CSF Heat Exchanger Upgrade for the 09-15 CTS-V

These heat exchangers feature CSF's high efficiency "B" tubes. 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.”

Each Radiator Is:
-Individually leak tested
-Vibration cycle tested
-Thermal cycle tested
-Wind tunnel cycle tested.
-Burst pressure and impulse cycle tested for strength
-Salt spray tested for corrosion
-10 foot box "drop test" to ensure packaging protection
-30 point fitment inspection on critical dimensions to ensure OE fitment with no modifications necessary

CSF takes pride in manufacturing the highest quality aftermarket and performance parts for your race car. As both automotive professionals and enthusiasts we know exactly what it takes to perform at peak levels on both the track and street. That is why the CSF heat exchanger is hands down the best direct replacement cooling system for your existing OEM heat exchanger.
