73-76 Corvette Radiator

The 73-76 Corvette Radiator by Cold Case Radiators is the modern cooling solution serious C3 Corvette owners turn to when stock brass-and-copper units fail or prove inadequate for street and weekend track duty. This all-aluminum replacement is designed for carbureted or early fuel-injected small-block or big-block Corvettes from this generation, providing reliable cooling during summer cruises and spirited driving sessions.

Engineered to handle both idle-to-cruising stability and sustained performance, this radiator features high-efficiency aluminum core construction and optimized fin density to maximize heat dissipation. The larger cooling surface area compared to original equipment absorbs more BTU capacity per minute, which is critical when upgrading ignition systems, carburetors, or cam profiles that generate additional underhood heat.

With dual upper and lower tank construction, this radiator ensures even coolant distribution across core tubes, reducing hot spots and preventing localized boiling. At 23.6 pounds, the unit's aluminum construction reduces overall vehicle weight while improving handling balance, making it an excellent choice for those looking to enhance their Corvette's performance.
