Now, you will have a radiator that will cool anything and you still have the stock attachment of the stubs to the recipient vehicle so you can use simple hand tools to disassemble the whole mess later if you have to. It'll all come out as one piece -- because it is one piece. | Now, you will have a radiator that will cool anything and you still have the stock attachment of the stubs to the recipient vehicle so you can use simple hand tools to disassemble the whole mess later if you have to.

| − | + | Most cars from 1960 and up used cross flow radiators. One of the reasons was a lower stance of the overall automobile, two, the vehicles were getting wider and more cooling area was required to cool the larger engines. Cross flow rads had a tank with an inlet/outlet placed on either side. The water entered on one side and passed through the core of the rad, was cooled by the air flow and the heat escaped through convection to the outside air. Engineers found that the longer the liquid was exposed to the cooling flow of air through the rad core, more heat could be extracted from the flowing water. They slowed down the water travel by increasing the size of the water pump pulleys, but that had its limitations. They also added more rows of core, but that too had limitations. Road course racers in 1969, found a way to keep cooling to a simple easy form. To do this, they pulled the tanks off the rads that they were using and placed baffle plates in the tank covers. The baffles were placed so as to divide the rad core section into three distinct areas. Water would enter the upper rad inlet on the right side and would flow across the top section of the rad to the left side, a baffle plate located 2/3rds of the way down the tank caused the coolant to flow across the rad to the right side to the right rad tank. The coolant, couldn't rise upwards because a baffle plate located a 1/3rd of the way down stopped it and forced it to head down lower in the right tank, where it again was drawn across the rad core to the lower left tank outlet and out to the engine. This serpentine course that the coolant took, allowed the coolant to be cooled THREE TIMES by the cooling air flow coming through the core area. Excellent idea!, you say, why don't they do that to all cars today? In a closed course atmosphere, the theory works, but in real everyday life the average auto would never warm up to operating temperature during the daily commute. That's why ONLY HOT RODDERS are privileged to use this system. | |
