CSF radiators are offered in the industry's widest variety, servicing thousands of vehicle-specific and universal applications … including every brand from Acura to Volkswagen. Whether your radiator is copper-brass, plastic-copper-brass, plastic-aluminum, or all-aluminum, CSF has you covered with the same materials and style as OE. CSF manufactures the highest quality aftermarket replacement radiators, with the strongest and most efficient components available in the industry.

All CSF radiators undergo a rigorous testing process in their state-of-the-art testing lab. CSF's procedures and requirements set the bar for cooling system reliability and performance:

* Individually leak tested
* Vibration-cycle tested
* Thermal-cycle tested
* Wind tunnel tested for optimal radiator core cooling efficiency
* Burst pressure and impulse-cycle tested for strength
* Salt spray tested for corrosion protection
* 10 ft. box drop test to ensure packaging protection
* 30-point fitment inspection on critical dimensions to ensure drop-in fit with no modifications (where applicable)
