17.5-inch Radiator for LS and LT Engine Swaps in 1964-1967 Pontiac GTO
When fitting an LS or LT motor into your 1964-1967 Pontiac GTO, maintaining correct engine temperature is essential. The 1964-1967 GTO Radiator 17.5" tall (Auto Trans) matches the original core height for a direct installation that preserves all hoses, shrouds, and brackets in their stock positions. Beyond precise fit, its all-aluminum construction delivers rapid heat rejection and resists corrosion for reliable service under road or track use. Ideal for A-body GTOs with automatic transmissions, it keeps coolant flowing smoothly whether you're cruising or tackling spirited drives.
Exact 17.5 inch Core Alignment for LS and LT Engines
This radiator's core height matches the factory 17.5 inch dimension exactly, ensuring a direct install without any trimming or modification. All coolant hoses, fan shrouds, and mounting brackets fit in their original locations, preserving the GTO's stock routing and appearance. By maintaining the OE alignment, you avoid clearance issues that often occur with undersized or oversized radiators. This level of precision is especially important when swapping in LS or LT powerplants, where engine placement is critical.
Lightweight Aluminum Construction for Rapid Heat Dissipation
Constructed entirely from high quality aluminum, the core and tanks deliver superior thermal conductivity compared to conventional materials. Aluminum's natural ability to transfer heat rapidly keeps engine coolant temperatures in check, even under sustained high load. The reduced mass up front also lightens the vehicle's nose, contributing to a more balanced driving feel and improved handling. Additionally, aluminum's inherent resistance to corrosion means long service life with minimal degradation.
Durable Finish with Bare Aluminum or Black Epoxy Options
Choose between a classic bare aluminum surface for maximum thermal transfer or a black epoxy coating for enhanced corrosion protection and visual appeal. The untreated finish allows for direct metal-to-air cooling efficiency, while the epoxy layer provides a barrier against moisture and road contaminants. Black epoxy also adds a refined look to the engine bay, matching modern or restored aesthetics. Both finishes are applied under controlled conditions to meet strict quality requirements.
Made in USA Craftsmanship for Reliable Performance
Manufactured domestically, each radiator undergoes rigorous inspection to guarantee consistent dimensions and flawless welds. Local production means tighter quality control and shorter lead times, so you receive a product that meets exacting standards without lengthy delays. The result is a cooling component built to withstand daily driving or occasional track use. Car owners appreciate the peace of mind and added resale appeal that comes with a genuine made in USA assembly.
