17.5-inch Radiator with Fans for LS and LT Engine Swap in 1964-1967 Pontiac GTO A-Body
When adapting an LS or LT powerplant to a 1964 to 1967 Pontiac GTO A-Body chassis, precise core height and reliable cooling can make or break the project so the 1964 to 1967 GTO Radiator 17.5 inch Tall automatic transmission unit with fans tackles both challenges head on. By matching the factory 17.5 inch core dimension, this all aluminum radiator installs without trimming or bracket changes, preserving original mounting points and simplifying your swap. Its dual fans activate at low vehicle speeds, maintaining steady airflow whether you are cruising city streets or pushing your GTO on the track. Constructed for corrosion resistance and rapid heat rejection, it offers durable service life under varied driving conditions.
Precision Fit for Factory 17.5 inch Core
Matching the original core height streamlines the swap and preserves the GTO under hood architecture. By adhering to the 17.5 inch dimension the radiator installs directly into factory brackets without trimming or bracket changes. This exact fit reduces installation time and eliminates alignment guesswork that can lead to leaks or stress on mounting points. For restorers and hot rodders alike this straightforward approach helps maintain chassis integrity and keeps the process efficient.
Dual Fans Maintain Steady Airflow in Traffic
The pair of high output electric fans engage at low vehicle speeds to prevent heat soak in stop and go conditions. With two blades drawing air through the core the system sustains consistent coolant temperatures even during extended idling or tight city driving. This prevents temperature spikes that can rob power or trigger safety measures, ensuring the LS and LT engine stays within optimal range. Drivers can trust stable performance on the street or the strip without worrying about overheating.
Aluminum Body Ensures Rapid Heat Transfer
Fabricated from quality aluminum the radiator naturally conducts heat away from the coolant at a faster rate than traditional materials. The metal's low weight also reduces front end mass and improves overall balance in the A Body chassis. Its inherent corrosion resistance means the cooling system stays free of rust and scale over time, preserving flow capacity. Combined with precise welds the structure offers durability and sustained thermal efficiency under varied conditions.
Finish Options Provide Corrosion Protection
Choose between a raw aluminum surface that showcases the machine work or a black epoxy coating that adds a protective barrier against moisture and debris. The epoxy option extends lifespan in humid or road salt environments by preventing oxidation on exposed surfaces. Meanwhile the bare finish highlights the alloy grain and simplifies future inspections for leaks or damage. Both choices ensure the radiator remains serviceable and visually fitting for a classic GTO restoration.
