17.5" Tall Radiator with Fans for LS/LT Swap in 1964-1967 Pontiac GTO
When fitting an LS or LT powerplant into a 1964 to 1967 GTO A Body with automatic transmission, retaining the factory height is vital for hassle free installation and reliable heat rejection. The 1964 to 1967 GTO Radiator 17.5" Tall (Auto Trans) with Fans meets this need by matching the exact 17.5 inch core height for a drop-in placement. Constructed from high quality aluminum in the USA, it offers precise dimensions and corrosion resistance. As a direct drop in replacement, coolant hoses align naturally and maintain proper bend radii without the need for trimming or bracket changes. Dual electric fans ensure airflow at low speed without altering hose routing or brackets. Available in bare aluminum or black epoxy, each unit arrives ready to bolt in and perform across varied driving conditions.
Precision Fitment for 1964–1967 GTO Applications
This radiator is designed specifically for 1964 through 1967 GTO models equipped with automatic transmissions and original 17.5 inch tall core units. It accepts LS and LT series engines without modification to the front sheetmetal or factory rails. Installation uses the factory upper and lower mounts to keep the radiator positioned exactly where the original unit sat, ensuring coolant hoses and transmission cooler lines connect without rerouting. Cars that use MuscleRods crossmembers or frame mounts benefit from exact alignment at the radiator inlet and outlet, preserving proper coolant flow and maintaining correct engine cradle geometry throughout the chassis.
Premium Aluminum Construction and Cooling Capacity
Built from premium aluminum, this unit combines low mass with excellent heat transfer to manage modern power outputs. The 17.5 inch tall core increases surface area over smaller aftermarket replacements, so it sheds heat more effectively under sustained load. Dual fans are installed at the factory, delivering balanced airflow across the entire core even at idle or in slow traffic. Fan wiring arrives preterminated to integrate with existing harnesses, so you plug in each connector and secure the shroud. With no need for bending brackets or trimming sheetmetal, installation time is reduced and fitment is precise.
Made in the USA with Factory Integration
Manufactured entirely in the USA, each radiator undergoes pressure testing and leak inspection before it ships. The all aluminum design resists corrosion common to mixed metal cores, making it ideal for both street use and hard driving conditions. Fans have sealed motor housings to protect against debris and moisture. When combined with MuscleRods mounting brackets, the assembly holds true to factory dimensions for engine placement and driveshaft angles, eliminating guesswork during engine swaps. The end result is a durable cooling solution that retains classic appearance while offering modern performance and reliability.
