal management that matches the demands of a high output V8 swap.
Bare Aluminum and Epoxy Coating for Corrosion Protection
This radiator can be finished in bare aluminum for easy visual inspection of weld seams or in a durable black epoxy that shields the core from road debris and moisture. The epoxy layer is applied under strict quality control to form a barrier against oxidation while preserving a sleek appearance. Bare surface finish allows early detection of damage or leaks, so maintenance can be performed before issues escalate. The coated option extends service life and guards against environmental hazards in wet or salty conditions. Both finishes offer a balance of functionality and style that complements a restored GTO front end.
Manufactured in the USA for Reliable Quality and Fit
Every unit is fabricated domestically with precision tooling and strict dimensional checks to ensure consistent fitment in A Body GTO frames. By controlling the entire production process, from core assembly to port alignment, quality remains uniform from one radiator to the next. This local production also supports faster delivery times and provides assurance that specifications meet or exceed factory tolerances. The result is a part that not only enhances cooling performance but also holds its value as an authentic swap component. Enthusiasts can trust in both its craftsmanship and its contribution to long term vehicle integrity.
