1964-1967 Pontiac GTO Radiator for LS and LT Swaps
When swapping an LS or LT engine into a 1964 to 1967 Pontiac GTO the narrow factory core opening leaves almost no margin for installation errors or custom bracket work. This 17.5 inch tall radiator for manual transmission applications provides direct drop in fit by matching the original core height and clearing steering and transmission components without modifications. Built entirely from high quality aluminum in the USA the design pairs a full aluminum core with dual factory installed fans to pull air evenly through every tube row. Additional reduction in front end weight helps maintain balanced handling whether cruising city streets or laying down laps at the track.
Exact Core Alignment for Hassle Free Installation
The 17.5 inch tall radiator core matches the original opening in 1964 to 1967 Pontiac GTO models. This precise match removes the need for trimming or custom bracket work, preserving factory mounting points and structural integrity. When seated flush against the support structure, the radiator maintains proper clearance around steering linkages and the manual transmission housing so coolant lines route naturally without abrasion. Uniform mounting also limits vibration that can cause premature hose wear, and it ensures coolant travels through each tube row at an even rate. The result is a seamless integration that safeguards consistent heat transfer across the entire core under varied driving conditions.
Lightweight Aluminum Build for Improved Balance and Thermal Efficiency
Constructed completely from premium grade aluminum, this radiator excels at drawing heat away from the engine coolant and releasing it rapidly into the surrounding air. The reduced mass at the front of the GTO contributes to better weight distribution and sharper steering response under acceleration or cornering. Aluminum's natural corrosion resistance helps the core withstand exposure to road salts, moisture, and other environmental factors without pitting or failing. Thermal cycling over time will not lead to warping or cracking, so the radiator retains its efficiency and shape through repeated use. In practice, this means more stable coolant temperatures and greater peace of mind on both street drives and track sessions.
Factory Installed Dual Fan System for Consistent Cooling
Two high capacity fans are bonded to the radiator at the factory to guarantee steady airflow through every tube row. In stop and go traffic or during low speed maneuvers, the fans engage automatically to maintain coolant temperature within the optimal band. When you push the engine under load or on the strip, the additional air volume prevents sudden spikes in temperature that could lead to overheating. Preassembled fans eliminate the need for custom brackets or wiring hacks, and they avoid interference with hoses and linkages in the engine bay. The integrated design ensures reliable cooling performance whether you are cruising city streets or working the GTO hard on race day.
Bare Metal or Epoxy Film for Corrosion Protection and Style
Choose the classic bare metal finish to showcase precision welds and the natural shine of aluminum, or select a black epoxy film for enhanced protection against moisture intrusion, road debris, and chemical exposure. The epoxy coating is applied with meticulous attention to coverage and thickness to maintain the radiator's rapid heat rejection. Under the hood, the bare metal option highlights craftsmanship and provides an unobstructed view of every tube and fin interface. Both finishes deliver long lasting corrosion resistance, preserving core integrity and performance over many seasons. This flexibility lets you tailor the look of your engine bay without compromising on durability.
