When preparing a Pontiac GTO A-Body LS or LT engine swap on an automatic, a radiator that preserves factory dimensions is vital. The 1964-1967 GTO Radiator 17.5" tall (Auto Trans) fits with a 17.5-inch core height into original hose, shroud and bracket locations with no trimming. Made from aluminum for corrosion resistance and solidity, it delivers fast heat rejection while cutting front end weight. Offered in bare or black epoxy coated finish and built in the USA, it matches OE inlet and outlet placements for direct installation.
1964-1967 GTO Radiator, 17.5 inch Core Height
This radiator is engineered specifically for 1964 through 1967 GTO models equipped with a factory 17.5 inch tall core and automatic transmission. It accepts LS or LT engine packages without modification. By preserving the original core height, it aligns with factory hose locations and clears the original fan shroud and support brackets. The exact fit eliminates the need for custom trimming or shimming, ensuring a straightforward update for classic GTO restoration or performance upgrades.
Compatibility with MuscleRods Mounts
Designed to work seamlessly with MuscleRods engine mounts, this unit maintains precise engine placement and correct drivetrain angles. That partnership guarantees proper clearance around the steering shaft, cross member, and front suspension components. By matching the factory mounting points, the radiator supports consistent belt alignment and prevents undue stress on water pump and alternator shafts, preserving long-term reliability.
Construction and Thermal Performance
Built from premium aluminum, the core and tanks are fully welded and pressure-tested for leak-free operation. Aluminum’s high thermal conductivity allows rapid heat transfer away from coolant, reducing risk of overheating under sustained load. Thicker end-tank walls bolster resistance to vibration and pressure fluctuations. This design yields consistent coolant flow and superior cooling capacity compared to original copper-brass units, enhancing both daily driving and track use.
Made in the USA and Quality Assurance
Manufactured domestically under strict quality control standards, each radiator undergoes dimensional inspection and flow testing before shipment. US production ensures traceable material sourcing and adherence to precise welding and alloy specifications. Buyers benefit from rapid turnaround times, local support, and a product that meets or exceeds OEM tolerances. This commitment to American craftsmanship delivers dependable cooling performance for classic GTO restorations.
