New Flex-A-Lite performance radiators use a unique Extruded Tube Core technology, replacing multi-core radiators with an advanced design.
The Extruded Tube Core increases contact area between coolant and the aluminum tubes for better heat rejection and cooling.
The cooling fins have been designed with louver patterns cut into them to direct airflow, improving heat rejection and cooling.
The Flex-A-Lite Extruded Tube Core Radiators are significantly stronger and have a 100-psi burst rating.
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.
