1964-1967 Pontiac GTO LS/LT Swap Radiator 15.5 Inch Tall with Fans
Converting a 1964 to 1967 Pontiac GTO A Body with LS or LT power often overwhelms the original 15.5 inch core cooling setup in slow traffic or during spirited driving. The 1964-1967 GTO Radiator 15.5" Tall (Auto Trans) with Fans provides a precise drop in fit to factory frame rails and automatic transmission cooler ports without trimming or custom brackets. Its all aluminum core and two pre installed fans sustain consistent coolant flow under sustained load while preserving underhood clearance. Available in bare aluminum or black epoxy, this USA made assembly simplifies installation and protects engine cooling under street or track conditions.
Precision Fitment for 1964-1967 GTO Radiator Applications
This radiator is engineered to replace the factory 15.5" tall core radiator in 1964 through 1967 GTO models equipped with automatic transmissions. It supports both LS and LT engine families without modification to the firewall or support structure. Careful attention to original mounting points allows seamless installation into existing brackets, preserving alignment between fan shroud and water pump pulley. This precision fitment minimizes installation time and eliminates the need for aftermarket spacers.
All-Aluminum Construction and High-Performance Fans
Constructed entirely from premium aluminum, this radiator offers superior thermal conductivity and resistance to corrosion compared to steel or plastic-tank units. The robust core and end tanks are precision welded to withstand constant pressure cycles and extreme under-hood temperatures. Dual high-performance fans are pre-installed for immediate operation, delivering strong airflow at idle and low vehicle speeds to stabilize coolant temperatures during heavy traffic or spirited driving. This fan setup works in tandem with the aluminum core to dissipate heat quickly and evenly, reducing the risk of boil-over and improving heater performance in cold-weather conditions.
Made in the USA for Long-Term Reliability
Proudly manufactured in the USA under rigorous quality control standards, each radiator undergoes a comprehensive pressure test to verify leak-free operation. The fully welded seams and durable aluminum alloy resist vibration and thermal stress over years of use. Ideal for restoration projects or high-demand street applications, this radiator meets or exceeds factory specifications. Its straightforward bolt-in design and plug-and-play fan assembly simplify the cooling system upgrade, providing a dependable solution for GTO owners who require consistent performance and peace of mind on every drive.
