1973-1974 Chevy Nova and Pontiac Ventura LS and LT Swap Radiator
Swapping an LS or LT powerplant into a 1973-1974 Nova or Ventura often stalls when a proper cooling solution cannot fit within the stock frame points. The 1984-1989 Corvette Radiator (Auto and Manual Trans) addresses this by matching original X Body mounting locations and aligning with factory hose paths for both manual and automatic transmissions. This radiator is crafted in the USA from a full aluminum core and tanks fully TIG welded for dependable strength under varying loads and resists corrosion without heavy maintenance, ensuring stable operating temperatures whether you are cruising highways or idling in traffic. With both bare and black epoxy finishes available straight from the box you get moisture and chemical resistance or a period correct look while installation requires no cutting of sheet metal or brackets so factory fan shrouds and hose routings remain intact.
Precision TIG Welded Aluminum Structure
The radiator body and tanks are assembled using a precision TIG welding process that fuses high quality aluminum with meticulous arc control. This manufacturing method produces uniform weld beads that resist cracking or warping under repeated temperature cycles. With a leakproof design trained to maintain coolant pressure over thousands of miles, the single piece structure resists fatigue from engine vibration and road impacts. Built in the USA, each joint undergoes strict inspection to ensure it meets exacting strength requirements for daily driving or spirited use.
Optimized Thermal Response with Pure Aluminum Core
This radiator features a full aluminum core chosen for its superior conductivity and low mass. The thin wall tubes and brazed fins create a wide surface area that pulls heat from the LS or LT powerplant and disperses it rapidly into oncoming airflow. Compared to older copper units, this arrangement sheds heat more quickly and helps maintain consistent engine temperature in stop and go traffic or sustained highway cruising. The material also resists internal corrosion, keeping coolant passages clear and flow rates steady over years of operation.
Effortless Fitment to Original X Body Frame
Designed specifically for the 1973 and 1974 Chrysler X body platform, this radiator installs directly at the factory mounting points without any cutting or bending of sheet metal. Inlet and outlet locations are machined to match both manual and automatic transmission plumbing and original hose routing, preserving clearance for the stock fan shroud and accessory drives. By eliminating custom bracket fabrication and plumbing modifications, the plug in design reduces installation time and avoids common clearance issues in tight engine bays.
Bare Aluminum and Epoxy Options for Corrosion Protection
Buyers can select a clean bare finish that highlights the natural metal or a black epoxy coating engineered to guard against moisture and road chemicals. Both options arrive fully finished so there is no need for masking or additional paint prep before installation. The epoxy layer seals every exterior surface against pitting and oxidation in harsh environments, while the raw metal finish offers a period correct appearance with minimal maintenance. This choice allows custom engine swaps to maintain both function and style.
