Manual Transmission Radiator for LS and LT Engines in 1968-1972 A-Body and 1970-1972 Monte Carlo
When your project involves dropping an LS or LT powerplant into a classic A-Body or Monte Carlo with manual transmission the 1968-1972 A-Body and 1970-1972 Monte Carlo Radiator (Manual Trans) ensures reliable temperature control through precise coolant flow. Inlet and outlet ports follow factory hose routing and original bolting locations to remove any need for custom brackets. Its TIG welded aluminum core and matching tanks drive heat rejection while resisting corrosion over time. Service access remains straightforward under the hood for routine inspections and coolant changes.
Precision TIG Welding for Leak Resistance
Each radiator is assembled using a Tig welding process that forms a uniform bond between the high grade aluminum core and tanks with a non consumable tungsten electrode. This method creates consistent bead profiles free of filler irregularities, reducing stress points that can lead to coolant seepage under continuous vibrations and heat cycles common in performance applications. All weld seams are subjected to visual and pressure inspections to verify integrity before shipment, allowing technicians to confirm proper fusion at each joint. By maintaining strict quality standards, the radiator sustains a sealed coolant path even under heavy engine load and high rpm operation. Built in the USA, this precision technique maximizes fatigue strength and ensures the assembly remains free from micro leaks for extended service intervals.
Efficient Heat Dissipation with High Quality Aluminum Core
The radiator employs a pure aluminum core designed to take full advantage of the metal's natural thermal conductivity, rapidly moving heat away from the coolant. Internal tubes are spaced to promote even fluid distribution while numerous thin fins increase surface area to capture airflow and prevent hot spots in the coolant stream. This all aluminum assembly cuts front end weight compared to traditional copper units, improving vehicle responsiveness and balance. Under sustained driving conditions with LS or LT powerplants, it keeps temperatures within a stable range for consistent horsepower output and protects critical engine components. The core design also resists corrosion by eliminating dissimilar metal contact points, ensuring long term performance in harsh climates and high humidity environments.
Corrosion Protection via Coating Options
Choose between a natural bare aluminum surface that highlights the machining detail or an epoxy finish for enhanced resistance against road chemicals and moisture. The black epoxy process covers all contact surfaces evenly, creating a protective barrier that guards against pitting and prolongs service life in salted or coastal regions. Both finish options undergo adhesive pull testing and salt spray trials to ensure uniform coverage and adhesion without impairing heat exchange. The untreated aluminum exhibits maximum passive cooling capacity, while the coated version delivers a durable shield against airborne debris and brake dust. Either choice maintains core efficiency and supports the aesthetics of both stock restorations and custom builds.
Straightforward Bolt On Installation for Classic Chevy Bodies
Specifically engineered for 1968 to 1972 A Body sedans and 1970 to 1972 Monte Carlo models with manual transmission, this radiator uses factory bolt positions and original hose routing to eliminate the need for custom brackets. It preserves hood clearance and aligns with chassis geometry specified by the original automaker, ensuring components such as the fan shroud and coolant overflow tank fit as intended. Inlet and outlet ports mirror OEM locations for seamless integration with aftermarket water pumps and heater cores. This direct bolt on design reduces build time by removing fabrication steps and limits potential leak points in the cooling system. Routine service access remains effortless thanks to maintained clearance around bleed valves and drain fittings, making coolant changes and inspections faster for restorers and performance builders alike.
