Flexalite Extruded Core Radiator and Dual Electric Fans 1973-1987 Full Size 1/2
Flex-A-Lite® Extruded Core Technology is the future of performance aluminum radiators, replacing multi-core radiators with a new advanced design. Flex-A-Lite® Extruded Core Radiators provide significantly better cooling with a stronger, more durable and lighter design.
This direct-fit radiator is engineered to bolt into a 1973-1987 full-size 1/2-ton Chevrolet or GMC truck or SUV. No cutting or drilling is required for installation, and the radiator will mount using the factory location and equipment. Includes a fully-shrouded dual-fan system that moves 4,600 cfm of airflow and a Variable Speed Controller. Radiator includes 22-24 lbs. cap and train petcock.
Key features and benefits of the Flex-A-Lite® Extruded Tube Core Radiators include:
• Increased contact area between the coolant and aluminum tubes for better heat rejection and cooling.
• A flat surface on which to braze the cooling fins, maximizing the contact between the tubes and fins for increased heat rejection and better cooling.
• The cooling fins have been designed with louver patterns cut into them to direct airflow, improving heat rejection and cooling.
• Wind-tunnel testing has shown that this Extruded Tube Core technology is significantly more efficient for cooling than standard tube radiators.
• The Flex-A-Lite® Extruded Tube Core Radiators are significantly stronger and have a 100-psi burst rating.
• The Flex-A-Lite® Extruded Tube Core Radiators include a corner subhead, reinforcing the cooling tube to header connection, an area prone to cracking and leaking in other brands of aluminum radiators.
