Good morning ! The name of the game is heat transfer or heat rejection. The more surface area that the coolant can touch, with the more fins per inch that would still allow for proper air flow, the faster the heat is transferred to the air. The thicker the tube doesn’t essentially allow for more heat transfer. It allows for a stronger tube. But if the tube has less of a surface area internally than the Thermal Efficiency Rating would be less effective.
We carry and sell Cascadia radiators with frames, and for a 2016 Freightliner Cascadia, we will need an OE# to cross reference. Hopefully this helped answer your question, if you have any other questions or concerns about your radiator and/or fitment feel free to give Josh Hurley a call at 800-228-1103 ext 292.
Fact! Mine just went up at only 3 years.
I have increased the tube density of the Cascadia radiator's core.
Do you think this will be effective?
