1973-1974 Chevy Nova and Pontiac Ventura Radiator for LS and LT Engine Swaps
When integrating an LS or LT engine into your 1973 to 1974 Chevy Nova or Pontiac Ventura, keeping coolant temperatures in check is vital for swap reliability. The 1973-1974 Nova Radiator (AutoTrans) uses 100 percent TIG welded aluminum tanks and core to withstand higher heat loads while minimizing added weight. Crafted for X Body chassis it aligns perfectly with factory mounting points and automatic transmission ports for hassle free hose routing and clearance around belt driven components.
Precision TIG Welded Aluminum Structure
The radiator's tanks and core are joined using a TIG welding process that delivers exceptionally clean, precise bonds. This method creates a leak free seal and adds mechanical strength at each joint while preserving aluminum's natural resistance to corrosion. By eliminating weak spots that can develop under repeated heat cycles, the structure remains robust even under aggressive driving or demanding engine swap conditions. The result is a lightweight yet highly durable assembly that supports reliable coolant flow without excess mass.
Efficient Thermal Control for LS and LT Engines
Manufactured from premium aluminum, the core excels at drawing heat away from the coolant and expelling it into passing air. Aluminum's superior conductivity and the optimized fin density allow rapid heat rejection to keep modern LS and LT powerplants operating within their ideal temperature range. This design prevents engine knock and power loss during extended highway runs or spirited track sessions. Balanced core thickness ensures maximum cooling capacity without compromising airflow or adding undue front-end weight.
Direct Fit Installation on X Body Chassis
Specifically engineered for 1973 to 1974 Chevy Nova and Pontiac Ventura frames, the radiator aligns flawlessly with factory mounting points on the X Body platform. Inlet and outlet ports match the hose locations of automatic transmission models, eliminating the need for adapters or custom plumbing. Clearance around belt-driven accessories is maintained, so no modifications to brackets or frame rails are required. This precision fitment streamlines installation, letting installers focus on system integration rather than fabrication.
Protective Black Epoxy or Bright Bare Aluminum Finishes
Buyers may choose the natural shine of bare aluminum or the added defense of a black epoxy coat to suit their build's aesthetic. The epoxy layer acts as a barrier against moisture, road debris, and corrosion while maintaining adhesion under thermal cycling. Bare aluminum highlights the crisp welds and fin work, offering a classic metallic look that stands out in any engine bay. Both finish options undergo stringent quality checks to ensure uniform coverage and long-term resilience in real-world conditions.
