Manual Transmission Radiator with Fan for LT Engine Application
For enthusiasts tackling an LT power swap into a 1973-1974 Nova with a manual transmission this radiator assembly provides the precise cooling capacity needed while honoring the factory clearance for linkage and pan. Featuring a multi row aluminum core and a shroud integrated electric fan it maintains steady coolant flow across a wider temperature range when airflow is limited by lower speeds or traffic conditions. Its direct fit mounting pattern secures to original frame rails and transmission brackets without trimming or welding sheetmetal. The sealed fan motor and reinforced mounting points deliver dependable engine coolant circulation under spirited acceleration or idle conditions.
Efficient Heat Dissipation with Multi Row Aluminum Core
At the heart of the 1973-1974 Nova radiator is a multi row aluminum core that maximizes surface area for efficient heat transfer. Each coolant tube feeds into parallel fin banks, removing thermal energy uniformly and preventing localized overheating during high load. The aluminum construction also delivers a balance of strength and light weight, minimizing added mass under the hood. With its fine tube layout and increased coolant volume, this core design maintains a stable temperature even when the engine operates near its performance limits in varied driving conditions. Consistent cooling capacity helps protect internal engine components and preserves performance over long sessions.
Integrated Shroud Fan for Reliable Cooling at Low Speeds
An integrated electric fan sits neatly within the molded shroud to make up for limited airflow at low vehicle speeds. When idling in traffic or crawling up steep grades, the fan pulls air through the core to maintain optimal coolant flow. The sealed motor design resists moisture and airborne particles, so it delivers reliable operation without frequent inspection. By aligning the fan blades precisely with the core openings, this combined fan and shroud assembly eliminates turbulence and maximizes air throughput. The direct current motor also offers quick response to rising coolant temperatures, engaging the fan at the exact threshold needed to protect the engine.
Precision Direct Fit Preserves Factory Layout
The radiator assembly bolts directly to the Nova's original frame rails and transmission brackets using factory mounting points, preserving the vehicle's stock layout. Installers will not need to perform trimming or welding on sheet metal, making the process straightforward even in a home garage setting. Special attention in the design phase ensures compatibility with the LT engine's driver side water pump offset and the manual transmission oil pan profile. Exact bracket spacing maintains proper clearance for throttle linkage, heater hoses and other accessories. As a result, the finished installation looks factory approved and functions without interference or rattles.
Durable Sealed Motor and Reinforced Mount Points
Heavy duty reinforcement at every fan shroud joint and mounting point guarantees long service life under both spirited acceleration and sustained idle conditions. Bracket gussets and sturdy fasteners distribute vibration loads evenly to prevent stress fatigue in the aluminum core. The fan motor's fully sealed housing keeps out contaminants like dust and engine vapors, extending maintenance intervals and reducing the risk of failure. Together, these design choices provide continuous coolant circulation, ensuring that the engine stays within safe operating temperatures during track days or daily driving. The result is a reliable cooling solution tailored for classic Nova enthusiasts.
This radiator assembly delivers reliable cooling and a direct fit for your LT engine swap.
