LS and LT Radiator for 1973-1974 Chevy Nova and Pontiac Ventura
Engineered for LS and LT engine swaps into 1973 to 1974 Chevy Nova and Pontiac Ventura frames, the 1984 to 1989 Corvette Radiator (Auto and Manual Trans) delivers a ready fit cooling solution without extra brackets or adapters. With its single-fan package drawing minimal current, airflow moves evenly through the aluminum core for stable coolant temperatures under varying loads. Crafted from corrosion resistant alloy and weighing less than stock steel radiators, it bolts directly to factory hose connections on the X Body rails for a clean installation. This design ensures dependable heat rejection whether on the street or at the track.
Single Fan Architecture for Balanced Airflow
The radiator's single fan design draws minimal amperage while still moving sufficient air through the entire core when the engine is under load. By concentrating airflow across a uniform surface area, it prevents hotspots that can lead to coolant boiling or uneven temperature distribution. This configuration also clears the narrow space between the engine accessories and frame rails, avoiding interference that often demands custom shrouds or bulky adapters. In practical terms, the reduced electrical draw leaves more charging capacity for starter and lighting functions during extended idling or spirited driving. Overall, the simple fan layout delivers predictable cooling performance without placing extra demands on the vehicle's electrical system.
High Efficiency Aluminum Core Construction
Every coolant passage and fin in this radiator is formed from premium aluminum to maximize heat transfer rates and resist corrosion in humid or road salt environments. Aluminum's naturally high thermal conductivity enables rapid rejection of engine heat into passing air, resulting in stable operating temperatures even when climbing steep grades or towing heavy loads. Lightweight by design, the assembly reduces front-end mass and contributes to sharper throttle response and handling balance. Over time, the corrosion resistance of the alloy helps maintain full coolant flow without the need for frequent flushing or patch repairs. Together, these material advantages ensure LS and LT powerplants remain within safe temperature parameters on both highway runs and track days.
Direct Fitment to 1973 1974 X Body Frame Rails
Engineered specifically for the 1973 and 1974 Chevy Nova and Pontiac Ventura chassis, this radiator installs into original mounting brackets without any extra hardware. The inlet and outlet ports align precisely with factory hose connections on the frame rails, allowing coolant and transmission lines to follow their intended path without kinks or stress points. Precision-machined mounting tabs provide a secure, vibration-resistant interface that helps prevent leaks after repeated exposure to road shock. By eliminating custom brackets or trial-and-error alignments, installation time is cut dramatically and the potential for assembly mistakes is reduced. Whether tackled by a seasoned technician or a dedicated do-it-yourself enthusiast, the result is a neat underhood arrangement and consistent coolant circulation from day one.
