LS and LT Radiator for 1973-1974 Chevy Nova and Pontiac Ventura
When adapting an LS or LT engine to a 1973 to 1974 Chevy Nova or Pontiac Ventura, a radiator that aligns with the original X Body mounts and ports can be a major hurdle. The 1984 to 1989 Corvette Radiator for automatic and manual transmissions removes installation guesswork by matching factory fill neck and bracket placements to the inch. Its fully TIG welded aluminum core and tanks resist corrosion while guiding coolant through an optimized fin layout for reliable thermal management under sustained demand. Designed specifically for the X Body frame this radiator preserves clearance around belt drives and transmission lines to simplify assembly and maintain a factory appearance.
Precision TIG Welded Aluminum for Enduring Strength
This radiator employs TIG welding on every joint between tanks and core channels to create a seamless bond that withstands pressure fluctuations. TIG welding allows precise control over weld bead and ensures full penetration without introducing filler material contamination. In high temperature conditions the seamless joints resist leaks and maintain cooling system integrity under sustained demand. Each weld is inspected by hand in the USA to guarantee consistent build quality and a long service life that delivers reliability on the road.
Optimized Aluminum Core Design for Efficient Heat Transfer
The core is crafted from high quality aluminum chosen for its rapid thermal conductivity. Carefully arranged fin density and channel profile maximize the surface area in contact with air while minimizing airflow resistance. This configuration enables quick heat rejection from coolant when the engine is driven hard or on extended highway runs. The lightweight construction also reduces front mass and helps preserve natural steering feel and chassis dynamics.
Direct Bolt In Fit for X Body Nova and Ventura
Engineered specifically for the 1973 to 1974 Chevy Nova and Pontiac Ventura, this radiator mounts directly to the original brackets with no adapter plates needed. The fill neck placement matches the factory location to the inch, and clearance is maintained around belt drive pulleys and transmission lines. This direct bolt in installation removes guesswork, avoids frame modifications, and helps builders preserve an authentic engine bay appearance. Simple alignment with chassis supports also cuts installation time and simplifies hose routing.
Choice of Natural or Coated Finish for Lasting Corrosion Defense
Consumers can choose a natural bare aluminum look or a durable black epoxy coat that adds surface protection. The bare surface forms a self limiting oxide layer to slow corrosion while showcasing clean weld details. The epoxy finish resists chips, debris, and moisture exposure without cracking under repeated heat cycles. Both options are inspected for full coverage and verified to fit original mount points and hose connections with precision.
