Project 5.0 Mustang: Improving the Breathing With Ford Racing and Cooling with CSF


Now our engine is ready to get serious with disassembly.
The radiator fan is removed.
The stock radiator comes out.
The difference between stock and the CSF radiator is super obvious.  The CSF’s much stronger all TIG welded construction can withstand higher pressure which raises the boiling point and improves cooling.   If you can see the welded line abut 2/3’s of the way down the end tanks, those are the baffles that make the CSF radiator a dual path by forcing the coolant to reverse flow through the core.  This makes the radiator about 15% more efficient.
The CSF core uses their signature full thickness B-Tube construction which has a lot more heat conducting surface area than a standard tube and is much stronger with internal reinforcement. The B-Tube is 15% more efficient at heat exchange than a traditional tube.
You can see that the CSF radiators core is around three times thicker than stock.  Notice the crimped on end tanks of the stock radiator?  These can easily spring a leak at higher pressure. CSF’s TIG welded end tanks won’t do that ever.
