Radiator for LS and LT engine swap in 1964-1967 Pontiac GTO
When installing an LS or LT mill into your 1964 to 1967 Pontiac GTO, precise cooling is essential and the 1964-1967 GTO Radiator 17.5" Tall (Manual Trans) with Fans is engineered to tackle that challenge. Featuring a 17.5 inch tall core and dual fans, it sustains coolant flow during stop and go traffic or spirited runs. The aluminum construction is lightweight yet sturdy and designed for direct fit into factory core locations without trimming or extra brackets. Drivers will appreciate consistent engine temperatures and easier installation for any street or track swap application.
Precision Core Height for 1964-1967 GTO
The 17.5 inch tall core aligns exactly with the original radiator space in Pontiac GTO models from 1964 to 1967, eliminating trimming or custom brackets. By matching factory dimensions, this design streamlines the installation process for LS and LT engine swaps while preserving clearance for manual transmission components. Precise alignment ensures coolant flows uniformly through every row of tubes, maximizing the surface area used for heat rejection. This drop-in fitment removes guesswork and significantly reduces installation time.
Aluminum Construction for Rapid Heat Rejection
Constructed from high quality aluminum, both the core and end tanks deliver exceptional thermal conductivity and resist corrosion under constant exposure to coolant. This metal alloy is light yet robust, reducing front end weight and improving overall vehicle balance. The fast heat transfer rate of 1000 series aluminum alloys keeps engine temperatures stable during spirited driving or extended highway runs. As an added benefit, the material withstands repeated temperature cycles without cracking or warping, ensuring long service life.
Dual Fan Assembly for Consistent Engine Temperatures
Two high capacity fans are preinstalled to maintain airflow even during idle and stop-and-go traffic, keeping coolant circulating through the radiator core. This dual setup pulls air evenly across the entire 17.5 inch surface, reducing hotspots that can occur under heavy load or on the drag strip. Fans engage automatically to support the LS and LT engines' cooling demands and lower the risk of overheating during track sessions. Because they arrive mounted on the radiator, there's no need for extra brackets or complex wiring.
Coating Options Enhance Protection and Aesthetics
Choose between the natural bare aluminum finish or a black epoxy coating to match your engine bay's appearance and corrosion needs. The epoxy option adds a uniform protective barrier against road debris, moisture, and environmental exposure, while the bare finish highlights the core's precision welds and natural luster. Both finishes are applied locally to ensure consistent coverage and quality control. This selection flexibility lets builders maintain classic style or pursue a stealth look without compromising durability.
