CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology.


Unlike a regular oval shape “O” type radiator tube, CSF uses a specially engineered tube in a shape of a “B.” These “B-tubes” are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal “O” shape tubes that are welded.

The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes – producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With “B-tubes” you are able to get “dual liquid laminar flow.”

High Efficiency multi-louvered fins

CSF uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.


CSF aims to lead the cooling system industry by introducing new technologies and manufacturing processes that allows us to be on the cutting edge of heat transfer innovation.

ENDTANK designs

OEM crimped-on end tanks are known to leak or deteriorate over extended periods of time and in high-boost applications. CSF’s 100% TIG-welded aluminum end tanks are stronger for longevity and durability on high-performance vehicles. They withstand increased boost pressures from bolt-on modifications, higher performance tunes, and upgraded turbochargers. Many of CSF’s complete assemblies come included with many additional features such as additional ports for methanol injection or boost pressure reference.


oil coolers

CSF’s expanding range of oil cooler applications and technology is leading the industry for high-performance as well as construction, industrial, and agricultural. CSF’s oil coolers are suitable and designed for engine oil, transmission oil, power steering, differential fluid, or can be used as a substitute for water heat exchange in a higher boost or more vibration intensive application.
