LS and LT Radiator for 1968-1972 A-Body and Monte Carlo

When you install an LS or LT engine into a 1968-72 A-Body or a 1970-72 Monte Carlo, the extra heat output demands a cooling solution that keeps pace. This 1968-1972 A-Body and 1970-1972 Monte Carlo Radiator (Manual Trans) meets that need with its direct bolt in design and an all aluminum core welded for strength and efficient heat transfer. Built for straightforward fitting into the factory mounting points, it delivers LS and LT compatibility without frame alterations or custom brackets.

Precision TIG Welded Aluminum Construction

This radiator features a fully TIG welded design that bonds premium aluminum tanks to a high efficiency core, creating a single structure that resists leaks and handles vibration without fatigue. TIG welding offers a cleaner, more controlled fusion than conventional methods, ensuring each joint achieves maximum strength while keeping heat transfer paths free of contaminants. The use of aluminum not only keeps the assembly lightweight but also provides excellent resistance to corrosion, so the radiator retains its integrity and performance over time. Made in the USA, this build quality delivers consistent fit and finish for classic GM installations.

Superior Thermal Management for LS and LT Engines

Modern LS and LT powerplants generate significant heat, and this radiator core is engineered to reject that heat quickly to maintain stable engine temperatures under load. The all-aluminum construction maximizes thermal conductivity, while the tank and tube layout promote rapid coolant flow and even distribution. By expelling heat more efficiently, the system reduces the risk of hot spots, helping preserve head gasket life and avoiding power loss due to excessive temperatures. This enhanced cooling capability ensures reliable performance whether cruising on the street or pushing hard at the track.

Direct Bolt In Fitment for Classic A Body and Monte Carlo

Designed specifically for 1968-1972 A-Body vehicles and 1970-1972 Monte Carlo models with manual transmission, this radiator bolts directly into the factory mounting points without the need for frame alterations or custom brackets. The precise alignment of inlet and outlet ports matches original hose routing, so installation is straightforward for both professional shops and enthusiast mechanics. By preserving the stock mounting geometry, you maintain correct hood clearance, radiator support integrity and ease of service access.

Finish Options Balancing Aesthetics and Protection

Choose a bare aluminum finish for a polished, vintage look that highlights the core's craftsmanship, or opt for a black epoxy coating that stands up to road debris, moisture and chemical exposure. Both finishes allow excellent heat dissipation, but the epoxy layer adds an extra barrier against pitting and environmental wear. This dual-choice approach lets builders match the radiator to their engine bay style while ensuring long-term durability under harsh driving conditions.
