15.5" Tall Radiator with Fans for LS and LT Manual Trans 1964-1967 Pontiac GTO
If you are fitting an LS or LT engine into a 1964 to 1967 Pontiac GTO manual chassis, you need a radiator that makes installation straightforward with no rail trimming or bracket changes. The design preserves original hose routing and underhood clearance by matching factory 15.5 inch core height and stock mounting points for a true drop-in installation. Featuring dual electric fans that activate based on coolant temperature, it maintains consistent airflow at idle or in stop and go traffic. Aluminum construction delivers quick heat rejection and corrosion resistance for long service life under street and track demands.
Precision Fit for 15.5 Inch Core GTO Chassis
Installing this radiator in a 1964-1967 Pontiac GTO manual transmission frame ensures exact alignment with the original A-Body mounting points. By replicating the factory 15.5 inch core height and bracket locations, there is no need for rail trimming or custom bracket fabrication. This precision fit preserves underhood clearance and maintains the correct hose routing found in stock applications. Builders avoid the common pitfalls of misaligned connections that can lead to coolant leaks or interference with other engine bay components. The result is a streamlined installation process that saves time and guarantees a reliable foundation for LS and LT engine swaps.
Dual Fan Cooling for Stable Temperature Control
Equipped with two high-flow electric fans, this system delivers consistent airflow across the core even when the vehicle is stationary or crawling in traffic. Each fan engages automatically based on coolant temperature, eliminating the need for manual switching or complex relay setups. The parallel operation of both fans prevents localized hot spots and maintains optimal coolant temperatures during extended highway runs or spirited track sessions. A simple plug and play wiring harness integrates seamlessly with existing electrical circuits, reducing installation steps. Drivers benefit from steady performance under varying load conditions without sacrificing engine bay space.
High Quality Aluminum Core for Rapid Heat Rejection
The radiator core and end tanks are fabricated from 100 percent aluminum to maximize thermal conductivity while minimizing weight compared to steel alternatives. A precision fin and tube architecture increases the surface area in contact with airflow, enabling swift heat transfer even under heavy engine loads typical of LS and LT powerplants. Aluminum's inherent resistance to corrosion helps prevent scale buildup and pitting over time, extending service intervals and overall longevity. By carrying less mass at the front of the vehicle, this lightweight assembly also contributes to improved handling balance without compromising structural strength. Rigorous quality control ensures each unit meets or exceeds the heat output demands of modern swap applications.
Protective Coatings for Corrosion Resistance and Appearance
Customers have the option of a classic bare aluminum finish or a durable black epoxy treatment to suit different styling preferences. The bare surface showcases the natural luster of wrought aluminum, while the epoxy coating adds a protective barrier against moisture, road salts and debris. The epoxy bonds tightly to the metal substrate, reducing the risk of surface oxidation and pitting in humid or coastal environments. Both finishes are easy to maintain with simple cleaning methods, ensuring the radiator continues to look as well as it performs over the seasons. This flexibility in appearance allows builders to achieve a tailored engine bay presentation without sacrificing functional protection.
