LS and LT Radiator for 1973-1974 Chevy Nova and Ventura X-Body
The 1984-1989 Corvette Radiator (Auto and Manual Trans) controls underhood temperatures when transplanting LS or LT engines into 1973-1974 Chevy Nova and Pontiac Ventura X-Body installations and fits between frame rails and accessory brackets on the GM chassis. A slim single fan package draws minimal current from the charging system while directing airflow through the core for consistent cooling during street or track use. Constructed from corrosion resistant aluminum, the radiator core and tanks shed heat quickly and reduce overall system weight for sharper engine response. Installation is straightforward with direct attachment to factory hose connections and X Body mounting points and eliminates the need for brackets or adapters while ensuring precise coolant and transmission line routing.
Slim Single-Fan Design for Efficient Cooling
The slim single-fan package is engineered to draw minimal current from the charging system while maintaining strong airflow through the radiator core. Its low profile fits neatly between frame rails and engine accessories, preserving underhood clearance and simplifying cable routing. Because it requires less amperage than dual setups, the fan keeps more electrical capacity available for starter and lighting functions, which is crucial during track sessions or night drives. The focused airflow path ensures even heat rejection across the entire core, helping to stabilize coolant temperatures whether you are idling in traffic or cruising at speed. Overall, this arrangement provides dependable cooling performance without overtaxing the vehicle's electrical system.
Lightweight Aluminum Core for Rapid Heat Transfer
Constructed entirely from premium aluminum, the radiator core and tanks leverage the material’s high thermal conductivity to shed heat quickly. Aluminum resists corrosion and pitting in humid or salt-exposed environments, ensuring structural integrity over time without adding significant weight. The reduced mass of this design contributes to sharper throttle response and improved front end balance, which can be felt as more precise handling and quicker acceleration. Compared with traditional copper units, the lightweight assembly also reduces strain on mounting points and makes service access easier. These material advantages combine to protect your LS or LT engine under demanding conditions.
Direct Fitment on 1973–1974 X Body Chassis
Engineers preserved the original mounting dimensions and hose connection locations of the X Body platform, allowing this radiator to bolt directly onto 1973–1974 Chevy Nova and Ventura frames without the need for custom brackets. The precision machining at each attachment point delivers a secure, leak-free seal and streamlines installation, saving hours in fabrication work. With factory hose ends aligning perfectly, coolant and transmission lines route cleanly along the chassis rails, reducing the likelihood of kinks or abrasion. This plug-and-play approach ensures a professional underhood appearance and minimizes the risk of installation errors. Technicians and DIY enthusiasts alike benefit from a fast, reliable swap process that respects the vehicle's original engineering.
Coating Choices for Lasting Corrosion Resistance
Choose the naturally bright finish of bare aluminum or apply a black epoxy coating for an additional defense layer against oxidation and road debris. The black epoxy is precision sprayed to factory tolerances, preserving seal integrity at tank seams and inlet ports while standing up to salt spray and moisture exposure. Both options maintain full thermal efficiency, allowing the core to transfer heat unimpeded. The protective coating reduces maintenance intervals by keeping coolant passages clear and minimizing the risk of surface corrosion. This flexibility enables builders to match the radiator’s appearance to their vehicle’s style without sacrificing performance.
