LS and LT Radiator for 1973-1974 Chevy Nova and Pontiac Ventura
The 1984-1989 Corvette Radiator (Auto and Manual Trans) is built to provide precise coolant circulation and thermal control when dropping an LS or LT engine into a 1973-1974 Chevy Nova or Pontiac Ventura. Its all aluminum core and tanks are fully TIG welded in the USA for reliable strength and consistent flow under demanding conditions. Mounts align with stock frame points and clear factory fan shrouds and hose routings without any cutting or bending. Available in bare finish or black epoxy coating it offers corrosion resistance and minimal prep on installation.
Structural Integrity from Precision TIG Welds
Every joint on this radiator is crafted using TIG welding, a process that fuses high quality aluminum with a stable arc to create exceptionally strong bonds. By delivering uniform heat and precise control, TIG welds minimize distortion and eliminate weak spots that can develop under rapid temperature changes. This method results in a leakproof assembly that maintains coolant pressure through years of daily driving or spirited performance runs. Manufactured entirely in the USA, the single piece structure holds its shape under stress and ensures coolant stays contained where it belongs, providing reliable operation mile after mile.
Rapid Heat Rejection with Pure Aluminum Core
The all aluminum core exploits the metal’s natural conductivity to draw heat away from the engine block and disperse it evenly across a broad surface area. Compared to heavier copper and brass units, this design reduces front end mass without compromising cooling capacity, making it ideal for compact X body layouts. Aluminum also resists internal corrosion, so flow remains consistent and free of blockages over time. The result is stable operating temperatures during highway cruising, traffic jams or track sessions, matching the demands of modern LS and LT powerplants in a classic chassis.
Plug and Play Fitment for X Body Frame
Designed specifically for 1973-1974 Nova and Ventura X body frames, this radiator drops into the original mounting points without any cutting or bending. Precision machined inlet and outlet locations align with manual transmission plumbing and factory hose paths, eliminating clearance headaches and trimming hours from the installation process. The original style brackets clear factory fan shrouds and accessory drives, so whether you are working in a home garage or a professional shop, you benefit from a seamless upgrade that preserves factory sheet metal and streamlines plumbing.
Corrosion Defense with Dual Finish Options
Choose between a clean, bare aluminum surface for a period correct appearance or a black epoxy coating that seals every exterior surface against moisture and road chemicals. Both finishes arrive ready to install, so no additional masking, sanding or painting is required. The epoxy option delivers extra protection from pitting and oxidation during wet winters or humid summers, while the bare version showcases the raw metal for an authentic look. This finishing flexibility ensures your cooling system not only performs at its best but also retains its appearance through years of use.
