1973-1974 X-Body Nova and Ventura LS and LT Radiator
When your project involves an LS or LT engine swap into a 1973-1974 Chevy Nova or Pontiac Ventura, this X-Body radiator delivers the coolant flow and thermal control needed to keep temperatures in check. Crafted 100 percent in the USA with TIG welded aluminum tanks and core, it drops into the original mounting points and clears factory fan assemblies and hoses without cutting or bending. Finish options include bare aluminum for a period correct look or black epoxy coating for long term corrosion resistance and minimal prep before installation. Precision machined inlets and original style brackets align with manual transmission plumbing to simplify fitment whether you are working on a home build or in a professional shop.
Precision TIG welded aluminum construction
Every joint in this radiator is formed using TIG welding, a process that fuses aluminum with a stable arc and creates consistently strong bonds. By eliminating weak points and minimizing distortion, the method produces a tank and core assembly that resists stress from rapid temperature shifts when an LS or LT engine fires up. The leakproof welds maintain coolant pressure over years of daily driving or spirited track use. Fabricated entirely in the USA, this approach yields a single piece structure that holds its shape and keeps coolant inside where it belongs.
Efficient heat transfer with pure aluminum core
The all aluminum core harnesses the metal's natural ability to conduct heat, drawing warmth away from the engine block quickly and dispersing it across a wide surface area. Compared to heavier copper and brass units, this design shaves front end mass while keeping operating temperatures stable whether you're cruising or sitting idle in traffic. Aluminum also resists internal corrosion, so flow remains consistent without blockages or coolant leaks over time. The result is reliable cooling that matches the demands of modern LS and LT powerplants in an X-body frame.
Direct fitment for 1973 1974 X body chassis
This radiator drops into the stock mounting points on Nova and Ventura X body frames without any cutting or bending, preserving the integrity of the factory sheet metal. Original style inlet and outlet locations align precisely with manual transmission plumbing and factory hose routing, eliminating common clearance headaches. Precision machined brackets ensure a snug install that clears the fan shroud and accessory drive components. Whether you're tackling this in a home garage or a professional shop, the plug-and-play fitment saves time and reduces frustration.
Durable finish choices for lasting corrosion protection
Owners can choose a clean bare aluminum surface for a period correct appearance or select a black epoxy coating that seals every exterior surface against moisture and road chemicals. Both finishes ship ready to install, so no additional masking or painting is required before go time. The epoxy option offers an extra shield from pitting and oxidation, preserving both form and function through wet winters and humid summers. This finish flexibility ensures your cooling system looks as good as it performs for years to come.
