17.5 Inch Tall Radiator for Manual Trans LS and LT Swaps in 1964-1967 Pontiac GTO
When fitting an LS or LT engine into a 1964 through 1967 Pontiac GTO A Body with a manual transmission the 1964-1967 GTO Radiator 17.5" Tall (Manual Trans) with Fans ensures precise coolant system integration. Its 17.5 inch tall core matches the original opening to allow a direct drop in fit on stock mounts without trimming or bracket modification. Constructed of aluminum for light weight and corrosion resistance this unit includes two high performance fans to maintain stable coolant temperatures in traffic and on track. Finish options of bare aluminum or black epoxy coat protect the core and preserve thermal efficiency while being built in the USA for consistent quality.
Precision Fitment for 1964-1967 GTO Chassis
The radiator is engineered specifically for 1964 through 1967 GTO models that originally housed a 17.5" tall core and manual transmission. This exact match to factory dimensions ensures that it drops into place without modification to the core support or inner fender area. Inlet and outlet ports mirror the original item, eliminating the need for hose adapters and preserving firewall clearance. Integration with MuscleRods mounting components maintains proper engine location and optimal driveshaft angle for flawless power transfer and minimal vibration.
Optimized Dual High-performance Fans
Equipped with two high-performance electric fans right out of the box, this assembly delivers consistent cooling across all operating speeds. These fans feature engineered blade profiles for maximum airflow and minimal draw on the electrical system. Combined output exceeds the original design, which is critical when running LS or LT powerplants that generate higher heat at idle or under load. They maintain coolant temperatures within safe limits in heavy traffic or on challenging inclines. Standard connectors plug into factory circuits or aftermarket controllers, making fan activation seamless based on coolant temperature and engine demand.
Durable High-Quality Aluminum Construction
Every radiator is built from premium aluminum alloy that offers superior thermal conductivity and a high corrosion threshold. The core is precision folded and brazed to guarantee long service life under repeated heating cycles. Core thickness and fin density are optimized to balance cooling capacity with flow resistance. The multi tube passage design eliminates hot spots, ensuring even coolant distribution and reducing strain on water pump bearings. Tanks and end caps are cast to tight tolerances for leak free performance while lowering front end mass to aid steering response.
Proudly Made in the USA with Rigorous Testing
Manufacturing occurs entirely in the USA under strict quality protocols. Each unit undergoes pressure testing to ensure zero leaks before it leaves the factory. Fabrication through robotic welding stations and laser alignment checks guarantees repeatable measurements and consistent fitment. Final assembly includes full system verification covering fan activation thresholds and temperature response times. Backed by dedicated technical support, this radiator offers genuine replacement appeal and reliable performance for restorations or high output builds.
