LS and LT Swap Radiator for 1964-1967 Pontiac GTO A-Body
The 1964-1967 GTO Radiator 15.5" Tall Auto Trans with Fans is engineered to solve the overheating issues common in LS or LT swaps on Pontiac GTO A-Body models. It delivers a drop in fit into the original 15.5 inch core location and aligns with factory frame rails and cooler lines to eliminate trimming or bracket changes. Dual electric fans ensure consistent airflow across the entire core during idle in traffic or when lightly pushing the engine. Crafted from corrosion resistant aluminum and assembled in the USA this radiator supports reliable temperature control for both street driving and track days.
Precision Fit for LS and LT Engine Swaps
The 15.5 Inch radiator slides directly into the original core position on 1964 to 1967 GTO A Body frames without any trimming or extra brackets. It aligns with automatic transmission cooler lines and preserves the factory coolant routing to reduce potential leak points. Installers swapping LS or LT engines can maintain underhood clearance and hood latch engagement while speeding up the build process. This precise alignment ensures proper fluid flow and reliable temperature control under all driving conditions.
Consistent Airflow with Dual Electric Fans
Two high torque fans mounted on an integrated shroud draw air evenly through the full core surface to prevent hot spots during idle and low speed driving. By distributing airflow across every fin, pressure on the water pump is balanced which helps avoid cavitation and local boiling. This translates to steady temperature management in stop and go traffic or spirited highway runs. The fan arrangement also contributes to longer coolant life by minimizing steam pockets.
Durable Aluminum Core with Optional Coatings
Built from high quality aluminum the core features TIG welded joints and machined end tanks for structural strength that withstands vibration and thermal cycles. Aluminum's natural thermal conductivity allows rapid heat rejection while weighing less than original units to help maintain front end balance. Customers can choose a classic bare aluminum finish for a bright underhood look or opt for a black epoxy coat to enhance corrosion resistance. Each unit is assembled in the USA to guarantee consistent quality and performance.
